From bda663d36b94c723153246a4231bbc0f1cd1836e Mon Sep 17 00:00:00 2001 From: Robert Moore Date: Fri, 16 Sep 2005 16:51:15 -0400 Subject: [ACPI] ACPICA 20050916 Fixed a problem within the Resource Manager where support for the Generic Register descriptor was not fully implemented. This descriptor is now fully recognized, parsed, disassembled, and displayed. Restructured the Resource Manager code to utilize table-driven dispatch and lookup, eliminating many of the large switch() statements. This reduces overall subsystem code size and code complexity. Affects the resource parsing and construction, disassembly, and debug dump output. Cleaned up and restructured the debug dump output for all resource descriptors. Improved readability of the output and reduced code size. Fixed a problem where changes to internal data structures caused the optional ACPI_MUTEX_DEBUG code to fail compilation if specified.

The code has been optimized to simplify and eliminate duplicated code, CPU stack use has been decreased by optimizing function parameters and local variables, and naming conventions across the manager have been standardized for clarity and ease of maintenance (this includes function, parameter, variable, and struct/typedef names.) All Resource Manager dispatch and information tables have been moved to a single location for clarity and ease of maintenance. One new file was created, named "rsinfo.c". The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to guarantee that the argument is not evaluated twice, making them less prone to macro side-effects. However, since there exists the possibility of additional stack use if a particular compiler cannot optimize them (such as in the debug generation case), the original macros are optionally available. Note that some invocations of the return_VALUE macro may now cause size mismatch warnings; the return_UINT8 and return_UINT32 macros are provided to eliminate these. (From Randy Dunlap) Implemented a new mechanism to enable debug tracing for individual control methods. A new external interface, acpi_debug_trace(), is provided to enable this mechanism. The intent is to allow the host OS to easily enable and disable tracing for problematic control methods. This interface can be easily exposed to a user or debugger interface if desired. See the file psxface.c for details. acpi_ut_callocate() will now return a valid pointer if a length of zero is specified - a length of one is used and a warning is issued. This matches the behavior of acpi_ut_allocate().

This essentially entails recognizing that these processors support non-aligned memory transfers. Previously, all 64-bit processors were assumed to lack hardware support for non-aligned transfers. Completed conversion of the Resource Manager to nearly full table-driven operation. Specifically, the resource conversion code (convert AML to internal format and the reverse) and the debug code to dump internal resource descriptors are fully table-driven, reducing code and data size and improving maintainability. The OSL interfaces for Acquire and Release Lock now use a 64-bit flag word on 64-bit processors instead of a fixed 32-bit word. (Alexey Starikovskiy) Implemented support within the resource conversion code for the Type-Specific byte within the various ACPI 3.0 *WordSpace macros. Fixed some issues within the resource conversion code for the type-specific flags for both Memory and I/O address resource descriptors. For Memory, implemented support for the MTP and TTP flags. For I/O, split the TRS and TTP flags into two separate fields.

The GPE initialization has been split into two parts in order to defer execution of the _PRW methods (Power Resources for Wake) until after the hardware is fully initialized and the SCI handler is installed. This allows the _PRW methods to access fields protected by the Global Lock. This will fix systems where a NO_GLOBAL_LOCK exception has been seen during initialization. Fixed a regression with the ConcatenateResTemplate() ASL operator introduced in the 20051021 release. Implemented support for "local" internal ACPI object types within the debugger "Object" command and the acpi_walk_namespace() external interfaces. These local types include RegionFields, BankFields, IndexFields, Alias, and reference objects. Moved common AML resource handling code into a new file, "utresrc.c". This code is shared by both the Resource Manager and the AML Debugger.

This should eliminate AE_AML_METHOD_LIMIT exceptions seen on some machines. This also fixed a related regression with the mechanism that detects and corrects methods that cannot properly handle reentrancy (related to the deployment of the new OwnerId mechanism.) Eliminated the pre-parsing of control methods (to detect errors) during table load. Related to the problem above, this was causing unwind issues if any errors occurred during the parse, and it seemed to be overkill. A table load should not be aborted if there are problems with any single control method, thus rendering this feature rather pointless. Fixed a problem with the new table-driven resource manager where an internal buffer overflow could occur for small resource templates. Implemented a new external interface, acpi_get_vendor_resource() This interface will find and return a vendor-defined resource descriptor within a _CRS or _PRS method via an ACPI 3.0 UUID match. (from Bjorn Helgaas) Removed the length limit (200) on string objects as per the upcoming ACPI 3.0A specification. This affects the following areas of the interpreter: 1) any implicit conversion of a Buffer to a String, 2) a String object result of the ASL Concatentate operator, 3) the String object result of the ASL ToString operator.

Objects are now created only during the execute phase, at the moment the namespace creation operator is encountered in the AML (Name, OperationRegion, CreateByteField, etc.) This should eliminate ALREADY_EXISTS exceptions seen on some machines where reentrant control methods are protected by an AML mutex. The mutex will now correctly block multiple threads from attempting to create the same object more than once. Increased the number of available Owner Ids for namespace object tracking from 32 to 255. This should eliminate the OWNER_ID_LIMIT exceptions seen on some machines with a large number of ACPI tables (either static or dynamic). Enhanced the namespace dump routine to output the owner ID for each namespace object.

A null object is inserted in the package when a named reference cannot be located in the current namespace. Enabled via the interpreter slack flag which Linux has enabled by default (acpi=strict to disable slack). This should eliminate AE_NOT_FOUND exceptions seen on machines that contain such code. Implemented an optimization to the initialization sequence that can improve boot time. During ACPI device initialization, the _STA method is now run if and only if the _INI method exists. The _STA method is used to determine if the device is present; An _INI can only be run if _STA returns present, but it is a waste of time to run the _STA method if the _INI does not exist. (Prototype and assistance from Dong Wei) Implemented use of the C99 uintptr_t for the pointer casting macros if it is available in the current compiler. Otherwise, the default (void *) cast is used as before. Fixed some possible memory leaks found within the execution path of the Break, Continue, If, and CreateField operators. (Valery Podrezov) Fixed a problem introduced in the 20051202 release where an exception is generated during method execution if a control method attempts to declare another method.

At SuSE's suggestion, enabled all error messages without enabling function tracing, ie with CONFIG_ACPI_DEBUG=n Replaced all instances of the ACPI_DEBUG_PRINT macro invoked at the ACPI_DB_ERROR and ACPI_DB_WARN debug levels with the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros, respectively. This preserves all error and warning messages in the non-debug version of the ACPICA code (this has been referred to as the "debug lite" option.) Over 200 cases were converted to create a total of over 380 error/warning messages across the ACPICA code. This increases the code and data size of the default non-debug version by about 13K. Added ACPI_NO_ERROR_MESSAGES flag to enable deleting all messages. The size of the debug version remains about the same.

At the end of the serial console print we force enable the tx int in case we clobbered the tx interrupt status racing between the console and tty output. That way the extra tx interrupt causes the transmit path to restart not hang. It also makes the serial console printk use the FIFO. This is neccessary because some remote management devices fake serial console with FIFO and are confused into sending one packet per character over ethernet when we stall rather than filling the FIFO. In order to preserve existing reliability semantics the function waits for the serial queue to completely empty before returning. Both of these problems were identified by a Red Hat partner.

Looking closely at the code, I found some possible issues in the way we setup the MDIO lines during suspend along with slight divergences from what Darwin does when resetting it that may explain the problem. That patch change these and the problem appear to be gone for me at least... I also fixed an mdelay -> msleep while I was at it to the pmac feature code that is called when toggling the PHY reset line since sungem doesn't call it in an atomic context anymore.

The driver can typically detect port-loss during an interrupt context (i.e. via interrogation of a status IOCB's completion status [CS_PORT_LOGGED_OUT]. Due to the calling requirements of the fc_rport APIs, the driver would defer removal of the device to the default workqueue. If the work-item was preceded by an event which caused the port to obtain visibility (relogin successful, target re-logged into the topology), deferred removal could inadvertently drop the rport. The code also no longer defers removal via the default workqueue, instead opting for use of the driver's own DPC thread.

The SG_IO interface allows userspace to specify the CDB length. This is now ignored in scsi_execute_async and it is guessed using the COMMAND_SIZE macro, which is not always correct, particularly for vendor specific commands. This patch adds a cmd_len parameter to the scsi_execute_async interface to allow the caller to specify the length of the CDB.

The template has members that is set with appropriate values during driver initialisation. This change is done to support new controllers with minimal change to existing code. In future, for a new controller support, a template will be declared and its members initialised appropriately.

Tsirkin" Date: Mon, 30 Jan 2006 16:22:29 -0800 Subject: IB/mthca: Don't cancel commands on a signal We have run into the following problem: if a task receives a signal while in the process of e.g. destroying a resource (which could be because the relevant file was closed) mthca could bail out from trying to take a command interface semaphore without performing the appropriate command to tell hardware that the resource is being destroyed. As a result we see messages like ib_mthca 0000:04:00.0: HW2SW_CQ failed (-4) In this case, hardware could access the resource after the memory has been freed, possibly causing memory corruption. A simple solution is to replace down_interruptible() by down() in command interface activation. Signed-off-by: Michael S. Tsirkin [ It's also not safe to bail out on multicast table operations, since they may be invoked on the cleanup path too. So use down() for mcg_table.sem too. ] Signed-off-by: Roland Dreier --- drivers/infiniband/hw/mthca/mthca_cmd.c | 9 +++------ drivers/infiniband/hw/mthca/mthca_mcg.c | 14 ++++---------- 2 files changed, 7 insertions(+), 16 deletions(-) (limited to 'drivers') diff --git a/drivers/infiniband/hw/mthca/mthca_cmd.c b/drivers/infiniband/hw/mthca/mthca_cmd.c index be1791be627..69128fe60c5 100644 --- a/drivers/infiniband/hw/mthca/mthca_cmd.c +++ b/drivers/infiniband/hw/mthca/mthca_cmd.c @@ -199,8 +199,7 @@ static int mthca_cmd_post(struct mthca_dev *dev, { int err = 0; - if (down_interruptible(&dev->cmd.hcr_sem)) - return -EINTR; + down(&dev->cmd.hcr_sem); if (event) { unsigned long end = jiffies + GO_BIT_TIMEOUT; @@ -255,8 +254,7 @@ static int mthca_cmd_poll(struct mthca_dev *dev, int err = 0; unsigned long end; - if (down_interruptible(&dev->cmd.poll_sem)) - return -EINTR; + down(&dev->cmd.poll_sem); err = mthca_cmd_post(dev, in_param, out_param ? *out_param : 0, @@ -333,8 +331,7 @@ static int mthca_cmd_wait(struct mthca_dev *dev, int err = 0; struct mthca_cmd_context *context; - if (down_interruptible(&dev->cmd.event_sem)) - return -EINTR; + down(&dev->cmd.event_sem); spin_lock(&dev->cmd.context_lock); BUG_ON(dev->cmd.free_head < 0); diff --git a/drivers/infiniband/hw/mthca/mthca_mcg.c b/drivers/infiniband/hw/mthca/mthca_mcg.c index 77bc6c746f4..55ff5e5bcfe 100644 --- a/drivers/infiniband/hw/mthca/mthca_mcg.c +++ b/drivers/infiniband/hw/mthca/mthca_mcg.c @@ -154,10 +154,7 @@ int mthca_multicast_attach(struct ib_qp *ibqp, union ib_gid *gid, u16 lid) return PTR_ERR(mailbox); mgm = mailbox->buf; - if (down_interruptible(&dev->mcg_table.sem)) { - err = -EINTR; - goto err_sem; - } + down(&dev->mcg_table.sem); err = find_mgm(dev, gid->raw, mailbox, &hash, &prev, &index); if (err) @@ -242,7 +239,7 @@ int mthca_multicast_attach(struct ib_qp *ibqp, union ib_gid *gid, u16 lid) mthca_free(&dev->mcg_table.alloc, index); } up(&dev->mcg_table.sem); - err_sem: + mthca_free_mailbox(dev, mailbox); return err; } @@ -263,10 +260,7 @@ int mthca_multicast_detach(struct ib_qp *ibqp, union ib_gid *gid, u16 lid) return PTR_ERR(mailbox); mgm = mailbox->buf; - if (down_interruptible(&dev->mcg_table.sem)) { - err = -EINTR; - goto err_sem; - } + down(&dev->mcg_table.sem); err = find_mgm(dev, gid->raw, mailbox, &hash, &prev, &index); if (err) @@ -372,7 +366,7 @@ int mthca_multicast_detach(struct ib_qp *ibqp, union ib_gid *gid, u16 lid) out: up(&dev->mcg_table.sem); - err_sem: + mthca_free_mailbox(dev, mailbox); return err; } -- cgit v1.2.3 From fd9cfdd11be3b37b5c919b64b43990f14a1587bd Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Mon, 30 Jan 2006 16:45:11 -0800 Subject: IB/mthca: Semaphore to mutex conversions Convert semaphores to mutexes in mthca.

This support is in addition to the previously implemented unresolved reference support within the AML parser. If the interpreter slack mode is enabled (true on Linux unless acpi=strict), these unresolved references will be passed through to the caller as a NULL package entry. http://bugzilla.kernel.org/show_bug.cgi?id=5741 Implemented and deployed new macros and functions for error and warning messages across the subsystem. These macros are simpler and generate less code than their predecessors. The new macros ACPI_ERROR, ACPI_EXCEPTION, ACPI_WARNING, and ACPI_INFO replace the ACPI_REPORT_* macros. Implemented the acpi_cpu_flags type to simplify host OS integration of the Acquire/Release Lock OSL interfaces. Suggested by Steven Rostedt and Andrew Morton. Fixed a problem where Alias ASL operators are sometimes not correctly resolved. causing AE_AML_INTERNAL http://bugzilla.kernel.org/show_bug.cgi?id=5189 http://bugzilla.kernel.org/show_bug.cgi?id=5674 Fixed several problems with the implementation of the ConcatenateResTemplate ASL operator. As per the ACPI specification, zero length buffers are now treated as a single EndTag. One-length buffers always cause a fatal exception. Non-zero length buffers that do not end with a full 2-byte EndTag cause a fatal exception. Fixed a possible structure overwrite in the AcpiGetObjectInfo external interface.

It does this by intercepting the INQUIRY commands. In recent 2.6.15 testing, I discovered this to be failing. The cause was the driver assuming that the INQUIRY response data was in a simple single buffer, when it was actually a 1 element scatter gather list.

One notable change: the "early handoff" version always enabled an SMI IRQ ... and did so even if the pre-Linux code said it was not using EHCI (and not expecting EHCI SMIs). Looks like a goof in a workaround for some unknown BIOS version. This merged version only forcibly enables those IRQs when pre-Linux code says it's using EHCI. And now it always forces them off "just in case".

Then, if URB fails to complete, ub hangs until the device is unplugged. This does not happen often, becase we only allow one SCSI command per block device, but does happen (on multi-LUN devices, for example). The fix is to stop timer only when we actually going to change the state. The nicest code would be to have the timer stopped in URB callback, but this is impossible, because it can be called from inside a timer, through the urb_unlink. Then we get BUG in timer.c:cascade(). So, we do it a little dirtier.

This signals a socket shutdown, letting the socket user know that the game is up. I wrote this patch because of reports that pppd would keep connections open forever when the modem is disconnected. This patch does not fix that problem, but it's a step in the right direction. It doesn't help because the pppoatm module doesn't yet monitor state changes on the ATM socket, so simply never realises that the ATM connection has gone down (meaning it doesn't tell the ppp layer). But at least there is a socket state change now. Unfortunately this patch may create problems for those rare users like me who use routed IP or some other non-ppp connection method that goes via the ATM ARP daemon: the daemon is buggy, and with this patch will crash when the modem is disconnected. Users with a buggy atmarpd can simply restart it after disconnecting the modem.

Since there is some danger that users may not notice this change, the parameters are renamed to rcv_buf_bytes etc. The transmit buffer needs to be a multiple of the ATM cell size in length, while the receive buffer should be a multiple of the endpoint maxpacket size (this wasn't enforced before, which causes trouble with isochronous transfers), so enforce these restrictions. Now that the usbatm probe method inspects the endpoint maxpacket size, minidriver bind routines need to set the correct alternate setting for the interface in their bind routine.

While use of isoc transfer should still be considered experimental, it now works well enough to let users turn it on. Minidrivers signal to the core that they want to use isoc transfer by setting the new UDSL_USE_ISOC flag. The speedtch minidriver gets a new module parameter enable_isoc (defaults to false), plus some logic that checks for the existence of an isoc receive endpoint (not all speedtouch modems have one).

A new module parameter is added to select iso mode. It is set to iso by default because bulk mode doesn't work well at high speed rate (>3 Mbps for upload). We use UDSL_IGNORE_EILSEQ flags because ADI firmware doesn't reply to ISO IN when it has nothing to send [1]. [1] from cypress datasheet : The ISOSEND0 Bit (bit 7 in the USBPAIR Register) is used when the EZ-USB FX chip receives an isochronous IN token while the IN FIFO is empty. If ISOSEND0=0 (the default value), the USB core does not respond to the IN token. If ISOSEND0=1, the USB core sends a zero-length data packet in response to the IN token.

The current code attempts to add iospace for an entire root bus, which is inappropriate, and silently fails. When a pci device tries to use the iospace, a page fault is taken, as the iospace had not been mapped, and of course the page fault cannot be resolved. This only occurs for PCI adapters using pio, which may be why it hadn't been seen earlier (this seems to have been broken for a while). This patch has survived testing of dozens of slot add and removes.

It also triggers a message "Driver 'ide-scsi' needs updating - please use bus_type methods" from the driver core. The IDE core in 2.6.16-rc1 changed the location of an IDE driver's ->probe()/->remove()/->shutdown() methods: they are now in the ide_driver_t struct not in the gen_driver sub-struct. drivers/ide/ was updated for this change but ide-scsi.c wasn't. Hence the breakage. This patch repairs ide-scsi and also eliminates the driver core warning.

That makes the BE machines keep the bitmap internally in LE order - it does mean you can't use any other type of operations on the bitmap words but that looks to be OK in this instance. The efficiency tradeoff is very minimal as you would expect for something that ext2 uses. This allows us to remove bits_to_core(), bits_to_disk() and log->disk_bits. Also increment the mirror log disk version transparently to avoid sharing with older kernels that suffered from the 64-bit BE bug.

This is done in uart_set_options() for console, and in uart_add_one_port() for other ports. But there is a case the port->lock is not initialized by serial_core. If the setup function for the console was failed, it will not call uart_set_options() but the port is marked as console (uart_console(port) returns 1). It can happen if console was PCI port which can not detected at the time of register_console. This patch is to initialize port->lock for such console port. With this change, most of spin_lock_init() (some of them are labeled "Temporary fix.") in low-level serial drivers can be omitted.

When added for raid5/6, reshape again won't change the size of the array, at least not straight away.

Items (attributes) are similar to /proc/cpuinfo. 1) /sys/devices/system/cpu/cpuX/topology/physical_package_id: represent the physical package id of cpu X; 2) /sys/devices/system/cpu/cpuX/topology/core_id: represent the cpu core id to cpu X; 3) /sys/devices/system/cpu/cpuX/topology/thread_siblings: represent the thread siblings to cpu X in the same core; 4) /sys/devices/system/cpu/cpuX/topology/core_siblings: represent the thread siblings to cpu X in the same physical package; To implement it in an architecture-neutral way, a new source file, driver/base/topology.c, is to export the 5 attributes. If one architecture wants to support this feature, it just needs to implement 4 defines, typically in file include/asm-XXX/topology.h. The 4 defines are: #define topology_physical_package_id(cpu) #define topology_core_id(cpu) #define topology_thread_siblings(cpu) #define topology_core_siblings(cpu) The type of **_id is int. The type of siblings is cpumask_t. To be consistent on all architectures, the 4 attributes should have deafult values if their values are unavailable. Below is the rule. 1) physical_package_id: If cpu has no physical package id, -1 is the default value. 2) core_id: If cpu doesn't support multi-core, its core id is 0. 3) thread_siblings: Just include itself, if the cpu doesn't support HT/multi-thread. 4) core_siblings: Just include itself, if the cpu doesn't support multi-core and HT/Multi-thread. So be careful when declaring the 4 defines in include/asm-XXX/topology.h. If an attribute isn't defined on an architecture, it won't be exported. Thank Nathan, Greg, Andi, Paul and Venki.

They are not removable (as defined by Linux) as the media and device are inseparable. When a card is removed, the whole device is removed from the system and never sits in a media-less state. This stops some nasty udev device creation/destruction loops. Further, once this change is made, there is no need for ide to can be removed from ide_drive_t.

There seems to be no libata driver (yet), but there is an ide driver, hpt366. When the driver gets loaded, it causes a kernel NULL pointer dereference in pci_bus_clock_list. It seems to be because the driver is waiting for clock stabilization in init_hpt37x() which never comes. The driver just continues on with the pci drvdata set to NULL, instead of a valid clock entry.

This causes it to overflow packet length values of 128KB or more. I changed the field to 32 bits to fix this. The pktcdvd driver defaulted to its maximum allowed packet length when it detected a 0 in the track info field. I changed this to fail the operation and refuse to access the media. This seems more sane than attempting to access it with a value that almost certainly will not work.

This may lead to messages such as dsl0: hw csum failure. Similarly, we need to clear the hardware checksum flag when we use the existing packet to store the decompressed result.
