2005-11-10[PATCH] PCI: automatically set device_driver.ownerLaurent riffard
A nice feature of sysfs is that it can create the symlink from the driver to the module that is contained in it. It requires that the device_driver.owner is set, what is not the case for many PCI drivers. This patch allows pci_register_driver to set automatically the device_driver.owner for any PCI driver. Credits to Al Viro who suggested the method.

2005-11-10[PATCH] pciehp: fix handling of power faults during hotplugrajesh.shah@intel.com
The current pciehp implementation reports a power-fail error even if the condition has cleared by the time the corresponding interrupt handling code gets a chance to run.

2005-11-10[PATCH] pciehp: clean-up how we request control of hotplug hardwarerajesh.shah@intel.com
This patch further tweaks how we request control of hotplug controller hardware from BIOS. We first search the ACPI namespace corresponding to a specific hotplug controller looking for an _OSC or OSHP method. On failure, we successively move to the ACPI parent object, till we hit the highest level host bridge in the hierarchy. This allows for different types of BIOS's which place the _OSC/OSHP methods at various places in the acpi namespace, while still not encroaching on the namespace of some other root level host bridge. This patch also introduces a new load time option (pciehp_force) that allows us to bypass all _OSC/OSHP checking. Not supporting these methods seems to be be the most common ACPI firmware problem we've run into. This will still _not_ allow the pciehp driver to work correctly if the BIOS really doesn't support pciehp (i.e. if it doesn't generate a hotplug interrupt). Use this option with caution. Some BIOS's may deliberately not build any _OSC/OSHP methods to make sure it retains control the hotplug hardware. Using the pciehp_force parameter for such systems can lead to two separate entities trying to control the same hardware.

2005-11-10[PATCH] pciehp: request control of each hotplug controller individuallyrajesh.shah@intel.com
This patch tweaks the way pciehp requests control of the hotplug hardware from BIOS. It now tries to invoke the ACPI _OSC method for a specific hotplug controller only, rather than walking the entire acpi namespace invoking all possible _OSC methods under all host bridges. This allows us to gain control of each hotplug controller individually, even if BIOS fails to give us control of some other hotplug controller in the system.

2005-11-10[PATCH] pciehp: remove redundant data structuresrajesh.shah@intel.com
State information is currently stored in per-slot as well as per-pci-function data structures in pciehp. There's a lot of overlap in the information kept, and some of it is never used. This patch consolidates the state information to per-slot and eliminates unused data structures. The biggest change is to eliminate the pci_func structure and the code around managing its lists.

2005-11-10[PATCH] pciehp: reduce dependence on ACPIrajesh.shah@intel.com
Reduce the PCI Express hotplug driver's dependence on ACPI. We don't walk the acpi namespace anymore to build a list of bridges and devices. We go to ACPI only to run the _OSC or _OSHP methods to transition control of hotplug hardware from system BIOS to the hotplug driver, and to run the _HPP method to get hotplug device parameters like cache line size, latency timer and SERR/PERR enable from BIOS. Note that one of the side effects of this patch is that pciehp does not automatically enable the hot-added device or its DMA bus mastering capability now. It expects the device driver to do that. This may break some drivers and we will have to fix them as they are reported. Signed-off-by: Rajesh Shah <rajesh.shah@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-11-10[PATCH] patch 1/8] pciehp: use the PCI core for hotplug resource managementrajesh.shah@intel.com

2005-11-10[PATCH] PCI: add pci_find_next_capability()Roland Dreier
Some devices have more than one capability of the same type. For example, the PCI header for the PathScale InfiniPath looks like: 04:01.0 InfiniBand: Unknown device 1fc1:000d (rev 02) Subsystem: Unknown device 1fc1:000d Flags: bus master, fast devsel, latency 0, IRQ 193 Memory at fea00000 (64-bit, non-prefetchable) [size=2M] Capabilities: [c0] HyperTransport: Slave or Primary Interface Capabilities: [f8] HyperTransport: Interrupt Discovery and Configuration There are _two_ HyperTransport capabilities, and the PathScale driver wants to look at both of them. The current pci_find_capability() API doesn't work for this, since it only allows us to get to the first capability of a given type. The patch below introduces a new pci_find_next_capability(), which can be used in a loop like for (pos = pci_find_capability(pdev, <ID>); pos; pos = pci_find_next_capability(pdev, pos, <ID>)) { /* ... */ } Signed-off-by: Roland Dreier <rolandd@cisco.com> Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2005-11-10[NET]: Detect hardware rx checksum faults correctlyHerbert Xu
Here is the patch that introduces the generic skb_checksum_complete which also checks for hardware RX checksum faults. If that happens, it'll call netdev_rx_csum_fault which currently prints out a stack trace with the device name. In future it can turn off RX checksum. I've converted every spot under net/ that does RX checksum checks to use skb_checksum_complete or __skb_checksum_complete with the exceptions of: * Those places where checksums are done bit by bit. These will call netdev_rx_csum_fault directly. * The following have not been completely checked/converted: ipmr ip_vs netfilter dccp This patch is based on patches and suggestions from Stephen Hemminger and David S.

2005-11-10[PATCH] kbuild: build breaks after -imacros was introducedZachary Amsden
I have to revert the recent addition of -imacros to the Makefile to get my tool chain to build. Without the change, below, I get: Note that this looks entirely like a toolchain bug. Here is the offending command: [pid 12163] execve("/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/tradcpp0", ["/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/tradcpp0", "-lang-asm", "-nostdinc", "-Iinclude", "-Iinclude/asm-i386/mach-default", "-D__GNUC__=3", "-D__GNUC_MINOR__=2", "-D__GNUC_PATCHLEVEL__=2", "-D__GXX_ABI_VERSION=102", "-D__ELF__", "-Dunix", "-D__gnu_linux__", "-Dlinux", "-D__ELF__", "-D__unix__", "-D__gnu_linux__", "-D__linux__", "-D__unix", "-D__linux", "-Asystem=posix", "-D__NO_INLINE__", "-D__STDC_HOSTED__=1", "-Acpu=i386", "-Amachine=i386", "-Di386", "-D__i386", "-D__i386__", "-D__tune_i386__", "-D__KERNEL__", "-D__ASSEMBLY__", "-isystem", "/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/include", "-imacros", "include/linux/autoconf.h", "-MD", "arch/i386/kernel/.entry.o.d", "arch/i386/kernel/entry.S", "-o", "/tmp/ccOlsFJR.s"] Which should execute properly, I think. But it does not: zach-dev:linux-2.6.14-zach-work $ make CHK include/linux/version.h CHK include/linux/compile.h CHK usr/initramfs_list AS arch/i386/kernel/entry.o /usr/lib/gcc-lib/i386-redhat-linux/3.2.2/tradcpp0: output filename specified twice make[1]: *** [arch/i386/kernel/entry.o] Error 1 make: *** [arch/i386/kernel] Error 2 gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5) Deprecating the -imacros fixes the build for me. It does not appear to be a simple argument overflow problem in trapcpp0, since deprecating all the defines reproduces the problem as well. Also, switching -imacros to -include fixes the problem.

Move the computation of QP capabilities (max scatter/gather entries, max inline data, etc) into the kernel, and have the uverbs module return the values as part of the create QP response. This keeps precise knowledge of device limits in the low-level kernel driver.

2005-11-10[IB] umad: avoid potential deadlock when unregistering MAD agentsRoland Dreier
ib_unregister_mad_agent() completes all pending MAD sends and waits for the agent's send_handler routine to return. umad's send_handler() calls queue_packet(), which does down_read() on the port mutex to look up the agent ID. This means that the port mutex cannot be held for writing while calling ib_unregister_mad_agent(), or else it will deadlock. This patch fixes all the calls to ib_unregister_mad_agent() in the umad module to avoid this deadlock. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-11-10[IPoIB] add path record information in debugfsRoland Dreier
Add ibX_path files to debugfs that contain information about the IPoIB path cache. IPoIB ARP only gives GIDs, which the IPoIB driver must resolve to real IB paths through the ib_sa module.

Also clean up the formatting of the existing _mcg debugfs files. Signed-off-by: Roland Dreier <rolandd@cisco.com>
