The pipestat fields affect reporting of all vblank-related interrupts, so we have to reset them during the irq_handler, and while enabling vblank interrupts. Otherwise, if a pipe status field had been set to non-zero before enabling reporting, we would never see an interrupt again. This patch adds i915_enable_pipestat and i915_disable_pipestat to abstract out the steps needed to change the reported interrupts.

The IMR masking was a technique recommended for avoiding getting stuck with no interrupts generated again in MSI mode. It kept new IIR bits from getting set between the IIR read and the IIR write, which would have otherwise prevented an MSI from ever getting generated again. However, this caused a problem for vblank as the IMR mask would keep the pipe event interrupt from getting reflected in IIR, even after the IMR mask was brought back down. Instead, just check the state of IIR after we ack the interrupts we're going to handle, and restart if we didn't get IIR all the way to zero.

Looks like lcd_sx1.c never got converted, and now it breaks builds. It seems the lcd_sx1.c driver is attempting SPI mode, but doing it in a different way compared to omap_mcbsp_set_spi_mode(). Remove the broken driver, patches welcome to add it back when done properly by patching both mcbsp.c and lcd_sx1.c.

Wysocki" Date: Wed, 26 Nov 2008 17:53:13 -0500 Subject: ACPI suspend: Blacklist boxes that require us to set SCI_EN directly on resume Some Apple boxes evidently require us to set SCI_EN on resume directly, because if we don't do that, they hung somewhere in the resume code path. Moreover, on these boxes it is not sufficient to use acpi_enable() to turn ACPI on during resume. All of this is against the ACPI specification which states that (1) the BIOS is supposed to return from the S3 sleep state with ACPI enabled (SCI_EN set) and (2) the SCI_EN bit is owned by the hardware and we are not supposed to change it. For this reason, blacklist the affected systems so that the SCI_EN bit is set during resume on them. [NOTE: Unconditional setting SCI_EN for all system on resume doesn't work, because it makes some other systems crash (that's to be expected). Also, it is not entirely clear right now if all of the Apple boxes require this workaround.] This patch fixes the recent regression tracked as http://bugzilla.kernel.org/show_bug.cgi?id=12038 Signed-off-by: Rafael J.

It is possible for fan_suspend() to fail to properly initialize fan_control_desired_level as required by fan_resume(), resulting on the fan always being set to level 7 on resume if the user didn't touch the fan controller. In order to get fan sleep/resume handling to work right: 1. Fix the fan_suspend handling of the T43 firmware quirk. If it is still undefined, we didn't touch the fan yet and that means we have no business doing it on resume. 2. Store the fan level on its own variable to avoid any possible issues with hijacking fan_control_desired_level (which isn't supposed to have anything other than 0-7 in it, anyway). 3. Change the fan_resume code to me more straightforward to understand (although we DO optimize the boolean logic there, otherwise it looks disgusting). 4. Add comments to help understand what the code is supposed to be doing. 5. Change fan_set_level to be less strict about how auto and full-speed modes are requested. http://bugzilla.kernel.org/show_bug.cgi?id=11982 Signed-off-by: Henrique de Moraes Holschuh Reported-by: Tino Keitel Signed-off-by: Len Brown --- drivers/misc/thinkpad_acpi.c | 57 ++++++++++++++++++++++++++++++++++---------- 1 file changed, 45 insertions(+), 12 deletions(-) (limited to 'drivers') diff --git a/drivers/misc/thinkpad_acpi.c b/drivers/misc/thinkpad_acpi.c index 7a4a26b0edd..899766e16fa 100644 --- a/drivers/misc/thinkpad_acpi.c +++ b/drivers/misc/thinkpad_acpi.c @@ -5318,6 +5318,7 @@ static enum fan_control_commands fan_control_commands; static u8 fan_control_initial_status; static u8 fan_control_desired_level; +static u8 fan_control_resume_level; static int fan_watchdog_maxinterval; static struct mutex fan_mutex; @@ -5440,8 +5441,8 @@ static int fan_set_level(int level) case TPACPI_FAN_WR_ACPI_FANS: case TPACPI_FAN_WR_TPEC: - if ((level != TP_EC_FAN_AUTO) && - (level != TP_EC_FAN_FULLSPEED) && + if (!(level & TP_EC_FAN_AUTO) && + !(level & TP_EC_FAN_FULLSPEED) && ((level < 0) || (level > 7))) return -EINVAL; @@ -6005,38 +6006,67 @@ static void fan_exit(void) static void fan_suspend(pm_message_t state) { + int rc; + if (!fan_control_allowed) return; /* Store fan status in cache */ - fan_get_status_safe(NULL); + fan_control_resume_level = 0; + rc = fan_get_status_safe(&fan_control_resume_level); + if (rc < 0) + printk(TPACPI_NOTICE + "failed to read fan level for later " + "restore during resume: %d\n", rc); + + /* if it is undefined, don't attempt to restore it. + * KEEP THIS LAST */ if (tp_features.fan_ctrl_status_undef) - fan_control_desired_level = TP_EC_FAN_AUTO; + fan_control_resume_level = 0; } static void fan_resume(void) { - u8 saved_fan_level; u8 current_level = 7; bool do_set = false; + int rc; /* DSDT *always* updates status on resume */ tp_features.fan_ctrl_status_undef = 0; - saved_fan_level = fan_control_desired_level; if (!fan_control_allowed || + !fan_control_resume_level || (fan_get_status_safe(¤t_level) < 0)) return; switch (fan_control_access_mode) { case TPACPI_FAN_WR_ACPI_SFAN: - do_set = (saved_fan_level > current_level); + /* never decrease fan level */ + do_set = (fan_control_resume_level > current_level); break; case TPACPI_FAN_WR_ACPI_FANS: case TPACPI_FAN_WR_TPEC: - do_set = ((saved_fan_level & TP_EC_FAN_FULLSPEED) || - (saved_fan_level == 7 && - !(current_level & TP_EC_FAN_FULLSPEED))); + /* never decrease fan level, scale is: + * TP_EC_FAN_FULLSPEED > 7 >= TP_EC_FAN_AUTO + * + * We expect the firmware to set either 7 or AUTO, but we + * handle FULLSPEED out of paranoia. + * + * So, we can safely only restore FULLSPEED or 7, anything + * else could slow the fan.

This happens because in the blacklist it is declared with HID_USB_DEVICE although the keyboards are really bluetooth devices. The same holds for 'apple_devices' list. This patch fixes it by changing HID_USB_DEVICE to HID_BLUETOOTH_DEVICE in those two lists.

More interesting, in the same failure case handling, it calls the exit function, which also frees the rfkill state, but after stopping the polling. If the race happens, a NULL pointer is passed to rfkill_force_state() which then causes a nice dereference. Fix the race by just not doing the too-early freeing of the rfkill state. This appears to be the cause of a hot issue on kerneloops.org; while I have no solid evidence of that this patch will fix the issue, the race appears rather real.

As part of that support, SET_PORT is invoked to set the port type during driver startup. However, as a side-effect, for IB ports the invocation of this command also sets the port's capability mask to zero (losing the default value set by FW). To fix this, get the default ib port capabilities (via a MAD_IFC Port Info query) during driver startup, and save them for use in the mlx4_SET_PORT command when setting the port-type to Infiniband. This patch fixes problems with subnet manager (SM) failover such as , which occurred because the IsTrapSupported bit in the capability mask was zeroed.

The panic kernel either does not start at all or crash in various places. The problem is that hpwdt_pretimeout is registered with register_die_notifier() with the highest possible priority. Because it returns NOTIFY_STOP, the crash_nmi_callback which is also registered with register_die_notifier() is never executed. This causes the shutdown of other CPUs to fail. Reverting the order is no option: The crash_nmi_callback executes HLT and so never returns normally. Because of that, it must be executed as last notifier, which currently is done. So, that patch returns NOTIFY_OK to keep the crash_nmi_callback executed.

As a result, if any app used resize CQ repeatedly, all MTTs were eventually exhausted, which led to all memory registration operations failing until the driver is reloaded. Once the RESIZE_CQ command returns successfully from FW, FW no longer accesses the old CQ buffer, so it is safe to deallocate the MTT entries used by the old CQ buffer. Finally, if the RESIZE_CQ command fails, the MTTs allocated for the new CQEs buffer also need to be de-allocated. This fixes .

However this broke the fbcon timeout blanking. If you use a driver that defines ->fb_blank operation and at the same time that driver relies on other driver (e.g. backlight or lcd class) to blank the screen, when the fbcon times out and tries to blank the fb, it will call only fb driver blanker and won't notify the other driver. Thus FB output is disabled, but the screen isn't blanked. Restore fbcon blanking and at the same time apply the proper fix for the above problem: if fbcon_blank is called with FBINFO_FLAG_USEREVENT, we are already called through notification from fb_blank, thus we don't have to blank the fb again.

Also i82975x_edac code seems to have the same module removal bugs as in i82875p_edac. The problems were: 1. In module removal i82875p_remove_one() is never called. Variable i82875p_registered is newer changed from 1, which guarantees i82875p_remove_one() is not called (and even if it were called, it would be called in wrong order). As a result, the edac_mc workque is not stopped and keeps probing. If kernel debugging options are not enabled, user may not notice anything going wrong. if debugging options are enabled and I do "rmmod i82875p_edac", I get: edac debug: edac_pci_workq_function() checking BUG: unable to handle kernel paging request at f882d16f ... call trace: [] ? edac_mc_workq_function+0x55/0x7e [edac_core] [] ? run_workqueue+0xd7/0x1a5 [] ? run_workqueue+0x92/0x1a5 [] ? edac_mc_workq_function+0x0/0x7e [edac_core] [] ? worker_thread+0xb7/0xc3 [] ? autoremove_wake_function+0x0/0x33 [] ? worker_thread+0x0/0xc3 [] ? kthread+0x3b/0x61 [] ? kthread+0x0/0x61 [] ? kernel_thread_helper+0x7/0x10 Fix for this is to get rid of needles variable i82875p_registered altogether and run i82875p_remove_one() *before* pci_unregister_driver(). 2. edac_mc_del_mc() uses mci after freeing mci edac_mc_del_mc() calls calls edac_remove_sysfs_mci_device(). The kobject refcount of mci drops to 0 and mci is freed. After this mci is accessed via debug print and i82875p_remove_one() still uses mci->pvt and tries to free mci again with edac_mc_free(). The fix for this is add kobject_get(&mci->edac_mci_kobj) after edac_mc_alloc(). Then the mci is still available after returning from edac_mc_del_mc() with refcount 1, and mci->pvt is still available. When i82875p_remove_one() finally calls edac_mc_free(), this will cause kobject_put() and mci is released properly.

In order to achieve this: * Add ide_pci_is_in_compatibility_mode() inline helper to . * Add IDE_HFLAG_BROKEN_ALTSTATUS host flag and set it in amd74xx host driver for nVidia controllers in Compatibility Mode. * Teach actual_try_to_identify() and drive_is_ready() about the new flag. This fixes the regression caused by removal of CONFIG_IDEPCI_SHARE_IRQ config option in 2.6.25 and using AltStatus register unconditionally when available (kernel.org bugs #11659 and #10216). [ Moreover for CONFIG_IDEPCI_SHARE_IRQ=y (which is what most people and distributions use) it never worked correctly. ] Thanks to Remy LABENE and Lars Winterfeld for help with debugging the problem.
