2011-11-11PCI: pciehp: wait 1000 ms before Link Training checkKenji Kaneshige
We need to wait for 1000 ms after Data Link Layer Link Active (DLLLA) bit reads 1b before sending configuration request. Currently pciehp does this wait after checking Link Training (LT) bit. But we need it before checking LT bit because LT is still set even after DLLLA bit is set on some platforms.

2011-11-11mwifiex: fix association issue with AP configured in hidden SSID modeAmitkumar Karwar
Firmware expects 'max_ssid_length' field in 'struct mwifiex_ie_types_wildcard_ssid_params' to be '0' for performing SSID specific scan. Currently driver updates it with an actual SSID length. Hence UUT is not able to find the AP configured in hidden SSID mode in scan results and association fails. max_ssid_length is filled with '0' to fix the issue.

2011-11-11iwlwifi: avoid a panic when unloading the module with RF KillEmmanuel Grumbach
When HW RF kill switch is set to kill the radio, our NIC issues an interrupt after we stop the APM module. When we unload the module, the driver disables and cleans the interrupts before stopping the APM. So we have a real interrupt (inta not zero) pending. When this interrupts pops up the tasklet has already been killed and we crash. Here is a logical description of the flow: disable and clean interrupts synchronize interrupts kill the tasklet stop the APM <<== creates an RF kill interrupt free_irq <<== somehow our ISR is called here and we crash Here is the panic message: [ 201.313636] BUG: unable to handle kernel paging request at ffff8800911b7150 [ 201.314541] IP: [<ffffffff8106d652>] tasklet_action+0x62/0x130 [ 201.315149] PGD 1c06063 PUD db37f067 PMD db408067 PTE 80000000911b7160 [ 201.316456] Oops: 0000 [#1] SMP DEBUG_PAGEALLOC [ 201.317324] CPU 1 [ 201.317495] Modules linked in: arc4 iwlwifi(-) mac80211 cfg80211 netconsole configfs binfmt_misc i915 drm_kms_helper drm uvcvideo i2c_algo_bit videodev dell_laptop dcdbas intel_agp dell_wmi intel_ips psmouse intel_gtt v4l2_compat_ioctl32 asix usbnet mii serio_raw video sparse_keymap firewire_ohci sdhci_pci sdhci firewire_core e1000e crc_itu_t [last unloaded: configfs] [ 201.323839] [ 201.324015] Pid: 2061, comm: modprobe Not tainted 3.1.0-rc9-wl #4 Dell Inc.

2011-11-11[SCSI] aacraid: controller hangs if kernel uses non-default ASPM policyVasily Averin
Aacraid controller can hang on some nodes if kernel uses non-default (powersave) ASPM policy. Controller hangs shortly after successful load and hardware detection. Scsi error handler detects this hang and tries to restart hardware but it does not help. Initially it was noticed on RHEL6-based openVZ kernel after backporting aacraid driver from mainline (RHEL6 kernel with original driver works well) http://bugzilla.openvz.org/show_bug.cgi?id=2043 This issue happens because default ASPM policy was changed in Red Hat kernels. Therefore guys from Red Hat have noticed this problem long time ago: on Fedora 12 https://bugzilla.redhat.com/show_bug.cgi?id=540478 on Fedora 14 https://bugzilla.redhat.com/show_bug.cgi?id=679385 In RHEL6 kernel this issue was fixed, ASPM was disabled in aacraid driver. In kernel changelog I've found that seems it was done by Matthew Garrett: - [scsi] aacraid: Disable ASPM by default (Matthew Garrett) [599735] However seems this patch was not submitted to mainline. I've reproduced this issue on vanilla 3.1.0 kernel booted with "pcie_aspm.policy=powersave" option, So I believe it makes sense to do it now.

2011-11-11drm: do not sleep on vblank while holding a mutexIlija Hadzic
drm_wait_vblank must be DRM_UNLOCKED because otherwise it will grab the drm_global_mutex and then go to sleep until the vblank event it is waiting for. That can wreck havoc in the windowing system because if one process issues this ioctl, it will block all other processes for the duration of all vblanks between the current and the one it is waiting for. In some cases it can block the entire windowing system. v2: incorporate comments received from Daniel Vetter and Michel Daenzer. v3/v4: after a lengty discussion with Daniel Vetter, it was concluded that the only thing not yet protected with locks and atomic ops is the write to dev->last_vblank_wait. It's only used in a debug file in proc, and the current code already employs no correct locking: the proc file only takes dev->struct_mutex, whereas drm_wait_vblank implicitly took the drm_global_mutex. Given all this, it's not worth bothering to try to fix the locks at this time.

2011-11-11drm/radeon: Make sure CS mutex is held across GPU reset.Michel Dänzer
This was only the case if the GPU reset was triggered from the CS ioctl, otherwise other processes could happily enter the CS ioctl and wreak havoc during the GPU reset. This is a little complicated because the GPU reset can be triggered from the CS ioctl, in which case we're already holding the mutex, or from other call paths, in which case we need to lock the mutex. AFAICT the mutex API doesn't allow recursive locking or finding out the mutex owner, so we need to handle this with helper functions which allow recursive locking from the same process.

2011-11-11drivers: sh: Generalize runtime PM platform stub.Paul Mundt
The runtime PM platform support stub in use by ARM-based SH/R-Mobile platforms contains nothing that's specifically ARM-related and instead of wholly generic to anything using the clock framework. The recent runtime PM changes interact rather badly with the lazy disabling of clocks late in the boot process through the clock framework, leading to situations where the runtime suspend/resume paths are entered without a clock being actively driven due to having been lazily gated off. In order to correct this we can trivially tie in the aforementioned stub as a general fallback for all SH platforms that don't presently have their own runtime PM implementations (the corner case being SH-based SH-Mobile platforms, which have their own stub through the hwblk API -- which in turn has bitrotted and will be subsequently adapted to use the same stub as everyone else), regardless of whether the platforms choose to define power domains of their own or not. This fixes up regressions for clock framework users who also build in runtime PM support without any specific power domains of their own, which was previously causing the serial console to be lost when warring with lazy clock disabling.

Refrain from running clk_disable() on clocks that have not been enabled. A typical case when this can happen is during Suspend-to-RAM for devices that have no driver associated with them. In such case the clock may be in default ACQUIRED state. Without this patch the sh7372 Mackerel board crashes in __clk_disable() during Suspend-to-RAM with: "Trying to disable clock 0xdeadbeef with 0 usecount" This happens for the CEU device which is added during boot. The test case has no CEU driver included in the kernel configuration. Needed for v3.2-rc1. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

2011-11-10drm/nouveau: by default use low bpp framebuffer on low memory cardsMarcin Slusarz
Framebuffer's BPP is not that important but can waste significant part of memory on low-VRAM cards. Lower it to 8bpp on < 32MB cards and to 16bpp on 64MB cards. It can still be overridden by video= option. Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2011-11-10drm/nvc0/gr: fix some bugs in grctx generationBen Skeggs
Most serious is for chips with only 1 TPC, we'd get stuck in an infinite loop. The fix here will slightly change the setup for all other chipsets too, but, it shouldn't matter too much, and this all needs figuring out and likely redone anyway. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
