2013-09-19drm/fb-helper: don't sleep for screen unblank when an oops is in progressDaniel Vetter
Otherwise the system will burn even brighter and worse, leave the user wondering what's going on exactly. Since we already have a panic handler which will (try) to restore the entire fbdev console mode, we can just bail out. Inspired by a patch from Konstantin Khlebnikov. The callchain leading to this, cut&pasted from Konstantin's original patch: callstack: panic() bust_spinlocks(1) unblank_screen() vc->vc_sw->con_blank() fbcon_blank() fb_blank() info->fbops->fb_blank() drm_fb_helper_blank() drm_fb_helper_dpms() drm_modeset_lock_all() mutex_lock(&dev->mode_config.mutex) Note that the entire locking in the fb helper around panic/sysrq and kdbg is ... non-existant. So we have a decent change of blowing up everything. But since reworking this ties in with funny concepts like the fbdev notifier chain or the impressive things which happen around console_lock while oopsing, I'll leave that as an exercise for braver souls than me.

2013-09-19drm/ttm: fix the tt_populated check in ttm_tt_destroy()Ben Skeggs
After a vmalloc failure in ttm_dma_tt_alloc_page_directory(), ttm_dma_tt_init() will call ttm_tt_destroy() to cleanup, and end up inside the driver's unpopulate() hook when populate() has never yet been called. On nouveau, the first issue to be hit because of this is that dma_address[] may be a NULL pointer. After working around this, ttm_pool_unpopulate() may potentially hit the same issue with the pages[] array. It seems to make more sense to avoid calling unpopulate on already unpopulated TTMs than to add checks to all the implementations.

2013-09-11drm/radeon/atom: workaround vbios bug in transmitter table on rs880 (v2)Alex Deucher
The OUTPUT_ENABLE action jumps past the point in the coder where the data_offset is set on certain rs780 cards. This worked previously because the OUTPUT_ENABLE action is always called immediately after the ENABLE action so the data_offset remained set. In 6f8bbaf568c7f2c497558bfd04654c0b9841ad57 (drm/radeon/atom: initialize more atom interpretor elements to 0), we explictly reset data_offset to 0 between atom calls which then caused this to fail. The fix is to just skip calling the OUTPUT_ENABLE action on the problematic chipsets. The ENABLE action does the same thing and more. Ultimately, we could probably drop the OUTPUT_ENABLE action all together on DCE3 asics. fixes: https://bugzilla.kernel.org/show_bug.cgi?id=60791 v2: only rs880 seems to be affected Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org

2013-09-11drm/radeon: signedness bug in kv_dpm.cDan Carpenter
The problem here is that "unsigned i" is always greater than or equal to zero. These loops mostly have a second check for "(i == 0)" so only the last two are actually buggy. The rest is just cleanup. Bug 1: kv_force_dpm_highest() doesn't have an "(i == 0)" check so it's a potential forever loop. Bug 2: In kv_get_sleep_divider_id_from_clock() there is a typo and the test is reversed "<=" vs ">" so we never enter the loop. That means normally we return KV_MAX_DEEPSLEEP_DIVIDER_ID (5). The return value from here is saved in ->DeepSleepDivId and I wasn't able to determine how that is used. This is a static checker fix and I have not tested it.

2013-09-10i915: bail out earlier when shrinker cannot acquire mutexGlauber Costa
The main shrinker driver will keep trying for a while to free objects if the returned value from the shrink scan procedure is 0. That means "no objects now", but a retry could very well succeed. But what we should say here is a different thing: that it is impossible to shrink, and we would better bail out soon. We find this behavior more appropriate for the case where the lock cannot be taken. Specially given the hammer behavior of the i915: if another thread is already shrinking, we are likely not to be able to shrink anything anyway when we finally acquire the mutex.

2013-09-10drivers: convert shrinkers to new count/scan APIDave Chinner
Convert the driver shrinkers to the new API. Most changes are compile tested only because I either don't have the hardware or it's staging stuff. FWIW, the md and android code is pretty good, but the rest of it makes me want to claw my eyes out. The amount of broken code I just encountered is mind boggling. I've added comments explaining what is broken, but I fear that some of the code would be best dealt with by being dragged behind the bike shed, burying in mud up to it's neck and then run over repeatedly with a blunt lawn mower. Special mention goes to the zcache/zcache2 drivers. They can't co-exist in the build at the same time, they are under different menu options in menuconfig, they only show up when you've got the right set of mm subsystem options configured and so even compile testing is an exercise in pulling teeth. And that doesn't even take into account the horrible, broken code...

git://people.freedesktop.org/~danvet/drm-intel into drm-fixes - Early stolen mem reservation from Jesse in x86 boot code. Acked by Ingo and hpa. This was ready much earlier but somehow I've thought it'd go in through x86 trees, hence why this is late. Avoids the pci resource code to plant mmiobars in the middle of stolen mem and other ugliness. - vgaarb improvements from Alex Williamson plus the fix from Ville for the vgacon->fbcon smooth transition "feature". - Render pageflips on ivb/hsw to avoid stalls due to the ring switching when only flipping on the blitter (Chris). - Deadlock fixes around our flush_workqueue which crept back in - lockdep isn't clever enough :( - Shrinker recursion fix from Chris - this is the thing that blew the vma patches from Ben I've taken out of 3.12. - Fixup for the relocation refactoring. Also an igt testcase to make sure we don't break this again. - Pile of smaller fixups all over, shortlog has full details. * tag 'drm-intel-fixes-2013-09-06' of git://people.freedesktop.org/~danvet/drm-intel: (29 commits) drm/i915: Delay disabling of VGA memory until vgacon->fbcon handoff is done drm/i915: try not to lose backlight CBLV precision drm/i915: Confine page flips to BCS on Valleyview drm/i915: Skip stolen region initialisation if none is reserved drm/i915: fix gpu hang vs. flip stall deadlocks drm/i915: Hold an object reference whilst we shrink it drm/i915: fix i9xx_crtc_clock_get for multiplied pixels drm/i915: handle sdvo input pixel multiplier correctly again drm/i915: fix hpd work vs. flush_work in the pageflip code deadlock drm/i915: fix up the relocate_entry refactoring drm/i915: Fix pipe config warnings when dealing with LVDS fixed mode drm/i915: Don't call sg_free_table() if sg_alloc_table() fails i915: Update VGA arbiter support for newer devices vgaarb: Fix VGA decodes changes vgaarb: Don't disable resources that are not owned drm/i915: Pin pages whilst mapping the dma-buf drm/i915: enable trickle feed on Haswell x86: add early quirk for reserving Intel graphics stolen memory v5 drm/i915: split PCI IDs out into i915_drm.h v4 i915_gem: Convert kmem_cache_alloc(...GFP_ZERO) to kmem_cache_zalloc ...
