2014-09-18drm/radeon/TN: only enable bapm on MSI systemsAlex Deucher
commit 730a336c33a3398d65896e8ee3ef9f5679fe30a9 upstream. There still seem to be stability problems with other systems. Bug: https://bugs.freedesktop.org/show_bug.cgi?id=72921 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Jiri Slaby <jslaby@suse.cz>
2014-09-18drm/radeon: enable bapm by default on desktop TN/RL boardsAlex Deucher
commit 0c78a44964db3d483b0c09a8236e0fe123aa9cfc upstream. bapm enabled the GPU and CPU to share TDP headroom. It was disabled by default since some laptops hung when it was enabled in conjunction with dpm. It seems to be stable on desktop boards and fixes hangs on boot with dpm enabled on certain boards, so enable it by default on desktop boards. bug: https://bugs.freedesktop.org/show_bug.cgi?id=72921 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Jiri Slaby <jslaby@suse.cz>
2014-09-18drm/i915: read HEAD register back in init_ring_common() to enforce orderingJiri Kosina
commit ece4a17d237a79f63fbfaf3f724a12b6d500555c upstream. Withtout this, ring initialization fails reliabily during resume with [drm:init_ring_common] *ERROR* render ring initialization failed ctl 0001f001 head ffffff8804 tail 00000000 start 000e4000 This is not a complete fix, but it is verified to make the ring initialization failures during resume much less likely. We were not able to root-cause this bug (likely HW-specific to Gen4 chips) yet. This is therefore used as a ducttape before problem is fully understood and proper fix created, so that people don't suffer from completely unusable systems in the meantime.

2014-09-18drm/ttm: Pass GFP flags in order to avoid deadlock.Tetsuo Handa
commit a91576d7916f6cce76d30303e60e1ac47cf4a76d upstream. Commit 7dc19d5a "drivers: convert shrinkers to new count/scan API" added deadlock warnings that ttm_page_pool_free() and ttm_dma_page_pool_free() are currently doing GFP_KERNEL allocation. But these functions did not get updated to receive gfp_t argument. This patch explicitly passes sc->gfp_mask or GFP_KERNEL to these functions, and removes the deadlock warning.

2014-09-18drm/ttm: Fix possible stack overflow by recursive shrinker calls.Tetsuo Handa
commit 71336e011d1d2312bcbcaa8fcec7365024f3a95d upstream. While ttm_dma_pool_shrink_scan() tries to take mutex before doing GFP_KERNEL allocation, ttm_pool_shrink_scan() does not do it. This can result in stack overflow if kmalloc() in ttm_page_pool_free() triggered recursion due to memory pressure. shrink_slab() => ttm_pool_shrink_scan() => ttm_page_pool_free() => kmalloc(GFP_KERNEL) => shrink_slab() => ttm_pool_shrink_scan() => ttm_page_pool_free() => kmalloc(GFP_KERNEL) Change ttm_pool_shrink_scan() to do like ttm_dma_pool_shrink_scan() does.

2014-09-18drm/ttm: Use mutex_trylock() to avoid deadlock inside shrinker functions.Tetsuo Handa
commit 22e71691fd54c637800d10816bbeba9cf132d218 upstream. I can observe that RHEL7 environment stalls with 100% CPU usage when a certain type of memory pressure is given. While the shrinker functions are called by shrink_slab() before the OOM killer is triggered, the stall lasts for many minutes. One of reasons of this stall is that ttm_dma_pool_shrink_count()/ttm_dma_pool_shrink_scan() are called and are blocked at mutex_lock(&_manager->lock). GFP_KERNEL allocation with _manager->lock held causes someone (including kswapd) to deadlock when these functions are called due to memory pressure. This patch changes "mutex_lock();" to "if (!mutex_trylock()) return ...;" in order to avoid deadlock.

commit 46c2df68f03a236b30808bba361f10900c88d95e upstream. We can use "unsigned int" instead of "atomic_t" by updating start_pool variable under _manager->lock.

2014-09-03drm: omapdrm: fix compiler errorsRussell King
commit 2d31ca3ad7d5d44c8adc7f253c96ce33f3a2e931 upstream. Regular randconfig nightly testing has detected problems with omapdrm. omapdrm fails to build when the kernel is built to support 64-bit DMA addresses and/or 64-bit physical addresses due to an assumption about the width of these types. Use %pad to print DMA addresses, rather than %x or %Zx (which is even more wrong than %x). Avoid passing a uint32_t pointer into a function which expects dma_addr_t pointer. drivers/gpu/drm/omapdrm/omap_plane.c: In function 'omap_plane_pre_apply': drivers/gpu/drm/omapdrm/omap_plane.c:145:2: error: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t' [-Werror=format] drivers/gpu/drm/omapdrm/omap_plane.c:145:2: error: format '%x' expects argument of type 'unsigned int', but argument 6 has type 'dma_addr_t' [-Werror=format] make[5]: *** [drivers/gpu/drm/omapdrm/omap_plane.o] Error 1 drivers/gpu/drm/omapdrm/omap_gem.c: In function 'omap_gem_get_paddr': drivers/gpu/drm/omapdrm/omap_gem.c:794:4: error: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'dma_addr_t' [-Werror=format] drivers/gpu/drm/omapdrm/omap_gem.c: In function 'omap_gem_describe': drivers/gpu/drm/omapdrm/omap_gem.c:991:4: error: format '%Zx' expects argument of type 'size_t', but argument 7 has type 'dma_addr_t' [-Werror=format] drivers/gpu/drm/omapdrm/omap_gem.c: In function 'omap_gem_init': drivers/gpu/drm/omapdrm/omap_gem.c:1470:4: error: format '%x' expects argument of type 'unsigned int', but argument 7 has type 'dma_addr_t' [-Werror=format] make[5]: *** [drivers/gpu/drm/omapdrm/omap_gem.o] Error 1 drivers/gpu/drm/omapdrm/omap_dmm_tiler.c: In function 'dmm_txn_append': drivers/gpu/drm/omapdrm/omap_dmm_tiler.c:226:2: error: passing argument 3 of 'alloc_dma' from incompatible pointer type [-Werror] make[5]: *** [drivers/gpu/drm/omapdrm/omap_dmm_tiler.o] Error 1 make[5]: Target `__build' not remade because of errors. make[4]: *** [drivers/gpu/drm/omapdrm] Error 2 Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Dave Airlie <airlied@redhat.com> Signed-off-by: Jiri Slaby <jslaby@suse.cz>

2014-06-20drm/i915: Allow user modes to exceed DVI 165MHz limitVille Syrjälä
commit 40478455fefdc0bde24ae872c3f88d58a1b0e435 upstream. In commit commit 6375b768a9850b6154478993e5fb566fa4614a9c Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Mon Mar 3 11:33:36 2014 +0200 drm/i915: Reject >165MHz modes w/ DVI monitors the driver started to filter out display modes which exceed the single-link DVI 165Mz dotclock limits when the monitor doesn't report itself as being HDMI compliant. The intent was to filter out all EDID derived modes that require dual-link DVI to operate since we don't support dual-link. However the patch went a bit too far and also causes the driver to reject such modes even when specified by the user. Normally we don't check the sink limitations when setting a mode from the user. This allows the user to specify any mode whether the sink reports to support it or not. This can be useful since often the sinks support more modes than they report in the EDID. So relax the checks a bit, and apply the single-link DVI dotclock limit only when filtering the mode list, and ignore the limit when setting a user specified mode.

2014-06-20drm/i915: Only copy back the modified fields to userspace from execbufferChris Wilson
commit 9aab8bff7aa3bee567213ad3c1fdfb217bb980a2 upstream. We only want to modifiy a single field in the userspace view of the execbuffer command buffer, so explicitly change that rather than copy everything back again. This serves two purposes: 1. The single fields are much cheaper to copy (constant size so the copy uses special case code) and much smaller than the whole array. 2. We modify the array for internal use that need to be masked from the user. Note: We need this backported since without it the next bugfix will blow up when userspace recycles batchbuffers and relocations.

2014-06-18drm/i915: restrict vt-d stolen memory workaround to pre-gen8Daniel Vetter
commit fcc9fe1a5ad2b826c6ac58c03cdc0cf17a63c7a1 upstream. We want future generations to at least attempt to use all features, so restrict the stolen memory disabling when vt-d is enabled to the latest generation we have reports for. Which is a HSW per the original report. Also once we get a bit a hold of some of the mysterious framebuffer in stolen memory issues that still haunt bugzilla, we should probably drop this hack again and see what happens.

2014-06-09drm/i915: Fix unsafe loop iteration over vma whilst unbinding themChris Wilson
This is commit df6f783a4ef6790780a67c491897ac upstream. On non-LLC platforms, when changing the cache level of an object, we may need to unbind it so that prefetching across page boundaries does not cross into a different memory domain. This requires us to unbind conflicting vma, but we did so iterating over the objects vma in an unsafe manner (as the list was being modified as we iterated).

This is commit 2ab1bc9df01dbc19b55b2271100db7 upstream. Apparently it doesn't work. X-tiled self-refresh works flawlessly otoh. Apparently X still works correctly with linear framebuffers, so might just be an issue with the initial modeset. It's unclear whether this just borked wm setup from our side or a hw restriction, but just disabling gets things going.
