| | * drm/amdgpu: use post-decrement in error handlingRasmus Villemoes2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 09ccbb74b6718ad4d1290de3f5669212c0ac7d4b upstream. We need to use post-decrement to get the pci_map_page undone also for i==0, and to avoid some very unpleasant behaviour if pci_map_page failed already at i==0.

Otherwise we could try to evict overlapping userptr BOs in get_user_pages(), leading to a possible circular locking dependency.

| | * drm/amdgpu: hold reference to fences in amdgpu_sa_bo_new (v2)Nicolai Hähnle2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit a8d81b36267366603771431747438d18f32ae2d5 upstream. An arbitrary amount of time can pass between spin_unlock and fence_wait_any_timeout, so we need to ensure that nobody frees the fences from under us. A stress test (rapidly starting and killing hundreds of glxgears instances) ran into a deadlock in fence_wait_any_timeout after about an hour, and this race condition appears to be a plausible cause. v2: agd: rebase on upstream Signed-off-by: Nicolai Hähnle <nicolai.haehnle@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

When the framebuffer is a vmwgfx dma buffer and a proxy surface is created, the vmw_kms_update_proxy() function requires that the proxy surface width and the framebuffer pitch are compatible, otherwise display corruption occurs as seen in gnome-shell/native with software 3D. Since the framebuffer pitch is determined by user-space, allocate a proxy surface the width of which is based on the framebuffer pitch rather than on the framebuffer width.

While doing so make sure we dont do that when already in zero order pool. For zero order(pool_idx = 0) pool, (pool_idx-1) value becomes -1 that is invalid and compiler throws the error that array subscript is below bounds. This problem is exposed when we enable kernel config option "CONFIG_ALLOC_BUFFERS_IN_4K_CHUNKS" which will force only zero order pool and hence the index value calculation to -1.

* | msm: kgsl: Add 1M and 8K pools to the allocatorShrenuj Bansal2016-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change includes the below: - Add 1M and 8k pools and structure the allocator to use all pools from the largest page to the smallest - Reserve a set number of pages for each of these pools at init time - When allocating, use the reserved pools and then fall back to allocating from system memory using only 8k and 4k pages - Remove maximums on the pool sizes - Zero the memory when we create the pool initially and add pages back to the pool on free CRs-Fixed: 995735 Change-Id: I9440bad62d3e13b434902f167c9d23467b1c4235 Signed-off-by: Shrenuj Bansal <shrenujb@codeaurora.org>
* | msm: kgsl: Remove harmless preemption log messageHarshdeep Dhatt2016-05-05
| | | | | | | | | | | | | | | | | | | | | | | | This message is logged when we receive a preemption interrupt after we have already detected that preemption has been finished in hardware by reading the preemption status register. This is a harmless condition so remove it. CRs-Fixed: 993480 Change-Id: I61a48353428b3faa042fbc85e259b33c7f23bdb0 Signed-off-by: Harshdeep Dhatt <hdhatt@codeaurora.org>
* | msm: kgsl: Fix overflow in sharedmem read/write functionsSunil Khatri2016-05-05
| | | | | | | | | | | | | | | | | | | | There could be possibility of integer overflow on adding sizeof(uint32_t) with uint64_t maximum offset bytes and result in a value smaller than uint64_t maximum memdesc size.

| | | | | | | | | | | | | | | | | | | | Dumping only the ctxt_record structure in a snapshot is not enough. For a more meaningful snapshot, dump 64KB of preempt record. Also, move the code to device specific snapshot function. Change-Id: I43e08ccefbf2d3911191b2aad5168979956e1626 Signed-off-by: Harshdeep Dhatt <hdhatt@codeaurora.org>

| | | | | | | | | | | | | | | | | | When the IOCTL is called with invalid data, don't log to kmsg. The returned error code should be enough to tell the UMD what they did wrong.

* | msm: kgsl: Remove superfluous NULL checks when reading timestampsCarter Cooper2016-05-05
| | | | | | | | | | | | | | | | | | There is no way for the UMD to pass in NULL pointers for reading timestamps. The KGSL driver also always has valid pointers for storing the readpointer. Remove the checks that are not needed. Change-Id: Id5f244a57a2b991a10b603ef7236193d4282fd0f Signed-off-by: Carter Cooper <ccooper@codeaurora.org>

* | msm: kgsl: Use a page pool to reduce allocation timeDeepak Kumar2016-05-05
| | | | | | | | | | | | | | | | | | | | | | Use a mempool to reduce the allocation time. When memory allocated from pages is freed, put it in a page pool. At allocation time, try to allocate from the page pool before getting pages from the system. Make sure that the pool does not grow too big by enforcing a maximum limit.
