2017-07-13drm/amdgpu: Fix KFD oversubscription by tracking queues correctlyJay Cornwall1-1/+1
The number of compute queues available to the KFD was erroneously calculated as 64. Only the first MEC can execute compute queues and it has 32 queue slots. This caused the oversubscription limit to be calculated incorrectly, leading to a missing chained runlist command at the end of an oversubscribed runlist. v2: Remove unused num_mec field to avoid duplicate logic v3: Separate num_mec removal into separate patches Change-Id: I9e7bba2cc1928b624e3eeb1edb06fdb602e5294f Signed-off-by: Jay Cornwall <[email protected]> Reviewed-by: Alex Deucher <[email protected]> Signed-off-by: Oded Gabbay <[email protected]>

2017-07-12drm/i915: use __GFP_RETRY_MAYFAILMichal Hocko1-1/+2
Commit 24f8e00a8a2e ("drm/i915: Prefer to report ENOMEM rather than incur the oom for gfx allocations") has tried to remove disruptive OOM killer because the userspace should be able to cope with allocation failures. At the time only __GFP_NORETRY could achieve that and it turned out that this would fail the allocations just too easily. So "drm/i915: Remove __GFP_NORETRY from our buffer allocator" removed it and hoped for a better solution. __GFP_RETRY_MAYFAIL is that solution. It will keep retrying the allocation until there is no more progress and we would go OOM. Instead we fail the allocation and let the caller to deal with it.

2017-07-11drm: inhibit drm drivers register to uninitialized drm coreAlexandru Moise1-0/+16
If the DRM core fails to init for whatever reason, ensure that no driver ever calls drm_dev_register(). This is best done at drm_dev_init() as it covers drivers that call drm_dev_alloc() as well as drivers that prefer to embed struct drm_device into their own device struct and call drm_dev_init() themselves. In my case I had so many dynamic device majors used that the major number for DRM (226) was stolen, causing DRM core init to fail after failing to register a chrdev, and ultimately calling debugfs_remove() on drm_debugfs_root in drm_core_exit(). After drm core failed to init, VGEM was still calling drm_dev_register(), ultimately leading to drm_debugfs_init(), with drm_debugfs_root passed as the root for the new debugfs dir at debugfs_create_dir(). This led to a kernel panic once we were either derefencing root->d_inode while it was NULL or calling root->d_inode->i_op->lookup() while it was NULL in debugfs at inode_lock() or lookup_*().

And with time slice based scheduler, it waits all the engines become idle before do vGPU switch. So we can run free dispatch in per-ring work_thread, different ring running in different 'vGPU' won't happen. For the workloads between vGPU and Host, this scheduler_mutex can't block host to dispatch workload into other ring engines. Here remove this mutex since it impacts the performance when applications use more than 1 ring engines in 1 vgpu. ring0 running in vGPU1, ring1 running in Host. Will happen. ring0 running in vGPU1, ring1 running in vGPU2. Won't happen.

This reverts commit 62d02fd1f807bf5a259a242c483c9fb98a242630. The rwsem recursive trace should not be fixed from kvmgt side by using a workqueue and it is an issue should be fixed in VFIO. So this one should be reverted. Signed-off-by: Chuanxiao Dong <[email protected]> Cc: Zhenyu Wang <[email protected]> Cc: [email protected] # v4.10+ Signed-off-by: Zhenyu Wang <[email protected]>

It will causes memory leak, if the function setup_spt_oos() fail, in the function intel_gvt_init_gtt(), which allocated by get_zeroed_page() and mapped by dma_map_page(). Unmap and free the page, after STP oos initialize fail, it will fix this issue. Signed-off-by: Zhou, Wenjia <[email protected]> Signed-off-by: Zhenyu Wang <[email protected]>

2017-07-10drm/i915/fbdev: Check for existence of ifbdev->vma before operationsChris Wilson1-5/+6
Commit fabef825626d ("drm/i915: Drop struct_mutex around frontbuffer flushes") adds a dependency to ifbdev->vma when flushing the framebufer, but the checks are only against the existence of the ifbdev->fb and not against ifbdev->vma. This leaves a window of opportunity where we may try to operate on the fbdev prior to it being probed (thanks to asynchronous booting).

2017-07-07drm/i915/cnl: Get DDI clock based on PLLs.Rodrigo Vivi2-0/+113
PLLs are the source clocks for the DDIs so in order to determine the ddi clock we need to check the PLL configuration. v2: Mika pointed out that 24 was hardcoded while it should consider ref clock that can be either 24KHz or 19.2KHz on CNL.
