| * drm/amdgpu: revert tile table update for olandJean Delvare2017-09-141-1/+188
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several users have complained that the tile table update broke Oland support. Despite several attempts to fix it, the root cause is still unknown at this point and no solution is available. As it is not acceptable to leave a known regression breaking a major functionality in the kernel for several releases, let's just reverse this optimization for now. It can be implemented again later if and only if the breakage is understood and fixed. As there were no complaints for Hainan so far, only the Oland part of the offending commit is reverted. Optimization is preserved on Hainan, so this commit isn't an actual revert of the original.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 10e709cb296c98424c03408d23e3addeddcd4088. The patch doesn't work at all: 1. The CS can still be blocked because of amdgpu_ctx_add_fence(). 2. The order of submission isn't correct any more. 3. We could end up using freed up memory because we now drop the ctx reference to early. This needs to be fixed cleanly by doing the context handling after the BO handling, but this is a larger task just avoid the obvious crashes for now.

While most users will make use of this feature, those with special functions (in addition to the generic insert, delete, search calls) will avoid using the cached option as they can do funky things with insertions -- for example, vma_interval_tree_insert_after().

AMD has started cleaning the pipe and sending patches from their internal development to the upstream community. The plan as I understand it is to first get all the non-dGPU patches to upstream and then move to upstream dGPU support. The patches here are relevant only for Kaveri and Carrizo. The following is a summary of the changes: - Add new IOCTL to set a Scratch memory VA - Update PM4 headers for new firmware that support scratch memory - Support image tiling mode - Remove all uses of BUG_ON - Various Bug fixes and coding style fixes * tag 'drm-amdkfd-next-2017-08-18' of git://people.freedesktop.org/~gabbayo/linux: (24 commits) drm/amdkfd: Implement image tiling mode support v2 drm/amdgpu: Add kgd kfd interface get_tile_config() v2 drm/amdkfd: Adding new IOCTL for scratch memory v2 drm/amdgpu: Add kgd/kfd interface to support scratch memory v2 drm/amdgpu: Program SH_STATIC_MEM_CONFIG globally, not per-VMID drm/amd: Update MEC HQD loading code for KFD drm/amdgpu: Disable GFX PG on CZ drm/amdkfd: Update PM4 packet headers drm/amdkfd: Clamp EOP queue size correctly on Gfx8 drm/amdkfd: Add more error printing to help bringup v2 drm/amdkfd: Handle remaining BUG_ONs more gracefully v2 drm/amdkfd: Allocate gtt_sa_bitmap in long units drm/amdkfd: Fix doorbell initialization and finalization drm/amdkfd: Remove BUG_ONs for NULL pointer arguments drm/amdkfd: Remove usage of alloc(sizeof(struct... drm/amdkfd: Fix goto usage v2 drm/amdkfd: Change x==NULL/false references to !x drm/amdkfd: Consolidate and clean up log commands drm/amdkfd: Clean up KFD style errors and warnings v2 drm/amdgpu: Remove hard-coded assumptions about compute pipes ...

This is a non-backwards compatible change and it's about two years old. So no point keeping the old version around conditionally.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gfx8 HW incorrectly clamps CP_HQD_EOP_CONTROL.EOP_SIZE, which can lead to scheduling deadlock due to SE EOP done counter overflow. Enforce a EOP queue size limit which prevents the CP from sending more than 0xFF events at a time.
