2019-08-12Revert "drm/amdgpu: fix transform feedback GDS hang on gfx10 (v2)"Marek Olšák
This reverts commit 9ed2c993d723129f85101e51b2ccc36ef5400a67. SET_CONFIG_REG writes to memory if register shadowing is enabled, causing a VM fault. NGG streamout is unstable anyway, so all UMDs should use legacy streamout. I think Mesa is the only driver using NGG streamout.

2019-08-12drm/i915/uc: Use -EIO code for GuC initialization failuresMichal Wajdeczko
Since commit 6ca9a2beb54a ("drm/i915: Unwind i915_gem_init() failure") we believed that we correctly handle all errors encountered during GuC initialization, including special one that indicates request to run driver with disabled GPU submission (-EIO). Unfortunately since commit 121981fafe69 ("drm/i915/guc: Combine enable_guc_loading|submission modparams") we stopped using that error code to avoid unwanted fallback to execlist submission mode. In result any GuC initialization failure was treated as non-recoverable error leading to driver load abort, so we could not even read related GuC error log to investigate cause of the problem. For now always return -EIO on any uC hardware related failure.

Simple buddy allocator. We want to allocate properly aligned power-of-two blocks to promote usage of huge-pages for the GTT, so 64K, 2M and possibly even 1G. While we do support allocating stuff at a specific offset, it is more intended for preallocating portions of the address space, say for an initial framebuffer, for other uses drm_mm is probably a much better fit. Anyway, hopefully this can all be thrown away if we eventually move to having the core MM manage device memory.

2019-08-10drm/imx: fix opencoded use of drm_panel_*Sam Ravnborg
Use the drm_panel_get_modes() function to get the modes. This patch leave one test for the function pointer: panel->funcs->get_modes This is used to check if the panel may have any modes. There is no direct replacement. We may be able to just check that drm_panel_get_modes() return > 0, but as this is not the same functionality it is left for later.

2019-08-10drm/i915/gtt: disable 2M pages for pre-gen11Matthew Auld
We currently disable THP(Transparent-Huge-Pages) for our shmem objects due to a performance regression with read BW in some internal benchmarks. Given that this is our main source of 2M pages, there really isn't much point in enabling 2M GTT pages, especially as that comes at the cost of disabling the GTT cache. However from gen11 it looks like we should hopefully see the HW issue resolved. Given this opt for only enabling 2M GTT pages from gen11 onwards.

2019-08-10drm/i915/gtt: enable GTT cache by defaultMatthew Auld
For some platforms the GTT cache is by default not enabled, and currently where we explicitly enable it, we make it conditional on 2M GTT page support, since the BSpec states that we must disable it if we enable 2M/1G pages. To make this more consistent opt for blanket enabling the GTT cache for all relevant gens in a single place, while still keeping the same behaviour of checking for 2M support.

2019-08-09drm/i915: split out uncore_mmio_debugDaniele Ceraolo Spurio
Multiple uncore structures will share the debug infrastructure, so move it to a common place and add extra locking around it. Also, since we now have a separate object, it is cleaner to have dedicated functions working on the object to stop and restart the mmio debug. Apart from the cosmetic changes, this patch introduces 2 functional updates: - All calls to check_for_unclaimed_mmio will now return false when the debug is suspended, not just the ones that are active only when i915_modparams.mmio_debug is set. If we don't trust the result of the check while a user is doing mmio access then we shouldn't attempt the check anywhere. - i915_modparams.mmio_debug is not save/restored anymore around user access. The value is now never touched by the kernel while debug is disabled so no need for save/restore. v2: squash mmio_debug patches, restrict mmio_debug lock usage (Chris) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20190809063116.7527-1-chris@chris-wilson.co.uk
