2021-10-02drm/i915: fix blank screen booting crashesHugh Dickins1-2/+3
5.15-rc1 crashes with blank screen when booting up on two ThinkPads using i915. Bisections converge convincingly, but arrive at different and suprising "culprits", none of them the actual culprit. netconsole (with init_netconsole() hacked to call i915_init() when logging has started, instead of by module_init()) tells the story: kernel BUG at drivers/gpu/drm/i915/i915_sw_fence.c:245! with RSI: ffffffff814d408b pointing to sw_fence_dummy_notify(). I've been building with CONFIG_CC_OPTIMIZE_FOR_SIZE=y, and that function needs to be 4-byte aligned.

2021-09-28drm/amdgpu: check tiling flags when creating FB on GFX8-Simon Ser1-0/+31
On GFX9+, format modifiers are always enabled and ensure the frame-buffers can be scanned out at ADDFB2 time. On GFX8-, format modifiers are not supported and no other check is performed. This means ADDFB2 IOCTLs will succeed even if the tiling isn't supported for scan-out, and will result in garbage displayed on screen [1]. Fix this by adding a check for tiling flags for GFX8 and older. The check is taken from radeonsi in Mesa (see how is_displayable is populated in gfx6_compute_surface).

In commit 4e5c8a99e1cb ("drm/i915: Drop i915_request.lock requirement for intel_rps_boost()"), we decoupled the rps worker from the pm so that we could avoid the synchronization penalty which makes the assertion liable to run too early.

2021-09-27drm/i915/request: fix early tracepointsMatthew Auld1-9/+2
Currently we blow up in trace_dma_fence_init, when calling into get_driver_name or get_timeline_name, since both the engine and context might be NULL(or contain some garbage address) in the case of newly allocated slab objects via the request ctor. Note that we also use SLAB_TYPESAFE_BY_RCU here, which allows requests to be immediately freed, but delay freeing the underlying page by an RCU grace period. With this scheme requests can be re-allocated, at the same time as they are also being read by some lockless RCU lookup mechanism. In the ctor case, which is only called for new slab objects(i.e allocate new page and call the ctor for each object) it's safe to reset the context/engine prior to calling into dma_fence_init, since we can be certain that no one is doing an RCU lookup which might depend on peeking at the engine/context, like in active_engine(), since the object can't yet be externally visible. In the recycled case(which might also be externally visible) the request refcount always transitions from 0->1 after we set the context/engine etc, which should ensure it's valid to dereference the engine for example, when doing an RCU list-walk, so long as we can also increment the refcount first. If the refcount is already zero, then the request is considered complete/released. If it's non-zero, then the request might be in the process of being re-allocated, or potentially still in flight, however after successfully incrementing the refcount, it's possible to carefully inspect the request state, to determine if the request is still what we were looking for. Note that all externally visible requests returned to the cache must have zero refcount. One possible fix then is to move dma_fence_init out from the request ctor. Originally this was how it was done, but it was moved in: commit 855e39e65cfc33a73724f1cc644ffc5754864a20 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon Feb 3 09:41:48 2020 +0000 drm/i915: Initialise basic fence before acquiring seqno where it looks like intel_timeline_get_seqno() relied on some of the rq->fence state, but that is no longer the case since: commit 12ca695d2c1ed26b2dcbb528b42813bd0f216cfc Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Tue Mar 23 16:49:50 2021 +0100 drm/i915: Do not share hwsp across contexts any more, v8. intel_timeline_get_seqno() could also be cleaned up slightly by dropping the request argument. Moving dma_fence_init back out of the ctor, should ensure we have enough of the request initialised in case of trace_dma_fence_init. Functionally this should be the same, and is effectively what we were already open coding before, except now we also assign the fence->lock and fence->ops, but since these are invariant for recycled requests(which might be externally visible), and will therefore already hold the same value, it shouldn't matter. An alternative fix, since we don't yet have a fully initialised request when in the ctor, is just setting the context/engine as NULL, but this does require adding some extra handling in get_driver_name etc. v2(Daniel): - Try to make the commit message less confusing Fixes: 855e39e65cfc ("drm/i915: Initialise basic fence before acquiring seqno") Signed-off-by: Matthew Auld <matthew.auld@intel.com> Cc: Michael Mason <michael.w.mason@intel.com> Cc: Daniel Vetter <daniel@ffwll.ch> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20210921134202.3803151-1-matthew.auld@intel.com (cherry picked from commit be988eaee1cb208c4445db46bc3ceaf75f586f0b) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2021-09-23drm/amd/pm: Update intermediate power state for SILijo Lazar1-0/+2
Update the current state as boot state during dpm initialization. During the subsequent initialization, set_power_state gets called to transition to the final power state. set_power_state refers to values from the current state and without current state populated, it could result in NULL pointer dereference. For ex: on platforms where PCI speed change is supported through ACPI ATCS method, the link speed of current state needs to be queried before deciding on changing to final power state's link speed. The logic to query ATCS-support was broken on certain platforms. The issue became visible when broken ATCS-support logic got fixed with commit f9b7f3703ff9 ("drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)").

2021-09-21drm/i915: Move __i915_gem_free_object to ttm_bo_destroyMaarten Lankhorst1-4/+5
When we implement delayed destroy, we may have a second call to the delete_mem_notify() handler, while free_object() only should be called once. Move it to bo->destroy(), to ensure it's only called once. This fixes some weird memory corruption issues with delayed destroy when async eviction is used.

Otherwise(on sound driver missing), BACO cannot be kicked in correctly and hang will be observed on RUNPM exit.
