2022-02-02drm/i915: Only include i915_reg.h from .c filesMatt Roper1-1/+0
Several of our i915 header files, have been including i915_reg.h. This means that any change to i915_reg.h will trigger a full rebuild of pretty much every file of the driver, even those that don't have any kind of register access. Let's delete the i915_reg.h include from all headers and add an explicit include from the .c files that truly need the register definitions; those that need a definition of i915_reg_t for a function definition can get it from i915_reg_defs.h instead. We also remove two non-register #define's (VLV_DISPLAY_BASE and GEN12_SFC_DONE_MAX) into i915_reg_defs.h to allow us to drop the i915_reg.h include from a couple of headers. There's probably a lot more header dependency optimization possible, but the changes here roughly cut the number of files compiled after 'touch i915_reg.h' in half --- a good first step.

2022-02-02drm/i915: Introduce G12 subplatform of DG2Matt Roper1-8/+11
Another fork of the DG2 design has appeared, known as "DG2-G12;" let's add it as a new subplatform. As with G11, the GT stepping resets back to A0 (so a DG2-G12 A0 is similar, but not identical, to a DG2-G10 C0) but the display steppings continue to use the same numbering scheme as G10 and G11. Some existing DG2 workarounds are starting to be extended to the DG2-G12 subplatform. So far only workarounds that were "permanent" for both DG2-G10 and DG2-G11 have been tagged for DG2-G12, but more stepping-specific workarounds are likely to show up in the future.

2022-01-26drm/i915/wopcm: Handle pre-programmed WOPCM registersDaniele Ceraolo Spurio1-0/+3
Starting from DG2, some of the programming previously done by i915 and the GuC has been moved to the GSC and the relevant registers are no longer writable by either CPU or GuC. This is also referred to as GuC deprivilege. On the i915 side, this affects the WOPCM registers: these are no longer programmed by the driver and we do instead expect to find them already set. This can lead to verification failures because in i915 we cheat a bit with the WOPCM size defines, to keep the code common across platforms, by sometimes using a smaller WOPCM size that the actual HW support (which isn't a problem because the extra size is not needed if the FW fits in the smaller chunk), while the pre-programmed values can use the actual size. Given tha the new programming entity is trusted, relax the amount of the checks done on the pre-programmed values by not limiting the max programmed size. In the extremely unlikely scenario that the registers have been misprogrammed, we will still fail later at DMA time. v2: drop special case for DG2 G10 A0 (Alan) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Stuart Summers <stuart.summers@intel.com> Cc: John Harrison <john.c.harrison@intel.com> Cc: Alan Previn <alan.previn.teres.alexis@intel.com> Reviewed-by: Alan Previn <alan.previn.teres.alexis@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220120212947.3440448-1-daniele.ceraolospurio@intel.com

i915_gem_evict_something, v2. Because we will start to require the obj->resv lock for unbinding, ensure these vma eviction utility functions also take the lock. This requires some function signature changes, to ensure that the ww context is passed around, but is mostly straightforward.

This allows us to evict the entire vm even if we already hold some objects' locks. Previously, this was spread over several commits, but it makes more sense to commit the changes to i915_gem_evict_vm separately from the changes to i915_gem_evict_something() and i915_gem_evict_for_node().

2022-01-11drm/i915: Use vma resources for async unbindingThomas Hellström1-0/+1
Implement async (non-blocking) unbinding by not syncing the vma before calling unbind on the vma_resource. Add the resulting unbind fence to the object's dma_resv from where it is picked up by the ttm migration code. Ideally these unbind fences should be coalesced with the migration blit fence to avoid stalling the migration blit waiting for unbind, as they can certainly go on in parallel, but since we don't yet have a reasonable data structure to use to coalesce fences and attach the resulting fence to a timeline, we defer that for now. Note that with async unbinding, even while the unbind waits for the preceding bind to complete before unbinding, the vma itself might have been destroyed in the process, clearing the vma pages. Therefore we can only allow async unbinding if we have a refcounted sg-list and keep a refcount on that for the vma resource pages to stay intact until binding occurs. If this condition is not met, a request for an async unbind is diverted to a sync unbind. v2: - Use a separate kmem_cache for vma resources for now to isolate their memory allocation and aid debugging. - Move the check for vm closed to the actual unbinding thread. Regardless of whether the vm is closed, we need the unbind fence to properly wait for capture. - Clear vma_res::vm on unbind and update its documentation. v4: - Take cache coloring into account when searching for vma resources pending unbind. (Matthew Auld) v5: - Fix timeout and error check in i915_vma_resource_bind_dep_await(). - Avoid taking a reference on the object for async binding if async unbind capable. - Fix braces around a single-line if statement. v6: - Fix up the cache coloring adjustment. (Kernel test robot <lkp@intel.com>) - Don't allow async unbinding if the vma_res pages are not the same as the object pages.

2021-12-23drm/i915: Use trylock instead of blocking lock for __i915_gem_free_objects.Maarten Lankhorst1-2/+2
Convert free_work into delayed_work, similar to ttm to allow converting the blocking lock in __i915_gem_free_objects to a trylock. Unlike ttm, the object should already be idle, as it's kept alive by a reference through struct i915_vma->active, which is dropped after all vma's are idle. Because of this, we can use a no wait by default, or when the lock is contested, we use ttm's 10 ms. The trylock should only fail when the object is sharing it's resv with other objects, and typically objects are not kept locked for a long time, so we can safely retry on failure.

Collect the dipslay related mask under the display sub-structure in intel_device_info. Note that there is a slight change in behaviour in that we zero out .display entirely when !HAS_DISPLAY (aka. pipe_mask==0), so now we also zero out the other masks (although cpu_transocder_mask should already be zero of pipe_mask is zero). abox_mask is only used by the display core init when HAS_DISPLAY is true, so the actual behaviour of the system shouldn't change despite the zeroing of these masks. There is a lot more display stuff directly in device info that could be moved over. Maybe someone else will be inspired to do it...
