Since we want to revoke the ggtt vma from only under the ggtt->mutex, we need to move protection of the userfault tracking from the struct_mutex to the ggtt->mutex. Signed-off-by:

We can reduce the locking for fence registers from the dev->struct_mutex to a local mutex. We could introduce a mutex for the sole purpose of tracking the fence acquisition, except there is a little bit of overlap with the fault tracking, so use the i915_ggtt.mutex as it covers both. Signed-off-by:

Most importantly per-process address spaces on GPUs that are capable of providing proper isolation has finished baking. This is the base for our softpin implementation, which allows us to support the texture descriptor buffers used by GC7000 series GPUs without a major UAPI extension/rework.

We're not allowed to create new properties after device registration so for MST connectors we need to either create the max_bpc property earlier, or we reuse one we already have. Let's do the latter apporach since the corresponding SST connector already has the prop and its min/max are correct also for the MST connector. The problem was highlighted by commit 4f5368b5 ("drm/kms: Catch mode_object lifetime errors") which results in the following spew: [ 1330.878941] WARNING: CPU: 2 PID: 1554 at drivers/gpu/drm/drm_mode_object.c:45 __drm_mode_object_add+0xa0/0xb0 [drm] ...

When under severe stress for GTT mappable space, the LRU eviction model falls off a cliff. We spend all our time scanning the much larger non-mappable area searching for something within the mappable zone we can evict. Turn this on its head by only using the full vma for the object if it is already pinned in the mappable zone or there is sufficient *free* space to accommodate it (prioritizing speedy reuse). If there is not, immediately fall back to using small chunks (tilerow for GTT mmap, single pages for pwrite/relocation) and using random eviction before doing a full search.

The current SKUs added for Tiger Lake don't have DDIC hooked up, even though it is supported by the SoC. The current state for these SKUs is problematic since while enabling the combo phy, PORT_COMP_DW* return 0xFFFFFFFF, which is invalid per register definition. During initialization we check what phys are not yet enabled by reading PHY_MISC_C and try to enable it by toggling the "DE to IO Comp Pwr Down" bit. But after that any read to the PORT_COMP_DW* returns invalid results.

The current assertion tries to make sure that we do not over count the number of used PDE inside a page directory -- that is with an array of 512 pde, we do not expect more than 512 elements used! However, our assertion has to take into account that as we pin an element into the page directory, the caller first pins the page directory so the usage count is one higher. However, this should be one extra pin per thread, and the upper bound is that we may have one thread for each entry. Signed-off-by:

The CSB format has been reworked for Gen12 to include information on both the context we're switching away from and the context we're switching to. After the change, some of the events don't have their own bit anymore and need to be inferred from other values in the csb. One of the context IDs (0x7FF) has also been reserved to indicate the invalid ctx, i.e. engine idle.
