Use an rwlock instead of spinlock for the global notifier lock to reduce risk of contention in execbuf. Protect object state with the object lock whenever possible rather than with the global notifier lock Don't take an explicit page_ref in userptr_submit_init() but rather call get_pages() after obtaining the page list so that get_pages() holds the page_ref. This means we don't need to call userptr_submit_fini(), which is needed to avoid awkward locking in our upcoming VM_BIND code. Signed-off-by:

Use the ttm handlers for servicing page faults, and vm_access. We do our own validation of read-only access, otherwise use the ttm handlers as much as possible. Because the ttm handlers expect the vma_node at vma->base, we slightly need to massage the mmap handlers to look at vma_node->driver_private to fetch the bo, if it's NULL, we assume i915's normal mmap_offset uapi is used. This is the easiest way to achieve compatibility without changing ttm's semantics. Signed-off-by:

This allows drivers to distinguish between different types of vma_node's. The readonly flag was unused and is thus removed. This is a temporary solution, until i915 is converted completely to use ttm for bo's. Signed-off-by:

Thomas Hellström authored
Most logical place to introduce TTM buffer objects is as an i915 gem object backend. We need to add some ops to account for added functionality like delayed delete and LRU list manipulation. Initially we support only LMEM and SYSTEM memory, but SYSTEM (which in this case means evicted LMEM objects) is not visible to i915 GEM yet. The plan is to move the i915 gem system region over to the TTM system memory type in upcoming patches. We set up GPU bindings directly both from LMEM and from the system region, as there is no need to use the legacy TTM_TT memory type. We reserve that for future porting of GGTT bindings to TTM. Remove the old lmem backend. Signed-off-by:

Drop disabling of gfxoff during VCN use. This allows gfxoff to kick in and potentially save power if the user is not using gfx for color space conversion or scaling. VCN1.0 had a bug which prevented it from working properly with gfxoff, so we disabled it while using VCN. That said, most apps today use gfx for scaling and color space conversion rather than overlay planes so it was generally in use anyway. This was fixed on VCN2+, but since we mostly use gfx for color space conversion and scaling and rapidly powering up/down gfx can negate the advantages of gfxoff, we left gfxoff disabled. As more applications use overlay planes for color space conversion and scaling, this starts to be a win, so go ahead and leave gfxoff enabled. Note that VCN1.0 uses vcn_v1_0_idle_work_handler() and vcn_v1_0_ring_begin_use() so they are not affected by this patch. Reviewed-by:

We currently treat same slice mask as a same DBuf state and skip updating the Dbuf slices, if we detect that. This is wrong as if we have a multi to single pipe change or vice versa, that would be treated as a same Dbuf state and thus no changes required, so we don't get Mbus updated, causing issues.

It activates paused psr state. v2: Address Jose's review comment. - Remove unneeded changes around the intel_psr_enable(). - Add intel_psr_post_exit() which processes waiting until PSR is idle and WA for SelectiveFetch. v3: Address Jose's review comment. - Rename intel_psr_post_exit() to intel_psr_wait_exit_locked(). - Move WA_1408330847 to intel_psr_disable_locked() - If the PSR is paused by an explicit intel_psr_paused() call, make the intel_psr_flush() not to activate PSR. v4: Address Jose's review comment. - In order to avoid the scenario of PSR is not active but there is a scheduled psr->work, it changes the check routine of intel_psr_pause() for PSR's enablement from "psr->active" to "psr->enable".
