From: "Thomas Hellström" <thomas.hellstrom@linux.intel.com> To: intel-gfx@lists.freedesktop.org, dri-devel@lists.freedesktop.org Cc: "Thomas Hellström" <thomas.hellstrom@linux.intel.com>, "Christian König" <christian.koenig@amd.com> Subject: [PATCH v10 00/11] Move LMEM (VRAM) management over to TTM Date: Wed, 2 Jun 2021 10:38:07 +0200 [thread overview] Message-ID: <20210602083818.241793-1-thomas.hellstrom@linux.intel.com> (raw) This is an initial patch series to move discrete memory management over to TTM. It will be followed up shortly with adding more functionality. The buddy allocator is temporarily removed along with its selftests and It is replaced with the TTM range manager and some selftests are adjusted to account for introduced fragmentation. Work is ongoing to reintroduce the buddy allocator as a TTM resource manager. A new memcpy ttm move is introduced that uses kmap_local() functionality rather than vmap(). Among other things stated in the patch commit message it helps us deal with page-pased LMEM memory. It is generic enough to replace the ttm memcpy move with some additional work if so desired. On x86 it also enables prefetching reads from write-combined memory. Finally the old i915 gem object LMEM backend is replaced with a i915 gem object TTM backend and some additional i915 gem object ops are introduced to support the added functionality. Currently it is used only to support management and eviction of the LMEM region, but work is underway to extend the support to system memory. In this way we use TTM the way it was originally intended, having the GPU binding taken care of by driver code. Intention is to follow up with - System memory support - Pipelined accelerated moves / migration - Re-added buddy allocator in the TTM framework v2: - Add patches to move pagefaulting over to TTM - Break out TTM changes to separate patches - Address various review comments as detailed in the affected patches v3: - Drop TTM pagefaulting patches for now due changing approach due to a NAK. - Address feedback on TTM patches - Move the new TTM memcpy functionality into TTM. - Move fast WC memcpy to drm - Various fixes all over the place as shown in patch commit messages. v4: - Re-add TTM pagefaulting patches. - Addressed review feedback mainly from Matthew Auld - Fixed the mock ttm device code that was using an incorrect approach. v5: - Cleanups in the TTM pagefaulting patches. - Just add the WC memcpy to DRM without removing from i915 (Suggested by Daniel Vetter). - Various minor fixes as reported in patch log messages. v6: - Fix a merge conflict causing build error. v7: - Fix the WC memcpy compilation and perform a fallback memcpy in addition to warning in interrupt (Suggested by Christian König) - Renistate check for ttm_tt_is_populated() on swapout. v8: - Added a couple of acks and r-bs - pgoff_t -> u32 in interface of ttm_move_memcpy. - Fix missing export in !X86 WC memcpy. v9: - Fix a NULL pointer deref if bo->ttm == NULL v10: - Fix a kerneldoc title underline Cc: Christian König <christian.koenig@amd.com> Maarten Lankhorst (2): drm/vma: Add a driver_private member to vma_node. drm/i915: Use ttm mmap handling for ttm bo's.
