Thu, 24 Oct 2024 17:54:42 +0000

drm: handle HAS_IOPORT dependenciesIn a future patch HAS_IOPORT=n will disable inb()/outb() and friends atcompile time. We thus need to add HAS_IOPORT as dependency for thosedrivers using them. In the bochs driver there is optional MMIO supportdetected at runtime, warn if this isn't taken when HAS_IOPORT is notdefined.There is also a direct and hard coded use in cirrus.c which according tothe comment is only necessary during resume.

This functions calls hmm_range_fault to readCPU page tables and populate all pfns/pages of this virtual addressrange. For system memory page, dma-mapping is performedto get a dma-address which can be used later for GPU to access pages.v1: Address review comments: separate a npage_in_range function (Matt) reparameterize function xe_userptr_populate_range function (Matt) move mmu_interval_read_begin() call into while loop (Thomas) s/mark_range_accessed/xe_mark_range_accessed (Thomas) use set_page_dirty_lock (vs set_page_dirty) (Thomas) move a few checking in xe_vma_userptr_pin_pages to hmm.c (Matt)v2: Remove device private page support. Only support system pages for now. use dma-map-sg rather than dma-map-page (Matt/Thomas)v3: Address review comments: Squash patch "drm/xe: Introduce a helper to free sg table" to current patch (Matt) start and end addresses are already page aligned (Matt) Do mmap_read_lock and mmap_read_unlock for hmm_range_fault incase of non system allocator call.

(Matt) Free sgtable incase of dma_map_sgtable failure.(Matt) Modify loop for hmm_range_fault.(Matt)v4: Remove the dummy function for xe_hmm_userptr_populate_range since CONFIG_HMM_MIRROR is needed.
