2020-11-11drm/ttm: add multihop infrastrucutre (v3)Dave Airlie
Currently drivers get called to move a buffer, but if they have to move it temporarily through another space (SYSTEM->VRAM via TT) then they can end up with a lot of ttm->driver->ttm call stacks, if the temprorary space moves requires eviction. Instead of letting the driver do all the placement/space for the temporary, allow it to report back (-EMULTIHOP) and a placement (hop) to the move code, which will then do the temporary move, and the correct placement move afterwards. This removes a lot of code from drivers, at the expense of adding some midlayering. I've some further ideas on how to turn it inside out, but I think this is a good solution to the call stack problems. v2: separate out the driver patches, add WARN for getting MULTHOP in paths we shouldn't (Daniel) v3: use memset (Christian) Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: hristian König <christian.koenig@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201109005432.861936-2-airlied@gmail.com

2020-11-10drm: remove pgprot_decrypted() before calls to io_remap_pfn_range()Jason Gunthorpe
commit f8f6ae5d077a ("mm: always have io_remap_pfn_range() set pgprot_decrypted()") moves the pgprot_decrypted() into io_remap_pfn_range(). Delete any, now confusing, open coded calls that directly precede io_remap_pfn_range(): - drm_io_prot() is only in drm_mmap_locked() to call io_remap_pfn_range() - fb_mmap() immediately calls vm_iomap_memory() which is a convenience wrapper for io_remap_pfn_range() Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/0-v1-2e6a0db57868+166-drm_sme_clean_jgg@nvidia.com
2020-11-10drm: DRM_KMB_DISPLAY should depend on ARCH_KEEMBAYGeert Uytterhoeven
The Intel Keem Bay display controller is only present on Intel Keem Bay SoCs. Hence add a dependency on ARCH_KEEMBAY, to prevent asking the user about this driver when configuring a kernel without Intel Keem Bay platform support. Note that: 1. The dependency on ARM is dropped, as Keem Bay SoCs are only supported in arm64 kernel builds, 2. The dependencies on OF and COMMON_CLK can be dropped for compile-testing, as the driver builds fine regardless.

2020-11-10drm/omap: Fix runtime PM imbalance on errorDinghao Liu
pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code. However, users of its direct wrappers in omapdrm assume that PM usage counter will not change on error. Thus a pairing decrement is needed on the error handling path for these wrappers to keep the counter balanced.

2020-11-10drm: Use state helper instead of CRTC state pointerMaxime Ripard

Program display related vregs to proper value at initialization, setup virtual monitor and hotplug. vGPU virtual display vregs inherit the value from pregs. The virtual DP monitor is always setup on PORT_B for BXT/APL. However the host may connect monitor on other PORT or without any monitor connected. Without properly setup PIPE/DDI/PLL related vregs, guest driver may not setup the virutal display as expected, and the guest desktop may not be created. Since only one virtual display is supported, enable PIPE_A only. And enable transcoder/DDI/PLL based on which port is setup for BXT/APL. V2: Revise commit message.

2020-11-09drm/i915/region: fix order when adding blocksMatthew Auld
When performing an allocation we try split it down into the largest possible power-of-two blocks/pages-sizes, and for the common case we expect to allocate the blocks in descending order. This also naturally fits with our GTT alignment tricks(including the hugepages selftest), where we sometimes try to align to the largest possible GTT page-size for the allocation, in the hope that translates to bigger GTT page-sizes. Currently, we seem to incorrectly add the blocks in the opposite order, which is definitely not the intended behaviour.

2020-11-09drm/cma-helper: Make default object functions the defaultThomas Zimmermann
As GEM object functions are now mandatory, DRM drivers based on CMA helpers either set them in their implementation of gem_create_object, or use the default via drm_gem_cma_create_object_default_funcs(). Simplify this by setting the default CMA object functions for all objects that don't have any functions of their own. Follows the pattern of similar code in SHMEM and VRAM helpers.

2020-11-09drm/fb_helper: Support framebuffers in I/O memoryThomas Zimmermann
At least sparc64 requires I/O-specific access to framebuffers. This patch updates the fbdev console accordingly. For drivers with direct access to the framebuffer memory, the callback functions in struct fb_ops test for the type of memory and call the rsp fb_sys_ of fb_cfb_ functions. Read and write operations are implemented internally by DRM's fbdev helper. For drivers that employ a shadow buffer, fbdev's blit function retrieves the framebuffer address as struct dma_buf_map, and uses dma_buf_map interfaces to access the buffer. The bochs driver on sparc64 uses a workaround to flag the framebuffer as I/O memory and avoid a HW exception. With the introduction of struct dma_buf_map, this is not required any longer. The patch removes the rsp code from both, bochs and fbdev. v7: * use min_t(size_t,) (kernel test robot) * return the number of bytes read/written, if any (fbdev testcase) v5: * implement fb_read/fb_write internally (Daniel, Sam) v4: * move dma_buf_map changes into separate patch (Daniel) * TODO list: comment on fbdev updates (Daniel) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Tested-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20201103093015.1063-11-tzimmermann@suse.de
