drm_gem_map_dma_buf() requires drm_gem_object_funcs.get_sg_table to be implemented, or else WARNs. Allow drivers to leave this hook unimplemented to implement purely local DMA-BUFs (ie, DMA-BUFs which cannot be imported anywhere else but the device which allocated them). In that case, reject imports to other devices in drm_gem_map_attach(). v2: new patch v3: use ENOSYS Signed-off-by:

lima maintains a context manager per drm_file, similar to amdgpu. In order to account for the complete usage per drm_file, all of the associated contexts need to be considered. Previously released contexts also need to be accounted for but their drm_sched_entity info is gone once they get released, so account for it in the ctx_mgr. Signed-off-by:

Some SoCs implementing ARM Mali GPUs are subject to speed binning: this means that some versions of the same SoC model may need to be limited to a slower frequency compared to the other: this is being addressed by reading nvmem (usually, an eFuse array) containing a number that identifies the speed binning of the chip, which is usually related to silicon quality. To address such situation, add basic support for reading the speed-bin through nvmem, as to make it possible to specify the supported hardware in the OPP table for GPUs. This commit also keeps compatibility with any platform that does not specify (and does not even support) speed-binning. Signed-off-by:

This series adds a deadline hint to fences, so realtime deadlines such as vblank can be communicated to the fence signaller for power/ frequency management decisions. This is partially inspired by a trick i915 does, but implemented via dma-fence for a couple of reasons: 1) To continue to be able to use the atomic helpers 2) To support cases where display and gpu are different drivers See https://patchwork.freedesktop.org/series/93035/ This does not yet add any UAPI, although this will be needed in a number of cases: 1) Workloads "ping-ponging" between CPU and GPU, where we don't want the GPU freq governor to interpret time stalled waiting for GPU as "idle" time 2) Cases where the compositor is waiting for fences to be signaled before issuing the atomic ioctl, for example to maintain 60fps cursor updates even when the GPU is not able to maintain that framerate.

As the finished fence is the one that is exposed to userspace, and therefore the one that other operations, like atomic update, would block on, we need to propagate the deadline from from the finished fence to the actual hw fence. v2: Split into drm_sched_fence_set_parent() (ckoenig) v3: Ensure a thread calling drm_sched_fence_set_deadline_finished() sees fence->parent set before drm_sched_fence_set_parent() does this test_bit(DMA_FENCE_FLAG_HAS_DEADLINE_BIT).

Merge tag 'exynos-drm-next-for-v6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next A patch series for moving MIPI-DSI driver for Exynos DRM to drm/bridge directory so that I.MX SoC family can also share the same device driver. Samsung MIPI DSIM device is a common IP that can be used by Exynos and I.MX8M Mini/Nano/Plus SoC. Regarding this, this patch series has added several things below to existing MIPI DSI driver, - Add exynos_dsi_type enum type to provide controller data from different platforms. - Add two pipeline detection ways support - existing Exynos DSI child node and I.MX family of-graph port or ports. - Consider component and bridged based DRM drivers. - Add device tree binding support of I.MX family.

Add extras to support i.MX8M Plus. The main change is the removal of HS/VS/DE signal inversion in the LCDIFv3-DSIM glue logic, otherwise the implementation of this IP in i.MX8M Plus is very much compatible with the i.MX8M Mini/Nano one. Reviewed-by:

Samsung MIPI DSIM controller is common DSI IP that can be used in various SoCs like Exynos, i.MX8M Mini/Nano. In order to access this DSI controller between various platform SoCs, the ideal way to incorporate this in the drm stack is via the drm bridge driver. We already have a consolidated code for supporting component and bridge based DRM drivers, so keep the exynos component based code in existing exynos_drm_dsi.c and move generic bridge code as part of samsung-dsim.c Tested-by:

IRQ handler for te-gpio seems to be common across DSIM host. However, Exynos is handling this via CRTC drivers but there is no clear evidence on how the same has been handled in i.MX8MM. Keeping the handler as-it-is can be a viable option but adding DSIM bridge core in upcoming patches is not possible to call Exynos CRTC handler as DSIM bridge has to be common across DRM bridge core instead of platform specific DRM drivers like Exynos here. So, this patch handles the handler via platform host helper, so-that handling platform specific hook across Exynos and generic can be reasonable till it makes it generic across all platforms.

DSI host registration, attach and detach operations are quite different for the component and bridge-based DRM drivers. Supporting generic bridge driver to use both component and bridge based DRM drivers can be tricky and would require additional host related operation hooks. Add host operation hooks for registering and unregistering Exynos and generic drivers, where Exynos hooks are used in existing Exynos component based DRM drivers and generic hooks are used in i.MX8M bridge based DRM drivers. Add host attach and detach operation hooks for Exynos component DRM drivers and those get invoked while DSI core host attach and detach gets called. Tested-by:
