The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:

Whenever KMD maps region larger than 64kB that is both aligned and contiguous, set contiguous bit (52) in MMU PTE descriptor for each page in that region. This allows to treat 16 contiguous pages as one and reduce number of MMU page walks required which results in lower latency. Signed-off-by:

Simplify and unify naming convention in MMU600 page tables configuration. All DMA addresses in page tables directly accessed by VPU are called with _dma sufix and all CPU pointers to those page tables have _ptr sufix. Base pointers used to do a page walk on the CPU have corresponding names: pud_ptrs (pointers used to get access to PUD DMA) pmd_ptrs (pointers used to get access to PMD DMA) pte_ptrs (pointers used to get access to PTE DMA) with the following convention: u64 *pud_dma_ptr = pud_ptrs[pgd_idx]; *pud_dma_ptr = pud_dma; u64 *pmd_dma_ptr = pmd_ptrs[pgd_idx][pud_idx]; *pmd_dma_ptr = pmd_dma; u64 *pte_dma_ptr = pte_ptrs[pgd_idx][pud_idx][pmd_idx]; *pte_dma_ptr = pte_dma; On the way change to coherent dma allocation, _wc is only valid on ARM and was used by mistake.

Use dma-fence-unwrap API for waiting each dma-fence of the in-fence array individually. Sync file's in-fence array always has a non-matching fence context ID, which doesn't allow to skip waiting of fences with a matching context ID in a case of a merged sync file fence. Suggested-by:

Move virtio_gpu_execbuffer_ioctl() into separate virtgpu_submit.c file, refactoring and optimizing the code along the way to ease addition of new features to the ioctl. The optimization is done by using optimal ordering of the job's submission steps, reducing code path from the start of the ioctl to the point of pushing job to virtio queue. Job's initialization is now performed before in-fence is awaited and out-fence setup is made after sending out job to virtio. Reviewed-by:

The Amlogic G12A/G12B/SM1 SoCs embeds a Synopsys DW-MIPI-DSI transceiver (ver 1.21a), with a custom glue managing the IP resets, clock and data inputs similar to the DW-HDMI Glue on other Amlogic SoCs. This adds support for the Glue managing the transceiver, mimicing the init flow provided by Amlogic to setup the ENCL encoder, the glue, the transceiver, the digital D-PHY and the Analog PHY in the proper way. An optional "MEAS" clock can be enabled to measure the delay between each vsync feeding the DW-MIPI-DSI transceiver. Signed-off-by:

Only DW-HDMI currently needs components since it reuses the drm-meson driver context to access HHI registers (sic). Once this is solved, we can get rid on components. Until now, limit the components matching to the dw-hdmi compatibles we know to require this hack, for other bridges simply use probe defer instead and get over this components sitation. The back story is that we simply cannot attach DSI adapters bridges if we use components, only DSI panels, this is because we bind/unbind the DSI controller at each drm-meson driver master bind tentative. With this the I2C DSI bridge is unable to find the DSI controller host and everything fails to probe. This will simplify a lot adding new or older HDMI bridges.

If the case the HDMI controller fails to bind, we try to unbind all components before calling drm_dev_put() which makes drm_bridge_detach() crash because unbinding the HDMI controller frees the bridge memory. The solution is the unbind all components at the end like in the remove path. Reviewed-by:

Use the regular fbdev helpers for framebuffer I/O instead of DRM's helpers. Msm does not use damage handling, so DRM's fbdev helpers are mere wrappers around the fbdev code. By using fbdev helpers directly within each DRM fbdev emulation, we can eventually remove DRM's wrapper functions entirely. Msm's fbdev emulation has been incomplete as it didn't implement damage handling. Partilly fix this by implementing damage handling for write and draw operation. It is still missing for mmaped pages. v4: * use initializer macros for struct fb_ops * partially support damage handling v2: * use FB_SYS_HELPERS option Signed-off-by:
