2022-02-24drm/tegra: Use dev_err_probe()Dmitry Osipenko
Replace dev_printk() with a generic dev_err_probe() helper which silences noisy error messages about deferred probe and makes easy to debug failing deferred probe by printing notification about the failure to KMSG in the end of kernel booting process and by adding failing device and the reason of deferred probe to devices_deferred of debugfs. This was proven to be useful in the case of eDP driver regression by immediately showing why display driver was failing when user asked for help, otherwise it would've been much more difficult to debug such problems on a third party device that doesn't have developer setup.

2022-02-07dma-buf-map: Rename to iosys-mapLucas De Marchi
Rename struct dma_buf_map to struct iosys_map and corresponding APIs. Over time dma-buf-map grew up to more functionality than the one used by dma-buf: in fact it's just a shim layer to abstract system memory, that can be accessed via regular load and store, from IO memory that needs to be acessed via arch helpers. The idea is to extend this API so it can fulfill other needs, internal to a single driver. Example: in the i915 driver it's desired to share the implementation for integrated graphics, which uses mostly system memory, with discrete graphics, which may need to access IO memory. The conversion was mostly done with the following semantic patch: @r1@ @@ - struct dma_buf_map + struct iosys_map @r2@ @@ ( - DMA_BUF_MAP_INIT_VADDR + IOSYS_MAP_INIT_VADDR | - dma_buf_map_set_vaddr + iosys_map_set_vaddr | - dma_buf_map_set_vaddr_iomem + iosys_map_set_vaddr_iomem | - dma_buf_map_is_equal + iosys_map_is_equal | - dma_buf_map_is_null + iosys_map_is_null | - dma_buf_map_is_set + iosys_map_is_set | - dma_buf_map_clear + iosys_map_clear | - dma_buf_map_memcpy_to + iosys_map_memcpy_to | - dma_buf_map_incr + iosys_map_incr ) @@ @@ - #include <linux/dma-buf-map.h> + #include <linux/iosys-map.h> Then some files had their includes adjusted and some comments were update to remove mentions to dma-buf-map.

2021-12-16drm/tegra: Add back arm_iommu_detach_device()Dmitry Osipenko
DMA buffers of 2D/3D engines aren't mapped properly when CONFIG_ARM_DMA_USE_IOMMU=y. The memory management code of Tegra DRM driver has a longstanding overhaul overdue and it's not obvious where the problem is in this case. Hence let's add back the old workaround which we already had sometime before. It explicitly detaches DRM devices from the offending implicit IOMMU domain. This fixes a completely broken 2d/3d drivers in case of ARM32 multiplatform kernel config.

2021-12-16drm/tegra: Mark nvdec_writel() as inlineArnd Bergmann
Without CONFIG_IOMMU_API, the nvdec_writel() function is unused, causing a warning: drivers/gpu/drm/tegra/nvdec.c:48:13: error: 'nvdec_writel' defined but not used [-Werror=unused-function] 48 | static void nvdec_writel(struct nvdec *nvdec, u32 value, unsigned int offset) | ^~~~~~~~~~~~ As this is a trivial wrapper around an inline function, mark it as inline itself, which avoids the warning as well.

2021-12-16drm/tegra: dc: rgb: Allow changing PLLD rate on Tegra30+Dmitry Osipenko
Asus Transformer TF700T is a Tegra30 tablet device which uses RGB->DSI bridge that requires a precise clock rate in order to operate properly. Tegra30 has a dedicated PLL for each display controller, hence the PLL rate can be changed freely. Allow PLL rate changes on Tegra30+ for RGB output. Configure the clock rate before display controller is enabled since DC itself may be running off this PLL and it's not okay to change the rate of the active PLL that doesn't support dynamic frequency switching since hardware will hang.

2021-12-16drm/tegra: gr2d: Explicitly control module resetThierry Reding
As of commit 4782c0a5dd88 ("clk: tegra: Don't deassert reset on enabling clocks"), module resets are no longer automatically deasserted when the module clock is enabled. To make sure that the gr2d module continues to work, we need to explicitly control the module reset.

2021-12-16drm/tegra: dc: rgb: Move PCLK shifter programming to CRTCDmitry Osipenko
Asus TF700T tablet uses TC358768 DPI->DSI bridge that sits between Tegra's DPI output and display panel input. Bridge requires to have stable PCLK output before RGB encoder is enabled because it uses PCLK by itself to clock internal logic and bridge is programmed before Tegra's encoder is enabled. Hence the PCLK clock shifter must be programmed when CRTC is enabled, otherwise clock is unstable and bridge hangs because of it. Move the shifter programming from RGB encoder into CRTC.

2021-12-16drm/tegra: Do not reference tegra_plane_funcs directlyThierry Reding

2021-12-16drm/tegra: Implement buffer object cacheThierry Reding
This cache is used to avoid mapping and unmapping buffer objects unnecessarily. Mappings are cached per client and stay hot until the buffer object is destroyed. Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-12-16drm/tegra: Implement correct DMA-BUF semanticsThierry Reding
DMA-BUF requires that each device that accesses a DMA-BUF attaches to it separately. To do so the host1x_bo_pin() and host1x_bo_unpin() functions need to be reimplemented so that they can return a mapping, which either represents an attachment or a map of the driver's own GEM object.
