This adds the initial driver for panfrost which supports Arm Mali Midgard and Bifrost family of GPUs. Currently, only the T860 and T760 Midgard GPUs have been tested. v2: - Add GPU reset on job hangs (Tomeu) - Add RuntimePM and devfreq support (Tomeu) - Fix T760 support (Tomeu) - Add a TODO file (Rob, Tomeu) - Support multiple in fences (Tomeu) - Drop support for shared fences (Tomeu) - Fill in MMU de-init (Rob) - Move register definitions back to single header (Rob) - Clean-up hardcoded job submit todos (Rob) - Implement feature setup based on features/issues (Rob) - Add remaining Midgard DT compatible strings (Rob) v3: - Add support for reset lines (Neil) - Add a MAINTAINERS entry (Rob) - Call dma_set_mask_and_coherent (Rob) - Do MMU invalidate on map and unmap. Restructure to do a single operation per map/unmap call. (Rob) - Add a missing explicit padding to struct drm_panfrost_create_bo (Rob) - Fix 0-day error: "panfrost_devfreq.c:151:9-16: ERROR: PTR_ERR applied after initialization to constant on line 150" - Drop HW_FEATURE_AARCH64_MMU conditional (Rob) - s/DRM_PANFROST_PARAM_GPU_ID/DRM_PANFROST_PARAM_GPU_PROD_ID/ (Rob) - Check drm_gem_shmem_prime_import_sg_table() error code (Rob) - Re-order power on sequence (Rob) - Move panfrost_acquire_object_fences() before scheduling job (Rob) - Add NULL checks on array pointers in job clean-up (Rob) - Rework devfreq (Tomeu) - Fix devfreq init with no regulator (Rob) - Various WS and comments clean-up (Rob) Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <maxime.ripard@bootlin.com> Cc: Sean Paul <sean@poorly.run> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Lyude Paul <lyude@redhat.com> Reviewed-by:

Similar to the single handle drm_gem_object_lookup(), drm_gem_objects_lookup() takes an array of handles and returns an array of GEM objects. v2: - Take the userspace pointer directly and allocate the array. - Expand the function documentation.

ARM Mali midgard GPU is similar to standard 64-bit stage 1 page tables, but have a few differences. Add a new format type to represent the format. The input address size is 48-bits and the output address size is 40-bits (and possibly less?). Note that the later bifrost GPUs follow the standard 64-bit stage 1 format. The differences in the format compared to 64-bit stage 1 format are: The 3rd level page entry bits are 0x1 instead of 0x3 for page entries. The access flags are not read-only and unprivileged, but read and write. This is similar to stage 2 entries, but the memory attributes field matches stage 1 being an index. The nG bit is not set by the vendor driver. This one didn't seem to matter, but we'll keep it aligned to the vendor driver. Cc: Will Deacon <will.deacon@arm.com> Acked-by:

Due to copy/paste error, the fbdev format was changed to 32bpp = XRGB8888 which is an emulated format for the RGB565 drivers. Revert to to using the fallback which is dev->mode_config.preferred_depth for the drivers that set it or 32bpp for those that don't (repaper, st7586).

Now that we can express our DMA topology, rely on those property instead of hardcoding an offset from the dma_addr_t which wasn't really great. We still need to add some code to deal with the old DT that would lack that property, but we move the offset to the DRM device dma_pfn_offset to be able to rely on just the dma_addr_t associated to the GEM object.

Not all archs have the __io_virt() macro, so cirrus can't simply convert pointers that way. The drm format helpers have to use memcpy_toio() instead. This patch makes drm_fb_xrgb8888_to_rgb888_dstclip() accept a __iomem dst pointer and use memcpy_toio() instead of memcpy(). The helper function (drm_fb_xrgb8888_to_rgb888_line) has been changed to process a single scanline. Signed-off-by:

The Amlogic G12A embeds the same Synopsys DW-HDMI Controller, but with : - a "backport" of the HDR signaling registers from more recent DW-HDMI controllers, this will need a tweak since it's not normally present on this version of the DW-HDMI controller - A direct mapping of TOP and DW-HDMI registers instead of an internal bus accessed using read/write registers - Support for RX-SENSE, but not yet implemented - Support for HDMI 2.1 Dynamic HDR, but not yet implemented - Different registers mapping for the HDMI PHY setup This patchs adds support for these changes while providing exact same support as the previous GXBB, GXL & GXM SoCs.

While switching to the Common Clock Framework is still Work In Progress, this patch adds the corresponding G12A HDMI PLL setup to be on-par with the other SoCs support. The G12A has only a single tweak about the high frequency setup, where the HDMI PLL needs a specific setup to handle correctly the 5.94GHz DCO frequency. Apart that, it handls ecorrectly all the other HDMI frequencies and can achieve even better DMT clock frequency precision with the larger fractional dividier width. Signed-off-by:

On Amlogic G12A SoC, the 2,97GHz PLL frequency is not stable enough to provide a correct 297MHz pixel clock, so switch the PLL base frequency with a /2 OD when the 297MHz pixel clock is requested. This solves the issue on G12A and also works fine on GXBB, GXL & GXM. Signed-off-by:

Add the bindings for the Bifrost family of ARM Mali GPUs. The Bifrost GPU architecture is similar to the Midgard family, but with a different Shader Core & Execution Engine structures. Bindings are based on the Midgard family bindings, but the inner architectural changes makes it a separate family needing separate bindings. The Bifrost GPUs are present in a number of recent SoCs, like the Amlogic G12A Family, and many other vendors. The Amlogic vendor specific compatible is added to handle the specific IP integration differences and dependencies. Signed-off-by:

Time to kill some bad sample code people are copying from ;) This is a complete rewrite of the cirrus driver. The cirrus_mode_set() function is pretty much the only function which is carried over largely unmodified. Everything else is upside down. It is a single monster patch. But given that it does some pretty fundamental changes to the drivers workflow and also reduces the code size by roughly 70% I think it'll still be alot easier to review than a longish baby-step patch series. Changes summary: - Given the small amout of video memory (4 MB) the cirrus device has the rewritten driver doesn't try to manage buffers there. Instead it will blit (memcpy) the active framebuffer to video memory. - All gem objects are stored in main memory and are manged using the new shmem helpers. ttm is out. - It supports RG16, RG24 and XR24 formats. XR24 gets converted to RG24 or RG16 at blit time if needed, to avoid the pitch becoming larger than what the cirrus hardware can handle. - The simple display pipeline is used. - The generic fbdev emulation is used. - It's a atomic driver now. - It runs wayland.
