2022-11-02drm/msm/dpu: Refactor sc7280_pp locationRobert Foss
The sc7280_pp declaration is not located by the other _pp declarations, but rather hidden around the _merge_3d declarations. Let's fix this to avoid confusion.

2022-10-20drm/amdgpu: fix sdma doorbell init ordering on APUsAlex Deucher
Commit 8795e182b02d ("PCI/portdrv: Don't disable AER reporting in get_port_device_capability()") uncovered a bug in amdgpu that required a reordering of the driver init sequence to avoid accessing a special register on the GPU before it was properly set up leading to an PCI AER error. This reordering uncovered a different hw programming ordering dependency in some APUs where the SDMA doorbells need to be programmed before the GFX doorbells. To fix this, move the SDMA doorbell programming back into the soc15 common code, but use the actual doorbell range values directly rather than the values stored in the ring structure since those will not be initialized at this point. This is a partial revert, but with the doorbell assignment fixed so the proper doorbell index is set before it's used.

2022-10-20drm/panfrost: replace endian-specific types with native onesSteven Price
__le32 and __le64 types aren't portable and are not available on FreeBSD (which uses the same uAPI). Instead of attempting to always output little endian, just use native endianness in the dumps. Tools can detect the endianness in use by looking at the 'magic' field, but equally we don't expect big-endian to be used with Mali (there are no known implementations out there).

2022-10-20drm/connector: Set DDC pointer in drmm_connector_initMaxime Ripard
Commit 35a3b82f1bdd ("drm/connector: Introduce drmm_connector_init") introduced the function drmm_connector_init() with a parameter for an optional ddc pointer to the i2c controller used to access the DDC bus. However, the underlying call to __drm_connector_init() was always setting it to NULL instead of passing the ddc argument around. This resulted in unexpected null pointer dereference on platforms expecting to get a DDC controller.

2022-10-20drm: tests: Fix a buffer overflow in format_helper_testDavid Gow
The xrgb2101010 format conversion test (unlike for other formats) does an endianness conversion on the results. However, it always converts TEST_BUF_SIZE 32-bit integers, which results in reading from (and writing to) more memory than in present in the result buffer. Instead, use the buffer size, divided by sizeof(u32). The issue could be reproduced with KASAN: ./tools/testing/kunit/kunit.py run --kunitconfig drivers/gpu/drm/tests \ --kconfig_add CONFIG_KASAN=y --kconfig_add CONFIG_KASAN_VMALLOC=y \ --kconfig_add CONFIG_KASAN_KUNIT_TEST=y \ drm_format_helper_test.*xrgb2101010 Reported-by: Linux Kernel Functional Testing <lkft@linaro.org> Fixes: 453114319699 ("drm/format-helper: Add KUnit tests for drm_fb_xrgb8888_to_xrgb2101010()") Signed-off-by: David Gow <davidgow@google.com> Reviewed-by: Maíra Canal <mairacanal@riseup.net> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: José Expósito <jose.exposito89@gmail.com> Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221019073239.3779180-1-davidgow@google.com

The fb_base in struct drm_mode_config has been unused for a long time. Some drivers set it and some don't leading to a very confusing state where the variable can't be relied upon, because there's no indication as to which driver sets it and which doesn't.

For now the zynqmp_dp_bridge_attach() is called manually at initialization time. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
