2024-05-17drm/radeon: initialize backlight for iMac12,2 with Radeon 6750MKendall Smith1-1/+1
If a Radeon 6750M GPU from an iMac12,1 is installed into an iMac 12,2, there is no backlight device initialized during boot. Everything else is functional, but the display brightness cannot be controlled. There are no directories present in /sys/class/backlight after booting. A simple one line modification to an if statement fixes this issue by initializing the radeon backlight device for an iMac12,2 as well if it has a 6750M. After the patch, brightness can be controlled and radeon_bl0 is present in /sys/class/backlight. This was tested by compiling the latest kernel with and without the patch.

2024-05-17regmap: kunit: Fix array overflow in stride() testRichard Fitzgerald1-1/+8
Force the max_register of the test regmap to be one register longer than the number of test registers, to prevent an array overflow in the test loop. The test defines num_reg_defaults = 6. With 6 registers and stride == 2 the valid register addresses would be 0, 2, 4, 6, 8, 10. However the loop checks attempting to access the odd address, so on the final register it accesses address 11, and it writes entry [11] of the read/written arrays. Originally this worked because the max_register of the regmap was hardcoded to be BLOCK_TEST_SIZE (== 12). commit 710915743d53 ("regmap: kunit: Run sparse cache tests at non-zero register addresses") introduced the ability to start the test address range from any address, which means adjusting the max_register. If max_register was not forced, it was calculated either from num_reg_defaults or BLOCK_TEST_SIZE. This correctly calculated that with num_reg_defaults == 6 and stride == 2 the final valid address is 10. So the read/written arrays are allocated to contain entries [0..10]. When stride attempted to access [11] it was overflowing the array.

2024-05-17drm/xe: Replace RING_START_UDW by u64 RING_STARTJosé Roberto de Souza2-8/+6
Other u64 registers are printed in a single line so RING_START needs to follow that too. As there is no upstream decoder tool parsing RING_START this will not break any decoder application.
