2025-01-13drm/i915/fb: Relax clear color alignment to 64 bytesVille Syrjälä
Mesa changed its clear color alignment from 4k to 64 bytes without informing the kernel side about the change. This is now likely to cause framebuffer creation to fail. The only thing we do with the clear color buffer in i915 is: 1. map a single page 2. read out bytes 16-23 from said page 3. unmap the page So the only requirement we really have is that those 8 bytes are all contained within one page. Thus we can deal with the Mesa regression by reducing the alignment requiment from 4k to the same 64 bytes in the kernel. We could even go as low as 32 bytes, but IIRC 64 bytes is the hardware requirement on the 3D engine side so matching that seems sensible. Note that the Mesa alignment chages were partially undone so the regression itself was already fixed on userspace side.

2025-01-13drm/i915/guc/slpc: Allow GuC SLPC default strategies on MTL+Rodrigo Vivi
The Balancer and DCC strategies were left off on a fear that these strategies would conflict with the i915's waitboost. However, on MTL and Beyond these strategies are only active in certain conditions where the system is TDP limited. So, they don't conflict, but help the waitboost by guaranteeing a bit more of GT frequency. Without these strategies we were likely leaving some performance behind on some scenarios. With this change in place, the enabling/disabling of DCC and Balancer will now be chosen by GuC, on a platform/GT basis. v2: - Fix typos and be clear on GuC decision on platform basis (Vinay) - Limit change to MTL and beyond, where GuC started to take TDP limit into consideration. v3: Fix compilation.

2025-01-13drm/panel-edp: Add Starry 116KHD024006Douglas Anderson
We have a few reports of sc7180-trogdor-pompom devices that have a panel in them that IDs as STA 0x0004 and has the following raw EDID: 00 ff ff ff ff ff ff 00 4e 81 04 00 00 00 00 00 10 20 01 04 a5 1a 0e 78 0a dc dd 96 5b 5b 91 28 1f 52 54 00 00 00 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 8e 1c 56 a0 50 00 1e 30 28 20 55 00 00 90 10 00 00 18 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 fe 00 31 31 36 4b 48 44 30 32 34 30 30 36 0a 00 e6 We've been unable to locate a datasheet for this panel and our partner has not been responsive, but all Starry eDP datasheets that we can find agree on the same timing (delay_100_500_e200) so it should be safe to use that here instead of the super conservative timings. We'll still go a little extra conservative and allow `hpd_absent` of 200 instead of 100 because that won't add any real-world delay in most cases. We'll associate the string from the EDID ("116KHD024006") with this panel. Given that the ID is the suspicious value of 0x0004 it seems likely that Starry doesn't always update their IDs but the string will still work to differentiate if we ever need to in the future.

2025-01-13nouveau/fence: handle cross device fences properlyDave Airlie
The fence sync logic doesn't handle a fence sync across devices as it tries to write to a channel offset from one device into the fence bo from a different device, which won't work so well. This patch fixes that to avoid using the sync path in the case where the fences come from different nouveau drm devices. This works fine on a single device as the fence bo is shared across the devices, and mapped into each channels vma space, the channel offsets are therefore okay to pass between sides, so one channel can sync on the seqnos from the other by using the offset into it's vma.

2025-01-13drm/ttm/pool: Restructure the pool allocation codeThomas Hellström
Simplify the pool allocation code somewhat by merging loop arguments used by multiple functions together in a struct and simplifying the loop. Also add documentation. This hopefully makes the behaviour of the allocation loop simplier to understand, but above all paves the way for upcoming restore-while-allocating functionality. There are no functional changes, but the "allow_pools" bool introduced to keep current functionality could be removed as a follow up, which would enable using write-back cached pools when allocating memory for other caching modes, rather than to resort to allocating from the system directly. v15: - Introduce this patch to simplify the upcoming patch that introduces restore while allocating.

Current live_rps_control() implementation errors out on throttling. This was done with the assumption that throttling to minimum frequency is a catastrophic failure, which is incorrect. Throttling can happen due to variety of reasons and often times out of our control. Also, the resulting frequency can be at any given point below the maximum allowed. Change throttle criteria to reflect this logic and drop the error, as it doesn't necessarily mean selftest failure.

2025-01-10drm/amd/display: Do not elevate mem_type change to full updateLeo Li
[Why] There should not be any need to revalidate bandwidth on memory placement change, since the fb is expected to be pinned to DCN-accessable memory before scanout. For APU it's DRAM, and DGPU, it's VRAM. However, async flips + memory type change needs to be rejected. [How] Do not set lock_and_validation_needed on mem_type change. Instead, reject an async_flip request if the crtc's buffer(s) changed mem_type. This may fix stuttering/corruption experienced with PSR SU and PSR1 panels, if the compositor allocates fbs in both VRAM carveout and GTT and flips between them.

2025-01-10drm/amd/display: Do not wait for PSR disable on vbl enableLeo Li
[Why] Outside of a modeset/link configuration change, we should not have to wait for the panel to exit PSR. Depending on the panel and it's state, it may take multiple frames for it to exit PSR. Therefore, waiting in all scenarios may cause perceived stuttering, especially in combination with faster vblank shutdown. [How] PSR1 disable is hooked up to the vblank enable event, and vice versa. In case of vblank enable, do not wait for panel to exit PSR, but still wait in all other cases. We also avoid a call to unnecessarily change power_opts on disable - this ends up sending another command to dmcub fw. When testing against IGT, some crc tests like kms_plane_alpha_blend and amd_hotplug were failing due to CRC timeouts. This was found to be caused by the early return before HW has fully exited PSR1. Fix this by first making sure we grab a vblank reference, then waiting for panel to exit PSR1, before programming hw for CRC generation.
