We resync the FIFO after each pipe update in apply_ctx_to_hw. However, this means that some pipes (in hardware) are based on the new context and some are based on the current_state (since the pipes are updated on at a time).

2024-07-23drm/amd/display: fix dscclk programming sequence on DCN401Wenjing Liu
[why] The mux to switch between refclk and dto_dsc_clk is non double buffered. However dto dsc clk's phase and modulo divider registers are currently configured as double buffered update. This causes a problem when we switch to use dto dsc clk and program phase and modulo in the same sequence. In this sequence dsc clk is switched to dto but the clock divider programming doesn't take effect until next frame. When we try to program DSCC registers, SMN bus will hang because dto dsc clk divider phase is set to 0. [how] Configure phase and modulo to take effect immediately. Always switch to dto dsc clk before DSC clock is unagted. Switch back to refclk after DSC clock is gated.

2024-07-23drm/xe: Return -ENOBUFS if a kmalloc fails which is tied to an array of bindsMatthew Brost
The size of an array of binds is directly tied to several kmalloc in the KMD, thus making these kmalloc more likely to fail. Return -ENOBUFS in the case of these failures. The expected UMD behavior upon returning -ENOBUFS is to split an array of binds into a series of single binds. v2: - Resend for CI v3: - Resend for CI Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com> Reviewed-by: Jonathan Cavitt <jonathan.cavitt@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240723011702.1684013-1-matthew.brost@intel.com
