memory access is blocked. Hence vcpu bo cannot be saved to system memory
as in a regular suspend sequence before going for reset. In other full

Clang on LoongArch (18+) appears to be unaffected by the bug causing
excessive stack usage in calculate_bandwidth(). But when building DC_FP
support the stack frame size can be as large as 2816 bytes, which causes
the FRAME_WARN build warnings. So on LoongArch we allow building DC with
clang, but disable DC_FP by default.
The help message is also updated.

This commit addresses a null pointer dereference issue in
hwss_setup_dpp(). The issue could occur when pipe_ctx->plane_state is
null. The fix adds a check to ensure `pipe_ctx->plane_state` is not null
before accessing. This prevents a null pointer dereference.

This commit addresses a null pointer dereference issue in
dcn20_program_pipe(). Previously, commit 8e4ed3cf16 ("drm/amd/display:
Add null check for pipe_ctx->plane_state in dcn20_program_pipe")
partially fixed the null pointer dereference issue. However, in
dcn20_update_dchubp_dpp(), the variable pipe_ctx is passed in, and
plane_state is accessed again through pipe_ctx. Multiple if statements
directly call attributes of plane_state, leading to potential null
pointer dereference issues. This patch adds necessary null checks to
ensure stability.

On several HP models (tested on HP 3125 and HP Probook 455 G2),
spurious unplug events are emitted upon login on Chrome OS.
This is likely due to the way Chrome OS restarts graphics
upon login, so it's possible it's an issue on other
distributions but not as common, though I haven't
reproduced the issue elsewhere.
Use logic from an earlier version of the merged change
(see link below) which iterates over connectors and finds
matching encoders, rather than the other way around.
Also fixes an issue with screen mirroring on Chrome OS.
I've deployed this patch on Fedora and did not observe

for all IPs to be initialized before a reset. In such cases, it needs to
identify whether the IP/feature is initialized for the first time or
whether it's reinitialized after a reset.

phase. This only provides a device level identification, IP/features may

There are cases where an OTG is remapped from driving a regular HDMI
display to a DP/eDP display. There are also cases where DTBCLK needs to
be enabled for HPO, but DTBCLK DTO programming may be done while OTG is
still enabled which is dangerous as the PIPE_DTO_SRC_SEL programming may
change the pixel clock generator source for a mapped and running OTG and
cause it to hang.
Remove the PIPE_DTO_SRC_SEL programming from this sequence since it is
already done in program_pixel_clk(). Additionally, make sure that
program_pixel_clk sets DTBCLK DTO as source for special HDMI cases.

The mechanism to backup and restore plane states doesn't maintain
refcount, which can cause issues if the refcount of the plane changes

accesses if the refcount was supposed to go up.
[How]
Cache and re-apply current refcount when restoring plane states.
