LoongArch maintains cache coherency in hardware, but its WUC attribute
(Weak-ordered UnCached, which is similar to WC) is out of the scope of
cache coherency machanism. This means WUC can only used for write-only
memory regions.

When building the kernel for arm with the "-mabi=apcs-gnu" option, gcc
will force alignment of all structures and unions to a word boundary
(see also STRUCTURE_SIZE_BOUNDARY and the "-mstructure-size-boundary=XX"
option if you're a gcc person), even when the members of said structures
do not want or need said alignment.
This completely messes up the structure alignment of 'struct edid' on
those targets, because even though all the embedded structures are
marked with "__attribute__((packed))", the unions that contain them are
not.
This was exposed by commit f1e4c916f97f ("drm/edid: add EDID block count
and size helpers"), but the bug is pre-existing. That commit just made
the structure layout problem cause a build failure due to the addition
of the
BUILD_BUG_ON(sizeof(*edid) != EDID_LENGTH);
sanity check in drivers/gpu/drm/drm_edid.c:edid_block_data().
This legacy union alignment should probably not be used in the first
place, but we can fix the layout by adding the packed attribute to the
union entries even when each member is already packed and it shouldn't
matter in a sane build environment.
You can see this issue with a trivial test program:
union {
struct {
char c[5];
};
struct {
char d;
unsigned e;
} __attribute__((packed));
} a = { "1234" };
where building this with a normal "gcc -S" will result in the expected
5-byte size of said union:
.type a, @object
.size a, 5
but with an ARM compiler and the old ABI:
arm-linux-gnu-gcc -mabi=apcs-gnu -mfloat-abi=soft -S t.c
you get
.type a, %object
.size a, 8
instead, because even though each member of the union is packed, the
union itself still gets aligned.
This was reported by Sudip for the spear3xx_defconfig target.

Rename various instances of pagelist to pagereflist. The list now
stores pageref structures, so the new name is more appropriate.
In their write-back helpers, several fbdev drivers refer to the
pageref list in struct fb_deferred_io instead of using the one
supplied as argument to the function. Convert them over to the
supplied one. It's the same instance, so no change of behavior
occurs.

drm_gem_plane_helper_prepare_fb() was using
drm_atomic_set_fence_for_plane() which ignores all implicit fences when an
explicit fence is already set. That's rather unfortunate when the fb still
has a kernel fence we need to wait for to avoid presenting garbage on the
screen.
So instead update the fence in the plane state directly. While at it also
take care of all potential GEM objects and not just the first one.
Also remove the now unused drm_atomic_set_fence_for_plane() function, new
drivers should probably use the atomic helpers directly.
v2: improve kerneldoc, use local variable and num_planes, WARN_ON_ONCE
on missing planes.

Move DRM's HMDI helpers into the display/ subdirectoy and add it
to DRM's display helpers. Update all affected drivers. No functional
changes.
The HDMI helpers were implemented in the EDID and connector code, but
are actually unrelated. With the move to the display-helper library, we
can remove the dependency on drm_edid.{c,h} in some driver's HDMI source
files.
Several of the HDMI helpers remain in EDID code because both share parts
of their implementation internally. With better refractoring of the EDID
code, those HDMI helpers could be moved into the display-helper library
as well.

If we hit the sync case, like when skipping clearing for kernel internal
objects, or when falling back to cpu clearing, like in i915, we end up
trying to add a NULL fence, but with some recent changes in this area
this now just results in NULL deref in dma_resv_add_fence:

In the ttm_bo_move_sync_cleanup() case it seems we only really care
about calling ttm_bo_wait_free_node(), so let's instead just call that

At least some DELL monitors (P2715Q) with DPCD_REV 1.2 return corrupted
DPCD register values when reading from the 0xF0000- LTTPR range with an
AUX transaction block size bigger than 1. The DP standard requires 0 to
be returned - as for any other reserved/invalid addresses - but these
monitors return the DPCD_REV register value repeated in each byte of the
read buffer. This will in turn corrupt the values returned by the LTTPRs
between the source and the monitor: LTTPRs must adjust the values they
read from the downstream DPRX, for instance right-shift/init the
downstream DP_PHY_REPEATER_CNT value. Since the value returned by the
monitor's DPRX is non-zero the adjusted values will be corrupt.
Reading the LTTPR registers one-by-one instead of reading all of them
with a single AUX transfer works around the issue.
According to the DP standard's 0xF0000 register description:
"LTTPR-related registers at DPCD Addresses F0000h through F02FFh are
valid only for DPCD r1.4 (or higher)." While it's unclear if DPCD r1.4
refers to the DPCD_REV or to the
LT_TUNABLE_PHY_REPEATER_FIELD_DATA_STRUCTURE_REV register (tickets filed
at the VESA site to clarify this haven't been addressed), one
possibility is that it's a restriction due to non-compliant monitors
described above. Disabling the non-transparent LTTPR mode for all such
monitors is not a viable solution: the transparent LTTPR mode has its
own issue causing link training failures and this would affect a lot of
monitors in use with DPCD_REV < 1.4. Instead this patch works around
the problem by reading the LTTPR common and PHY cap registers one-by-one
for any monitor with a DPCD_REV < 1.4.
The standard requires the DPCD capabilities to be read after the LTTPR
common capabilities are read, so re-read the DPCD capabilities after
the LTTPR common and PHY caps were read out.
v2:
- Use for instead of a while loop. (Ville)
- Add to code comment the monitor model with the problem.
