drm/nouveau/acr: Fix undefined behavior in nvkm_acr_hsfw_load_bl()
In nvkm_acr_hsfw_load_bl(), the return value of kmalloc() is directly
passed to memcpy(), which could lead to undefined behavior on failure
of kmalloc().
Fix this bug by using kmemdup() instead of kmalloc()+memcpy().
This bug was found by a static analyzer.
Builds with 'make allyesconfig' show no new warnings,
and our static analyzer no longer warns about this code.

drm/edid: Split deep color modes between RGB and YUV444
The current code assumes that the RGB444 and YUV444 formats are the
same, but the HDMI 2.0 specification states that:
The three DC_XXbit bits above only indicate support for RGB 4:4:4 at
that pixel size. Support for YCBCR 4:4:4 in Deep Color modes is
indicated with the DC_Y444 bit. If DC_Y444 is set, then YCBCR 4:4:4
is supported for all modes indicated by the DC_XXbit flags.
So if we have YUV444 support and any DC_XXbit flag set but the DC_Y444
flag isn't, we'll assume that we support that deep colour mode for
YUV444 which breaks the specification.
In order to fix this, let's split the edid_hdmi_dc_modes field in struct
drm_display_info into two fields, one for RGB444 and one for YUV444.

drm/edid: Don't clear formats if using deep color
The current code, when parsing the EDID Deep Color depths, that the
YUV422 cannot be used, referring to the HDMI 1.3 Specification.
This specification, in its section 6.2.4, indeed states:
For each supported Deep Color mode, RGB 4:4:4 shall be supported and
optionally YCBCR 4:4:4 may be supported.
YCBCR 4:2:2 is not permitted for any Deep Color mode.
This indeed can be interpreted like the code does, but the HDMI 1.4
specification further clarifies that statement in its section 6.2.4:
For each supported Deep Color mode, RGB 4:4:4 shall be supported and
optionally YCBCR 4:4:4 may be supported.
YCBCR 4:2:2 is also 36-bit mode but does not require the further use
of the Deep Color modes described in section 6.5.2 and 6.5.3.
This means that, even though YUV422 can be used with 12 bit per color,
it shouldn't be treated as a deep color mode.
This is also broken with YUV444 if it's supported by the display, but
DRM_EDID_HDMI_DC_Y444 isn't set. In such a case, the code will clear
color_formats of the YUV444 support set previously in
drm_parse_cea_ext(), but will not set it back.
Since the formats supported are already setup properly in
drm_parse_cea_ext(), let's just remove the code modifying the formats in

mgag200 fix memmapsl configuration in GCTL6 register
On some servers with MGA G200_SE_A (rev 42), booting with Legacy BIOS,
the hardware hangs when using kdump and kexec into the kdump kernel.
This happens when the uncompress code tries to write "Decompressing Linux"
to the VGA Console.
It can be reproduced by writing to the VGA console (0xB8000) after
booting to graphic mode, it generates the following error:
kernel:NMI: PCI system error (SERR) for reason a0 on CPU 0.
kernel:Dazed and confused, but trying to continue
The root cause is the configuration of the MGA GCTL6 register
According to the GCTL6 register documentation:
bit 0 is gcgrmode:
0: Enables alpha mode, and the character generator addressing system is
activated.
1: Enables graphics mode, and the character addressing system is not
used.
bit 1 is chainodd even:
0: The A0 signal of the memory address bus is used during system memory
addressing.
1: Allows A0 to be replaced by either the A16 signal of the system
address (ifmemmapsl is ‘00’), or by the hpgoddev (MISC<5>, odd/even
page select) field, described on page 3-294).
bit 3-2 are memmapsl:
Memory map select bits 1 and 0. VGA.
These bits select where the video memory is mapped, as shown below:
00 => A0000h - BFFFFh
01 => A0000h - AFFFFh
10 => B0000h - B7FFFh
11 => B8000h - BFFFFh
bit 7-4 are reserved.
Current code set it to 0x05 => memmapsl to b01 => 0xa0000 (graphic mode)
But on x86, the VGA console is at 0xb8000 (text mode)
In arch/x86/boot/compressed/misc.c debug strings are written to 0xb8000
As the driver doesn't use this mapping at 0xa0000, it is safe to set it to
0xb8000 instead, to avoid kernel hang on G200_SE_A rev42, with kexec/kdump.
Thus changing the value 0x05 to 0x0d

drm/panfrost: initial dual core group GPUs support
On a dual core group GPUs (such as T628) fragment shading can be
performed over all cores (because a fragment shader job doesn't
need coherency between threads), however vertex shading requires
to be run on the same core group as the tiler (which always lives
in core group 0).
As a first step to support T628 power on only the first core group
(so no jobs are scheduled on the second one). This makes T628 look
like every other Midgard GPU (and throws away up to half the cores).
With this patch panfrost is able to drive T628 (r1p0) GPU on some
armv8 SoCs (in particular BE-M1000). Without the patch rendering
is horribly broken (desktop is completely unusable) and eventually
the GPU locks up (it takes from a few seconds to a couple of
minutes).
Using the second core group requires support in Mesa (and an UABI
change): the userspace should
1) set PANFROST_JD_DOESNT_NEED_COHERENCY_ON_GPU flag to opt-in
to allowing the job to run across all cores.
2) set PANFROST_RUN_ON_SECOND_CORE_GROUP flag to allow compute
jobs to be run on the second core group (at the moment Mesa
does not advertise compute support on anything older than
Mali T760)
But there's little point adding such flags until someone (myself)
steps up to do the Mesa work.

drm/panfrost: Remove features meant for userspace
Early versions of the legacy kernel driver included comprehensive
feature lists for every GPU, even though most of the enumerated features
only matter to userspace. For example, HW_FEATURE_INTERPIPE_REG_ALIASING
was a feature bit indicating that a GPU had "interpipe register
aliasing": arithmetic, load/store, and texture instruction all use
common general-purpose registers. GPUs without this feature bit have
dedicated load/store and texture "registers". Whether a GPU has this
feature or not is irrelevant to the kernel; it only matters in the
userspace compiler's register allocator. It's silly to enumerate it in
kernel space, and the information is understandably unused. To
underscore the point, this feature only makes sense in the context of
the Midgard instruction set. Bifrost never had dedicated load/store or
texture registers, so the feature bit was vacuously set for all Bifrost
hardware, even though this conveys no useful information.
To clean up the feature list, delete feature bits which could not
possibly matter to the kernel, leaving only those which do affect the
register-level operation of the chip.

In practise, I found that ACPI drivers are bound to their devices AFTER
the drm probe on chromebooks. So on chromebooks with privacy-screen,
this patch along with the other one in this series results in a probe
deferral of about 250ms for i915 driver. However, it did not result in
any user noticeable delay of splash screen in my personal experience.
In future if this probe deferral turns out to be an issue, we can
consider turning this ACPI driver into something that is probed
earlier than the drm drivers.

drm/privacy_screen: Add drvdata in drm_privacy_screen
Allow a privacy screen provider to stash its private data pointer in the
drm_privacy_screen, and update the drm_privacy_screen_register() call to
accept that. Also introduce a *_get_drvdata() so that it can retrieved
back when needed.
This also touches the IBM Thinkpad platform driver, the only user of
privacy screen today, to pass NULL for now to the updated API.

drm: bridge: adv7511: Fix ADV7535 HPD enablement
Existing HPD enablement logic is not compatible with ADV7535
bridge, thus any runtime plug-in of HDMI cable is not working
on these bridge designs.
Unlike other ADV7511 family of bridges, the ADV7535 require
HPD_OVERRIDE bit to set and reset for proper handling of HPD
functionality.
Fix it.
