Marijn Suijten 7557f58b63 drm/msm/dpu: Set PINGPONG block length to zero for DPU >= 7.0.0
Despite downstream DTS stating otherwise, the PINGPONG block has no
registers starting with DPU revision 7.0.0.  TEAR registers are gone
since DPU 5.0.0 after being moved to the INTF block, and DSC registers
are gone since 7.0.0, leaving only the dither sub-block.

A future patch, part of the DSC 1.2 series, should disable DSC functions
on the PINGPONG block for all DPU >= 7.0.0 hardware.

Marijn Suijten fe47a30847 drm/msm/dpu: Use V2 DITHER PINGPONG sub-block in SM8[34]50/SC8280XP
According to downstream sources this DITHER sub-block sits at an offset
of 0xe0 with version 0x20000. Lets fix this by using sc7280_pp_sblk
instead of sdm845_pp_sblk.

Marijn Suijten 701f69183d drm/msm/dpu: Fix PP_BLK_DIPHER -> DITHER typo
SM8550 exclusively has a DITHER sub-block inside the PINGPONG block and
no other registers, hence the DITHER name of the macro and a
corresponding PINGPONG block length of zero.  However, the PP_BLK_ macro
name was typo'd to DIPHER rather than DITHER.

Marijn Suijten cfbc21d1c0 drm/msm/dpu: Remove TE2 block and feature from DPU >= 5.0.0 hardware
No hardware beyond kona (sm8250, DPU 6.0.0) defines the TE2 PINGPONG
sub-block offset downstream, and according to insiders no DPU >= 5.0.0
hardware has support for it either.  Especially since neither downstream
nor upstream utilize these registers in any way, remove the erroneous
specification from SM8150, SC8180X, SM8250, SC7180, SM8350, SC8280XP and
SM8450 to prevent confusion.

Note that downstream enables the PPSPLIT (split-FIFO) topology (single
LM for 2 PP and 2 INTF) based on the presence of a TE2 block.

Arnaud Vrac 686eb89b10 drm/msm/dpu: tweak lm pairings in msm8998 hw catalog
Change lm blocks pairs so that lm blocks with the same features are
paired together:

LM_0 and LM_1 with PP and DSPP
LM_2 and LM_5 with PP
LM_3 and LM_4

This matches the sdm845 configuration and allows using pp or dspp when 2
lm blocks are needed in the topology. In the previous config the
reservation code could never find an lm pair without a matching feature
set.

Srinivas Kandagatla 85c636284c drm/msm/dp: unregister audio driver during unbind
while binding the code always registers a audio driver, however there
is no corresponding unregistration done in unbind. This leads to multiple
redundant audio platform devices if dp_display_bind and dp_display_unbind
happens multiple times during startup. On X13s platform this resulted in
6 to 9 audio codec device instead of just 3 codec devices for 3 dp ports.

Fix this by unregistering codecs on unbind.

But, as with msm_gem_get_vaddr_active(), this is a special case
because we know that the buffer won't be purged evicted until it's
fence is signaled.  We just forgot to propagate the logic get_vaddr()
to pin_pages_locked().

order to compute a target vblank time for an async commit.  Otherwise
we get this splat reminding us that we are doing it wrong:

Ville Syrjälä d944eafed6 drm/i915: Check pipe source size when using skl+ scalers
The skl+ scalers only sample 12 bits of PIPESRC so we can't
do any plane scaling at all when the pipe source size is >4k.

Make sure the pipe source size is also below the scaler's src
size limits. Might not be 100% accurate, but should at least be
safe. We can refine the limits later if we discover that recent
hw is less restricted.

The is because damage rectangles computed by
drm_fb_helper_memory_range_to_clip() function is not guaranteed to be
bound in the screen's active display area. Possible reasons are:

1) Buffers are allocated in the granularity of page size, for mmap system
   call support. The shadow screen buffer consumed by fbdev emulation may
   also choosed be page size aligned.

2) The DIV_ROUND_UP() used in drm_fb_helper_memory_range_to_clip()
   will introduce off-by-one error.

For example, on a 16KB page size system, in order to store a 1920x1080
XRGB framebuffer, we need allocate 507 pages. Unfortunately, the size
1920*1080*4 can not be divided exactly by 16KB.

 1920 * 1080 * 4 = 8294400 bytes
 506 * 16 * 1024 = 8290304 bytes
 507 * 16 * 1024 = 8306688 bytes

 line_length = 1920*4 = 7680 bytes

 507 * 16 * 1024 / 7680 = 1081.6

 off / line_length = 507 * 16 * 1024 / 7680 = 1081
 DIV_ROUND_UP(507 * 16 * 1024, 7680) will yeild 1082

memcpy_toio() typically issue the copy line by line, when copy the last
line, out-of-bound access will be happen. Because:

 1082 * line_length = 1082 * 7680 = 8309760, and 8309760 > 8306688

Note that userspace may still write to the invisiable area if a larger
buffer than width x stride is exposed. But it is not a big issue as
long as there still have memory resolve the access if not drafting so
far.

 - Also limit the y1 (Daniel)
 - keep fix patch it to minimal (Daniel)
 - screen_size is page size aligned because of it need mmap (Thomas)
 - Adding fixes tag (Thomas)

Alan Liu c8b5a95b57 drm/amdgpu: Fix desktop freezed after gpu-reset
[Why]
After gpu-reset, sometimes the driver fails to enable vblank irq,
causing flip_done timed out and the desktop freezed.

During gpu-reset, we disable and enable vblank irq in dm_suspend() and
dm_resume(). Later on in amdgpu_irq_gpu_reset_resume_helper(), we check
irqs' refcount and decide to enable or disable the irqs again.

However, we have 2 sets of API for controling vblank irq, one is
dm_vblank_get/put() and another is amdgpu_irq_get/put(). Each API has
its own refcount and flag to store the state of vblank irq, and they
are not synchronized.

In drm we use the first API to control vblank irq but in
amdgpu_irq_gpu_reset_resume_helper() we use the second set of API.

The failure happens when vblank irq was enabled by dm_vblank_get()
before gpu-reset, we have vblank->enabled true. However, during
gpu-reset, in amdgpu_irq_gpu_reset_resume_helper() vblank irq's state
checked from amdgpu_irq_update() is DISABLED. So finally it disables
vblank irq again. After gpu-reset, if there is a cursor plane commit,
the driver will try to enable vblank irq by calling drm_vblank_enable(),
but the vblank->enabled is still true, so it fails to turn on vblank
irq and causes flip_done can't be completed in vblank irq handler and
desktop become freezed.

[How]
Combining the 2 vblank control APIs by letting drm's API finally calls
amdgpu_irq's API, so the irq's refcount and state of both APIs can be
synchronized. Also add a check to prevent refcount from being less then
0 in amdgpu_irq_put().

v2:
- Add warning in amdgpu_irq_enable() if the irq is already disabled.
- Call dc_interrupt_set() in dm_set_vblank() to avoid refcount change
  if it is in gpu-reset.

v3:
- Improve commit message and code comments.

 Move function "amdgpu_virt_release_full_gpu()" after function "amdgpu_device_ip_late_init()",
 to ensure that registers be accessed through RLCG instead of KIQ.

Commit 41d351f295 ("drm/nouveau: stop using ttm_bo_wait")
converted from ttm_bo_wait_ctx() to dma_resv_wait_timeout().
However, dma_resv_wait_timeout() returns greater than zero on

will fail and log errors even when it was a success.

Change the return code handling to match that of
nouveau_gem_ioctl_cpu_prep(), which was already using
dma_resv_wait_timeout() correctly.

Sascha Hauer afa965a45e drm/rockchip: vop2: fix suspend/resume
During a suspend/resume cycle the VO power domain will be disabled and
the VOP2 registers will reset to their default values. After that the
cached register values will be out of sync and the read/modify/write
operations we do on the window registers will result in bogus values
written. Fix this by re-initializing the register cache each time we
enable the VOP2. With this the VOP2 will show a picture after a
suspend/resume cycle whereas without this the screen stays dark.

Thomas Zimmermann 49953b70e7 drm/exynos: Implement fbdev emulation as in-kernel client
Move code from ad-hoc fbdev callbacks into DRM client functions
and remove the old callbacks. The functions instruct the client
to poll for changed output or restore the display. The DRM core
calls both, the old callbacks and the new client helpers, from
the same places. The new functions perform the same operation as
before, so there's no change in functionality.

Replace all code that initializes or releases fbdev emulation
throughout the driver. Instead initialize the fbdev client by a
single call to exynos_fbdev_setup() after exynos has registered its
DRM device. As in most drivers, exynos' fbdev emulation now acts
like a regular DRM client.

The fbdev client setup consists of the initial preparation and the
hot-plugging of the display. The latter creates the fbdev device
and sets up the fbdev framebuffer. The setup performs display
hot-plugging once. If no display can be detected, DRM probe helpers
re-run the detection on each hotplug event.

A call to drm_dev_unregister() releases the client automatically.
No further action is required within exynos. If the fbdev framebuffer
has been fully set up, struct fb_ops.fb_destroy implements the
release. For partially initialized emulation, the fbdev client
reverts the initial setup.

Lucas De Marchi d1691bb22e drm/i915/gt: Avoid out-of-bounds access when loading HuC
When HuC is loaded by GSC, there is no header definition for the kernel
to look at and firmware is just handed to GSC. However when reading the
version, it should still check the size of the blob to guarantee it's not
incurring into out-of-bounds array access.

If firmware is smaller than expected, the following message is now
printed:

	# echo boom > /lib/firmware/i915/dg2_huc_gsc.bin
	# dmesg | grep -i huc
	[drm] GT0: HuC firmware i915/dg2_huc_gsc.bin: invalid size: 5 < 184
	[drm] *ERROR* GT0: HuC firmware i915/dg2_huc_gsc.bin: fetch failed -ENODATA
	...

Even without this change the size, header and signature are still
checked by GSC when loading, so this only avoids the out-of-bounds array
access.

For gfx_rings the schedulers may not be initialized by
amdgpu_device_init_schedulers() due to ring->no_scheduler flag being set to
true and thus the timeout_wq is NULL. As a result, since all ASICs call
drm_sched_fault() unconditionally even for schedulers which have not been
initialized, it is simpler to use the ready condition which indicates whether
the given scheduler worker thread runs and whether the timeout_wq of the reset
domain has been initialized.

Mukul Joshi dd29944165 drm/amdgpu: Rework retry fault removal
Rework retry fault removal from the software filter by
storing an expired timestamp for a fault that is being removed.
When a new fault comes, and it matches an entry in the sw filter,
it will be added as a new fault only when its timestamp is greater
than the timestamp expiry of the fault in the sw filter.
This helps in avoiding stale faults being added back into the
filter and preventing legitimate faults from being handled.

Lionel Landwerlin 81900e3a37 drm/i915: disable sampler indirect state in bindless heap
By default the indirect state sampler data (border colors) are stored
in the same heap as the SAMPLER_STATE structure. For userspace drivers
that can be 2 different heaps (dynamic state heap & bindless sampler
state heap). This means that border colors have to copied in 2
different places so that the same SAMPLER_STATE structure find the
right data.

This change is forcing the indirect state sampler data to only be in
the dynamic state pool (more convenient for userspace drivers, they
only have to have one copy of the border colors). This is reproducing
the behavior of the Windows drivers.

Sreekant Somasekharan 00fa40353b drm/amdkfd: Check PCIe atomics support on GFX11 to set CP_HQD_HQ_STATUS0[29]
CP_HQD_HQ_STATUS0[29] bit will be used by CPFW to acknowledge whether
PCIe atomics are supported. The default value of this bit is set
to 0. Driver will check whether PCIe atomics are supported and set the
bit to 1 if supported. This will force CPFW to use real atomic ops.
If the bit is not set, CPFW will default to read/modify/write using the
firmware itself.

This is applicable only to GFX11 RS64 CP with MEC FW >= 509. If MEC
FW < 509 and for all GFX11 F32 CP, PCIe atomics needs to be supported
else it will skip the device.

This commit also involves moving amdgpu_amdkfd_device_probe() function
call after per-IP early_init loop in amdgpu_device_ip_early_init()
function so as to check for RS64 enabled device.

Hans de Goede 67abe9c6a8 ACPI: video: Remove register_backlight_delay module option and code
Since commit 5aa9d943e9 ("ACPI: video: Don't enable fallback path for
creating ACPI backlight by default"), the delayed registering of
acpi_video# backlight devices has been disabled by default.

The few bugreports where this option was used as a workaround were all
cases where the GPU driver did not call acpi_video_register_backlight()
and the workaround was to pass video.register_backlight_delay=1.

With the recent "ACPI: video: Make acpi_backlight=video work independent
from GPU driver" changes acpi_backlight=video can be used to achieve
the same result. So there is no need for the register_backlight_delay
option + code anymore.

vmwgfx should refuse to load on those configurations but currently
drm has no way of reloading fbdev when the specific pci driver refuses
to load, which would leave users without a usable fb. Instead of
refusing to load print an error and disable a bunch of functionality

Michael Ellerman 78f0929884 powerpc/64: Always build with 128-bit long double
The amdgpu driver builds some of its code with hard-float enabled,
whereas the rest of the kernel is built with soft-float.

When building with 64-bit long double, if soft-float and hard-float
objects are linked together, the build fails due to incompatible ABI
tags.

In the past there have been build errors in the amdgpu driver caused by
this, some of those were due to bad intermingling of soft & hard-float
code, but those issues have now all been fixed since commit 58ddbecb14
("drm/amd/display: move remaining FPU code to dml folder").

However it's still possible for soft & hard-float objects to end up
linked together, if the amdgpu driver is built-in to the kernel along
with the test_emulate_step.c code, which uses soft-float. That happens
in an allyesconfig build.

Currently those build errors are avoided because the amdgpu driver is
gated on 128-bit long double being enabled. But that's not a detail the
amdgpu driver should need to be aware of, and if another driver starts
using hard-float the same problem would occur.

All versions of the 64-bit ABI specify that long-double is 128-bits.
However some compilers, notably the kernel.org ones, are built to use
64-bit long double by default.

Apart from this issue of soft vs hard-float, the kernel doesn't care
what size long double is. In particular the kernel using 128-bit long
double doesn't impact userspace's ability to use 64-bit long double, as
musl does.

So always build the 64-bit kernel with 128-bit long double. That should
avoid any build errors due to the incompatible ABI tags. Excluding the
code that uses soft/hard-float, the vmlinux is identical with/without
the flag.

It does mean any code which is incorrectly intermingling soft &
hard-float code will build without error, so those bugs will need to be
caught by testing rather than at build time.

For more background see:
  - commit d11219ad53 ("amdgpu: disable powerpc support for the newer display engine")
  - commit c653c59178 ("drm/amdgpu: Re-enable DCN for 64-bit powerpc")

The driver doesn't use simple-KMS helpers to set a simple display pipeline
but only the drm_simple_encoder_init() function to initialize an encoder.

That helper is just a wrapper of drm_encoder_init(), but passing a struct
drm_encoder_funcs that sets the .destroy handler to drm_encoder_cleanup().

Since the <drm/drm_simple_kms_helper.h> header is only included for this
helper and because the connector is initialized with drm_connector_init()
as well, do the same for the encoder and drop the header include.

Douglas Anderson bfc12020e6 drm/msm/dp: Return IRQ_NONE for unhandled interrupts
If our interrupt handler gets called and we don't really handle the
interrupt then we should return IRQ_NONE. The current interrupt
handler didn't do this, so let's fix it.

NOTE: for some of the cases it's clear that we should return IRQ_NONE
and some cases it's clear that we should return IRQ_HANDLED. However,
there are a few that fall somewhere in between. Specifically, the
documentation for when to return IRQ_NONE vs. IRQ_HANDLED is probably
best spelled out in the commit message of commit d9e4ad5bad ("Document
that IRQ_NONE should be returned when IRQ not actually handled"). That
commit makes it clear that we should return IRQ_HANDLED if we've done
something to make the interrupt stop happening.

The case where it's unclear is, for instance, in dp_aux_isr() after
we've read the interrupt using dp_catalog_aux_get_irq() and confirmed
that "isr" is non-zero. The function dp_catalog_aux_get_irq() not only
reads the interrupts but it also "ack"s all the interrupts that are
returned. For an "unknown" interrupt this has a very good chance of
actually stopping the interrupt from happening. That would mean we've
identified that it's our device and done something to stop them from
happening and should return IRQ_HANDLED. Specifically, it should be
noted that most interrupts that need "ack"ing are ones that are
one-time events and doing an "ack" is enough to clear them. However,
since these interrupts are unknown then, by definition, it's unknown
if "ack"ing them is truly enough to clear them. It's possible that we
also need to remove the original source of the interrupt. In this
case, IRQ_NONE would be a better choice.

Given that returning an occasional IRQ_NONE isn't the absolute end of
the world, however, let's choose that course of action. The IRQ
framework will forgive a few IRQ_NONE returns now and again (and it
won't even log them, which is why we have to log them ourselves). This
means that if we _do_ end hitting an interrupt where "ack"ing isn't
enough the kernel will eventually detect the problem and shut our
device down.

Konrad Dybcio ff83e76b0f drm/msm/dsi: Fix DSI index detection when version clash occurs
Currently, we allow for MAX_DSI entries in io_start to facilitate for
MAX_DSI number of DSI hosts at different addresses. The configuration
is matched against the DSI CTRL hardware revision read back from the
component. We need a way to resolve situations where multiple SoCs
with different register maps may use the same version of DSI CTRL. In
preparation to do so, make msm_dsi_config a 2d array where each entry
represents a set of configurations adequate for a given SoC.

This is totally fine to do, as the only differentiating factors
between same-version-different-SoCs configurations are the number of
DSI hosts (1 or 2, at least as of today) and the set of base registers.
The regulator setup is the same, because the DSI hardware is the same,
regardless of the SoC it was implemented in.

In addition to that, update the matching logic such that it will loop
over VARIANTS_MAX variants, making sure they are all taken into account.

Douglas Anderson b20566cdef drm/msm/dp: Clean up handling of DP AUX interrupts
The DP AUX interrupt handling was a bit of a mess.
* There were two functions (one for "native" transfers and one for
  "i2c" transfers) that were quite similar. It was hard to say how
  many of the differences between the two functions were on purpose
  and how many of them were just an accident of how they were coded.
* Each function sometimes used "else if" to test for error bits and
  sometimes didn't and again it was hard to say if this was on purpose
  or just an accident.
* The two functions wouldn't notice whether "unknown" bits were
  set. For instance, there seems to be a bit "DP_INTR_PLL_UNLOCKED"
  and if it was set there would be no indication.
* The two functions wouldn't notice if more than one error was set.

Let's fix this by being more consistent / explicit about what we're
doing.

By design this could cause different handling for AUX transfers,
though I'm not actually aware of any bug fixed as a result of
this patch (this patch was created because we simply noticed how odd
the old code was by code inspection). Specific notes here:
1. In the old native transfer case if we got "done + wrong address"
   we'd ignore the "wrong address" (because of the "else if"). Now we
   won't.
2. In the old native transfer case if we got "done + timeout" we'd
   ignore the "timeout" (because of the "else if"). Now we won't.
3. In the old native transfer case we'd see "nack_defer" and translate
   it to the error number for "nack". This differed from the i2c
   transfer case where "nack_defer" was given the error number for
   "nack_defer". This 100% can't matter because the only user of this
   error number treats "nack defer" the same as "nack", so it's clear
   that the difference between the "native" and "i2c" was pointless
   here.
4. In the old i2c transfer case if we got "done" plus any error
   besides "nack" or "defer" then we'd ignore the error. Now we don't.
5. If there is more than one error signaled by the hardware it's
   possible that we'll report a different one than we used to. I don't
   know if this matters. If someone is aware of a case this matters we
   should document it and change the code to make it explicit.
6. One quirk we keep (I don't know if this is important) is that in
   the i2c transfer case if we see "done + defer" we report that as a
   "nack". That seemed too intentional in the old code to just drop.

After this change we will add extra logging, including:
* A warning if we see more than one error bit set.
* A warning if we see an unexpected interrupt.
* A warning if we get an AUX transfer interrupt when shouldn't.

It actually turns out that as a result of this change then at boot we
sometimes see an error:
  [drm:dp_aux_isr] *ERROR* Unexpected DP AUX IRQ 0x01000000 when not busy
That means that, during init, we are seeing DP_INTR_PLL_UNLOCKED. For
now I'm going to say that leaving this error reported in the logs is
OK-ish and hopefully it will encourage someone to track down what's
going on at init time.

One last note here is that this change renames one of the interrupt
bits. The bit named "i2c done" clearly was used for native transfers
being done too, so I renamed it to indicate this.
