8f5264d302 drm/msm/adreno: Remove MODULE_FIRMWARE()'s
The driver handles the case where gpu fw is not in the initrd.  OTOH it
doesn't always handle the case where _some_ fw is in the initrd, but
others are not.  In particular the zap fw tends to be signed with an OEM
specific key, so the paths/names differ across devices with the same
SoC/GPU, so we cannot sanely list them with MODULE_FIRMWARE().

So MODULE_FIRMWARE() just ends up causing problems without actually
solving anything.  Remove them!

b733fe7bff drm/msm/adreno: Add support for ACD
ACD a.k.a Adaptive Clock Distribution is a feature which helps to reduce
the power consumption. In some chipsets, it is also a requirement to
support higher GPU frequencies. This patch adds support for GPU ACD by
sending necessary data to GMU and AOSS. The feature support for the
chipset is detected based on devicetree data.

dda72ac390 drm/msm/adreno: Drop fictional address_space_size

4GB to avoid 32b rollover problems in 64b pointer math in older sqe fw.

space to 4GB.  In all other cases, use the SMMU input address size (IAS)

c0134808a9 drm/msm: Be more robust when HFI response times out
If the GMU takes too long to respond to an HFI message, we may return
early. If the GMU does eventually respond, and then we send a second
message, we will see the response for the first, throw another error,
and keep going. But we don't currently wait for the interrupt from the
GMU again, so if the second response isn't there immediately we may
prematurely return. This can cause a continuous cycle of missed HFI
messages, and for reasons I don't quite understand the GMU does not shut
down properly when this happens.

Fix this by waiting for the GMU interrupt when we see an empty queue. If
the GMU never responds then the queue really is empty and we quit. We
can't wait for the interrupt when we see a wrong response seqnum because
the GMU might have already queued both responses by the time we clear
the interrupt the first time so we do need to check the queue before
waiting on the interrupt again.

It was observed on sc7180 (A618 gpu) that GPU votes for GX rail and CNOC
BCM nodes were not removed after GPU suspend. This was because we
skipped sending 'prepare-slumber' request to gmu during suspend sequence
in some cases. So, make sure we always call prepare-slumber hfi during
suspend. Also, calling prepare-slumber without a prior oob-gpu handshake
messes up gmu firmware's internal state. So, do that when required.

7047e655a5 drm/msm: adreno: find bandwidth index of OPP and set it along freq index
The Adreno GPU Management Unit (GMU) can also scale the DDR Bandwidth
along the Frequency and Power Domain level, until now we left the OPP
core scale the OPP bandwidth via the interconnect path.

In order to enable bandwidth voting via the GPU Management
Unit (GMU), when an opp is set by devfreq we also look for
the corresponding bandwidth index in the previously generated
bw_table and pass this value along the frequency index to the GMU.

The GMU also takes another vote called AB which is a 16bit quantized
value of the floor bandwidth against the maximum supported bandwidth.

The AB is calculated with a default 25% of the bandwidth like the
downstream implementation too inform the GMU firmware the minimal
quantity of bandwidth we require for this OPP. Only pass the AB
vote starting from A750 GPUs.

Since we now vote for all resources via the GMU, setting the OPP
is no more needed, so we can completely skip calling
dev_pm_opp_set_opp() in this situation.

Let's dynamically generate the bw_table with the vote values

Those entries will then be used by the GMU when passing the
appropriate bandwidth level while voting for a gpu frequency.

ff4a7f6bff drm/msm: adreno: add plumbing to generate bandwidth vote table for GMU
The Adreno GPU Management Unit (GMU) can also scale DDR Bandwidth along
the Frequency and Power Domain level, but by default we leave the
OPP core scale the interconnect ddr path.

While scaling via the interconnect path was sufficient, newer GPUs
like the A750 requires specific vote paremeters and bandwidth to
achieve full functionality.

In order to calculate vote values used by the GPU Management
Unit (GMU), we need to parse all the possible OPP Bandwidths and
create a vote value to be sent to the appropriate Bus Control
Modules (BCMs) declared in the GPU info struct.

This vote value is called IB, while on the other side the GMU also
takes another vote called AB which is a 16bit quantized value
of the floor bandwidth against the maximum supported bandwidth.
The AB vote will be calculated later when setting the frequency.

The vote array will then be used to dynamically generate the GMU
bw_table sent during the GMU power-up.

e70140ba0d Get rid of 'remove_new' relic from platform driver struct
The continual trickle of small conversion patches is grating on me, and
is really not helping.  Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:

  /*
   * .remove_new() is a relic from a prototype conversion of .remove().
   * New drivers are supposed to implement .remove(). Once all drivers are
   * converted to not use .remove_new any more, it will be dropped.
   */

This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.

I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.

Then I just removed the old (sic) .remove_new member function, and this
is the end result.  No more unnecessary conversion noise.

A few more Qualcomm driver updates for v6.13

Make the Adreno driver invoke the SMMU aperture setup firmware function,
which is required to allow the GPU to manage per-process page tables in
some firmware versions - as an example Rb3Gen2 has no GPU without this.

Add X1E Devkit to the list of devices that has functional EFI variable
access through the uefisecapp.

Flip the "manual slice configuration quirk" in the Qualcomm LLCC driver,
as this only applies to a single platform, and introduce support for
QCS8300, QCS615, SAR2130P, and SAR1130P.

Lastly, add IPQ5424 and IPQ5404 to the Qualcomm socinfo driver.

98e5b7f983 drm/msm/adreno: Setup SMMU aparture for per-process page table
Support for per-process page tables requires the SMMU aparture to be
setup such that the GPU can make updates with the SMMU. On some targets
this is done statically in firmware, on others it's expected to be
requested in runtime by the driver, through a SCM call.

One place where configuration is expected to be done dynamically is the
QCS6490 rb3gen2.

The downstream driver does this unconditioanlly on any A6xx and newer,
so follow suite and make the call.

d6d1ad32d0 drm/msm/a6xx: Fix excessive stack usage
Clang-19 and above sometimes end up with multiple copies of the large
a6xx_hfi_msg_bw_table structure on the stack. The problem is that
a6xx_hfi_send_bw_table() calls a number of device specific functions to
fill the structure, but these create another copy of the structure on
the stack which gets copied to the first.

If the functions get inlined, that busts the warning limit:

drivers/gpu/drm/msm/adreno/a6xx_hfi.c:631:12: error: stack frame size (1032) exceeds limit (1024) in 'a6xx_hfi_send_bw_table' [-Werror,-Wframe-larger-than]

Fix this by kmalloc-ating struct a6xx_hfi_msg_bw_table instead of using
the stack. Also, use this opportunity to skip re-initializing this table
to optimize gpu wake up latency.

77ad507dbb drm/msm/a6xx+: Insert a fence wait before SMMU table update
The CP_SMMU_TABLE_UPDATE _should_ be waiting for idle, but on some
devices (x1-85, possibly others), it seems to pass that barrier while
there are still things in the event completion FIFO waiting to be
written back to memory.

Work around that by adding a fence wait before context switch.  The
CP_EVENT_WRITE that writes the fence is the last write from a submit,
so seeing this value hit memory is a reliable indication that it is
safe to proceed with the context switch.

v2: Only emit CP_WAIT_TIMESTAMP on a7xx, as it is not supported on a6xx.
    Conversely, I've not been able to reproduce this issue on a6xx, so
    hopefully it is limited to a7xx, or perhaps just certain a7xx
    devices.

When this flag is not set preemption will not be allowed in the middle

The flag is rejected if preemption is not supported on the target, this
allows userspace to know whether preemption is supported.

This patch implements preemption feature for A6xx targets, this allows
the GPU to switch to a higher priority ringbuffer if one is ready. A6XX
hardware as such supports multiple levels of preemption granularities,
ranging from coarse grained(ringbuffer level) to a more fine grained
such as draw-call level or a bin boundary level preemption. This patch
enables the basic preemption level, with more fine grained preemption
support to follow.
