Actually, the drm_dev_enter in psp_cmd_submit_buf does not
protect anything. If DRM device is unplugged, it will always
check the condition in WARN_ON. So drop drm_dev_enter and
drm_dev_exit in psp_cmd_submit_buf.
When removing amdgpu, the calling order is as follows:
amdgpu_pci_remove
drm_dev_unplug
amdgpu_driver_unload_kms
amdgpu_device_fini_hw

The same strapping initialization issue that happened on NBIO 7.5.1
appears to be happening on NBIO 7.3.0.
Apply the same fix to 7.3.0 as well.
Note: This workaround relies upon the integrated GPU being enabled
in BIOS. If the integrated GPU is disabled in BIOS a different
workaround will be required.

msm-fixes for v6.3-rc2
- Fix for possible invalid ptr free in submit ioctl syncobj cleanup path.
- Synchronize GMU removal in driver teardown path
- a5xx preemption fixes
- Fix runpm imbalance at unbind
- DPU hw catalog fixes:
- set DPU_MDP_PERIPH_0_REMOVED for sc8280xp as this is another chipset
where the PERIPH_0 block of registers is not there
- fix the DPU features supported in QCM2290 by comparing it with the
downstream device tree
- fix the length of registers in the sc7180_ctl from 0xe4 to 0x1dc
- fix the max mixer line width for sm6115 and qcm2290 chipsets in the
DPU catalog
- fix the scaler version on sm8550, sc8280xp, sm8450, sm8250, sm8350
and sm6115. This was incorrectly populated on the SW version of the
scaler library and not the scaler HW version
- Drop dim layer support for msm8998 as its not indicated to be
supported in the downstream DTSI
- fix the DPU_CLK_CTRL bits for msm 8998 sspp blocks
- Use DPU_CLK_CTRL_DMA* prefix instead of DPU_CLK_CTRL_CURSOR*
for all chipsets for the DMA sspp blocks
- fix the ping-pong block base address for sc7280 in the DPU HW catalog
- Fix stack corruption issue in the dpu_hw_ctl_setup_blendstage() function
as it was causing a negative left shift by protecting against an invalid
index
- Clear the DSPP reservations in dpu_rm_release(). This was missed out and
as as result the DSPP was not released from the resource manager global
state.

The MT7530 switch from the MT7621 SoC has 2 ports which can be set up as
internal: port 5 and 6. Arınç reports that the GMAC1 attached to port 5
receives corrupted frames, unless port 6 (attached to GMAC0) has been
brought up by the driver. This is true regardless of whether port 5 is
used as a user port or as a CPU port (carrying DSA tags).
Offline debugging (blind for me) which began in the linked thread showed
experimentally that the configuration done by the driver for port 6
contains a step which is needed by port 5 as well - the write to
CORE_GSWPLL_GRP2 (note that I've no idea as to what it does, apart from
the comment "Set core clock into 500Mhz"). Prints put by Arınç show that
the reset value of CORE_GSWPLL_GRP2 is RG_GSWPLL_POSDIV_500M(1) |
RG_GSWPLL_FBKDIV_500M(40) (0x128), both on the MCM MT7530 from the
MT7621 SoC, as well as on the standalone MT7530 from MT7623NI Bananapi
BPI-R2. Apparently, port 5 on the standalone MT7530 can work under both
values of the register, while on the MT7621 SoC it cannot.
The call path that triggers the register write is:
mt753x_phylink_mac_config() for port 6
-> mt753x_pad_setup()
-> mt7530_pad_clk_setup()
so this fully explains the behavior noticed by Arınç, that bringing port
6 up is necessary.
The simplest fix for the problem is to extract the register writes which
are needed for both port 5 and 6 into a common mt7530_pll_setup()
function, which is called at mt7530_setup() time, immediately after
switch reset. We can argue that this mirrors the code layout introduced
in mt7531_setup() by commit 42bc4fafe359 ("net: mt7531: only do PLL once
after the reset"), in that the PLL setup has the exact same positioning,
and further work to consolidate the separate setup() functions is not
hindered.
Testing confirms that:
- the slight reordering of writes to MT7530_P6ECR and to
CORE_GSWPLL_GRP1 / CORE_GSWPLL_GRP2 introduced by this change does not
appear to cause problems for the operation of port 6 on MT7621 and on
MT7623 (where port 5 also always worked)
- packets sent through port 5 are not corrupted anymore, regardless of
whether port 6 is enabled by phylink or not (or even present in the
device tree)
My algorithm for determining the Fixes: tag is as follows. Testing shows
that some logic from mt7530_pad_clk_setup() is needed even for port 5.
Prior to commit ca366d6c889b ("net: dsa: mt7530: Convert to PHYLINK
API"), a call did exist for all phy_is_pseudo_fixed_link() ports - so
port 5 included. That commit replaced it with a temporary "Port 5 is not
supported!" comment, and the following commit 38f790a80560 ("net: dsa:
mt7530: Add support for port 5") replaced that comment with a
configuration procedure in mt7530_setup_port5() which was insufficient
for port 5 to work. I'm laying the blame on the patch that claimed
support for port 5, although one would have also needed the change from
commit c3b8e07909db ("net: dsa: mt7530: setup core clock even in TRGMII
mode") for the write to be performed completely independently from port
6's configuration.
Thanks go to Arınç for describing the problem, for debugging and for
testing.

Fix deletion of existing DSCP mappings in the APP table.
Adding and deleting DSCP entries are replicated per-port, since the
mapping table is global for all ports in the chip. Whenever a mapping
for a DSCP value already exists, the old mapping is deleted first.
However, it is only deleted for the specified port. Fix this by calling
sparx5_dcb_ieee_delapp() instead of dcb_ieee_delapp() as it ought to be.
Reproduce:
// Map and remap DSCP value 63
$ dcb app add dev eth0 dscp-prio 63:1
$ dcb app add dev eth0 dscp-prio 63:2
$ dcb app show dev eth0 dscp-prio
dscp-prio 63:2
$ dcb app show dev eth1 dscp-prio
dscp-prio 63:1 63:2 <-- 63:1 should not be there

PFCENABLE field was being masked with a 4 bit mask (0xF), but this is an 8

[Why]
Currently, the clk manager matches SocVoltage with voltage from
fused settings (dfPstate clock table). And then corresponding clocks
are selected.
However in certain situations, this leads to clk manager not
including at least one entry with highest supported clock setting.
[How]
Update the clk manager to include at least one entry with highest
supported clock setting.

The EDID of an HDR display defines EOTFs that are supported
by the display and can be set in the HDR metadata infoframe.
Userspace is expected to read the EDID and set an appropriate
HDR_OUTPUT_METADATA.
In drm_parse_hdr_metadata_block the kernel reads the supported
EOTFs from the EDID and stores them in the
drm_connector->hdr_sink_metadata. While doing so it also
filters the EOTFs to the EOTFs the kernel knows about.
When an HDR_OUTPUT_METADATA is set it then checks to
make sure the EOTF is a supported EOTF. In cases where
the kernel doesn't know about a new EOTF this check will
fail, even if the EDID advertises support.
Since it is expected that userspace reads the EDID to understand
what the display supports it doesn't make sense for DRM to block
an HDR_OUTPUT_METADATA if it contains an EOTF the kernel doesn't
understand.
This comes with the added benefit of future-proofing metadata
support. If the spec defines a new EOTF there is no need to
update DRM and an compositor can immediately make use of it.

Fix data corruption issue with SerDes connected PHYs operating at 1.25
Gbps speed where we could previously observe about 30% packet loss while
the bad packet counter was increasing.
As almost all boards with MediaTek MT7622 or MT7986 use either the MT7531
switch IC operating at 3.125Gbps SerDes rate or single-port PHYs using
rate-adaptation to 2500Base-X mode, this issue only got exposed now when
we started trying to use SFP modules operating with 1.25 Gbps with the
BananaPi R3 board.
The fix is to set bit 12 which disables the RX FIFO clear function when
setting up MAC MCR, MediaTek SDK did the same change stating:
"If without this patch, kernel might receive invalid packets that are
corrupted by GMAC."[1]

It turns out that commit 596ff4a09b89 ("cpumask: re-introduce
constant-sized cpumask optimizations") exposed a number of cases of
drivers not checking the result of "cpumask_next()" and friends
correctly.
The documented correct check for "no more cpus in the cpumask" is to
check for the result being equal or larger than the number of possible
CPU ids, exactly _because_ we've always done those constant-sized
cpumask scans using a widened type before. So the return value of a
cpumask scan should be checked with
if (cpu >= nr_cpu_ids)
...
because the cpumask scan did not necessarily stop exactly *at* that
maximum CPU id.
But a few cases ended up instead using checks like
if (cpu == nr_cpumask_bits)
...
which used that internal "widened" number of bits. And that used to
work pretty much by accident (ok, in this case "by accident" is simply
because it matched the historical internal implementation of the cpumask
scanning, so it was more of a "intentionally using implementation
details rather than an accident").
But the extended constant-sized optimizations then did that internal
implementation differently, and now that code that did things wrong but
matched the old implementation no longer worked at all.
Which then causes subsequent odd problems due to using what ends up
being an invalid CPU ID.
Most of these cases require either unusual hardware or special uses to
hit, but the random.c one triggers quite easily.
All you really need is to have a sufficiently small CONFIG_NR_CPUS value
for the bit scanning optimization to be triggered, but not enough CPUs
to then actually fill that widened cpumask. At that point, the cpumask
scanning will return the NR_CPUS constant, which is _not_ the same as
nr_cpumask_bits.
This just does the mindless fix with
sed -i 's/== nr_cpumask_bits/>= nr_cpu_ids/'
to fix the incorrect uses.
The ones in the SCSI lpfc driver in particular could probably be fixed
more cleanly by just removing that repeated pattern entirely, but I am
not emptionally invested enough in that driver to care.

Auxiliary device structures are freed in bnxt_aux_dev_release. So avoid
calling kfree from bnxt_remove_one.
Also, set bp->edev to NULL before freeing the auxilary private structure.

The driver needs to keep track of all the possible concurrent TPA (GRO/LRO)
completions on the aggregation ring. On P5 chips, the maximum number
of concurrent TPA is 256 and the amount of memory we allocate is order-5
on systems using 4K pages. Memory allocation failure has been reported:

Instead of allocating this big chunk of memory and dividing it up for the
concurrent TPA instances, allocate each small chunk separately for each
TPA instance. This will reduce it to order-0 allocations.

The locking in phy_probe() and phy_remove() does very little to prevent
any races with e.g. phy_attach_direct(), but instead causes lockdep ABBA

When MAC is not support PMT, driver will check PHY's WoL capability
and set device wakeup capability in stmmac_init_phy(). We can enable
the WoL through ethtool, the driver would enable the device wake up
flag. Now the device_may_wakeup() return true.
But if there is a way which enable the PHY's WoL capability derectly,
like in BIOS. The driver would not know the enable thing and would not
set the device wake up flag. The phy_suspend may failed like this:
[ 32.409063] PM: dpm_run_callback(): mdio_bus_phy_suspend+0x0/0x50 returns -16
[ 32.409065] PM: Device stmmac-1:00 failed to suspend: error -16
[ 32.409067] PM: Some devices failed to suspend, or early wake event detected
Add to set the device wakeup enable flag according to the get_wol
function result in PHY can fix the error in this scene.
v2: add a Fixes tag.
