Commands like Write Zeros can change the contents of a namespaces without
actually transferring data. To protect against this, check the Commands
Supported and Effects log is supported by the controller for any
unprivileg command passthrough and refuse unprivileged passthrough if the
command has any effects that can change data or metadata.
Note: While the Commands Support and Effects log page has only been
mandatory since NVMe 2.0, it is widely supported because Windows requires
it for any command passthrough from userspace.

To be able to use the Commands Supported and Effects Log for allowing
unprivileged passtrough, it needs to be corretly reported for I/O
commands as well. Return the I/O command effects from
nvme_command_effects, and also add a default list of effects for the
NVM command set. For other command sets, the Commands Supported and
Effects log is required to be present already.

Mask out the "Command Supported" and "Logical Block Content Change" bits
and only defer execution of commands that have non-trivial effects to
the workqueue for synchronous execution. This allows to execute admin
commands asynchronously on controllers that provide a Command Supported
and Effects log page, and will keep allowing to execute Write commands
asynchronously once command effects on I/O commands are taken into
account.

While the CAP.MQES field in NVMe is a 0s based filed with a natural one
off, we also need to account for the queue wrap condition and fix undo
the one off again in nvme_alloc_io_tag_set. This was never properly
done by the fabrics drivers, but they don't seem to care because there
is no actual physical queue that can wrap around, but it became a
problem when converting over the PCIe driver. Also add back the
BLK_MQ_MAX_DEPTH check that was lost in the same commit.

Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown". After a timer is set to this state, then it can no
longer be re-armed.
The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed. It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.
This was created by using a coccinelle script and the following
commands:
$ cat timer.cocci
@@
expression ptr, slab;
identifier timer, rfield;
@@
(
- del_timer(&ptr->timer);
+ timer_shutdown(&ptr->timer);

- del_timer_sync(&ptr->timer);

After we introduced a module parameter and quirk infrastructure for
picking the Microsoft GUID over the SOC vendor GUID we discovered
that lots and lots of systems are getting this wrong.
The table continues to grow, and is becoming unwieldy.
We don't really have any benefit to forcing vendors to populate the
AMD GUID. This is just extra work, and more and more vendors seem
to mess it up. As the Microsoft GUID is used by Windows as well,
it's very likely that it won't be messed up like this.
So drop all the quirks forcing it and the Rembrandt behavior. This
means that Cezanne or later effectively only run the Microsoft GUID
codepath with the exception of HP Elitebook 8*5 G9.

HP Elitebook 865 supports both the AMD GUID w/ _REV 2 and Microsoft
GUID with _REV 0. Both have very similar code but the AMD GUID
has a special workaround that is specific to a problem with
spurious wakeups on systems with Qualcomm WLAN.
This is believed to be a bug in the Qualcomm WLAN F/W (it doesn't
affect any other WLAN H/W). If this WLAN firmware is fixed this
quirk can be dropped.

The apple-gmux driver only binds to old GMUX devices which have an
IORESOURCE_IO resource (using inb()/outb()) rather then memory-mapped
IO (IORESOURCE_MEM).
T2 MacBooks use the new style GMUX devices (with IORESOURCE_MEM access),
so these are not supported by the apple-gmux driver. This is not a problem
since they have working ACPI video backlight support.
But the apple_gmux_present() helper only checks if an ACPI device with
the "APP000B" HID is present, causing acpi_video_get_backlight_type()
to return acpi_backlight_apple_gmux disabling the acpi_video backlight
device.
Add a new apple_gmux_backlight_present() helper which checks that
the "APP000B" device actually is an old GMUX device with an IORESOURCE_IO
resource.
This fixes the acpi_video0 backlight no longer registering on T2 MacBooks.
Note people are working to add support for the new style GMUX to Linux:
https://github.com/kekrby/linux-t2/commits/wip/hybrid-graphics
Once this lands this patch should be reverted so that
acpi_video_get_backlight_type() also prefers the gmux on new style GMUX
MacBooks, but for now this is necessary to avoid regressing backlight
control on T2 Macs.

The ACPI video detection code has a module parameter
`register_backlight_delay` which is currently configured to 8 seconds.
This means that if after 8 seconds of booting no native driver has created
a backlight device then the code will attempt to make an ACPI video
backlight device.
This was intended as a safety mechanism with the backlight overhaul that
occurred in kernel 6.1, but as it doesn't appear necesssary set it to be
disabled by default.

On desktop APUs amdgpu doesn't create a native backlight device
as no eDP panels are found. However if the BIOS has reported
backlight control methods in the ACPI tables then an acpi_video0
backlight device will be made 8 seconds after boot.
This has manifested in a power slider on a number of desktop APUs
ranging from Ryzen 5000 through Ryzen 7000 on various motherboard
manufacturers. To avoid this, report to the acpi video detection
that the system does not have any panel connected in the native

8 seconds after the system has booted if the ACPI tables
included backlight control methods.
If the GPU drivers have loaded, they may be able to report whether
any LCD panels were found. Allow using this information to factor
in whether to enable the fallback logic for making an acpi_video0

Pull more random number generator updates from Jason Donenfeld:
"Two remaining changes that are now possible after you merged a few
other trees:
- #include <asm/archrandom.h> can be removed from random.h now,
making the direct use of the arch_random_* API more of a private
implementation detail between the archs and random.c, rather than
something for general consumers.
- Two additional uses of prandom_u32_max() snuck in during the
initial phase of pulls, so these have been converted to
get_random_u32_below(), and now the deprecated prandom_u32_max()
alias -- which was just a wrapper around get_random_u32_below() --
can be removed.
In addition, there is one fix:
- Check efi_rt_services_supported() before attempting to use an EFI
runtime function.
This affected EFI systems that disable runtime services yet still
boot via EFI (e.g. the reporter's Lenovo Thinkpad X13s laptop), as
well systems where EFI runtime services have been forcibly
disabled, such as on PREEMPT_RT.
On those machines, a very early and hard to diagnose crash would
happen, preventing boot"

Convert the max size to bytes to match the units of the divisor that
calculates the worst-case number of PRP entries.
The result is used to determine how many PRP Lists are required. The
code was previously rounding this to 1 list, but we can require 2 in the
worst case. In that scenario, the driver would corrupt memory beyond the
size provided by the mempool.
While unlikely to occur (you'd need a 4MB in exactly 127 phys segments
on a queue that doesn't support SGLs), this memory corruption has been
observed by kfence.

When using shadow doorbells, the event index and the doorbell values are
written to host memory. Prior to this patch, the values written would
erroneously be written in host endianness. This causes trouble on
big-endian platforms. Fix this by adding missing endian conversions.
This issue was noticed by Guenter while testing various big-endian
platforms under QEMU[1]. A similar fix required for hw/nvme in QEMU is
up for review as well[2].

The build_skb might return a null pointer but there is no check on the
return value in the fec_enet_rx_queue(). So a null pointer dereference
might occur. To avoid this, we check the return value of build_skb. If
the return value is a null pointer, the driver will recycle the page and
update the statistic of ndev. Then jump to rx_processing_done to clear
the status flags of the BD so that the hardware can recycle the BD.

MES is part of gfxoff and MES suspend and resume are skipped for S0i3.
But the mes_self_test call path is still in the amdgpu_device_ip_late_init.
it's should also be skipped for s0ix as no hardware re-initialization
happened.
Besides, mes_self_test will free the BO that triggers a lot of warning
messages while in the suspend state.

For SMU 13.0.0 and 13.0.7, the output from PMFW is in percent. Driver
need to convert that into correct PMW(255) based.

The activity_monitor_external[] array is too big to fit on the
kernel stack, resulting in this warning with clang:
drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu13/smu_v13_0_7_ppt.c:1438:12: error: stack frame size (1040) exceeds limit (1024) in 'smu_v13_0_7_get_power_profile_mode' [-Werror,-Wframe-larger-than]
Use dynamic allocation instead. It should also be possible to
have single element here instead of the array, but this seems
easier.
v2: fix up argument to sizeof() (Alex)

If kfd_process_device_init_vm returns failure after vm is converted to
compute vm and vm->pasid set to compute pasid, KFD will not take
pdd->drm_file reference. As a result, drm close file handler maybe
called to release the compute pasid before KFD process destroy worker to
release the same pasid and set vm->pasid to zero, this generates below
WARNING backtrace and NULL pointer access.
Add helper amdgpu_amdkfd_gpuvm_set_vm_pasid and call it at the last step
of kfd_process_device_init_vm, to ensure vm pasid is the original pasid
if acquiring vm failed or is the compute pasid with pdd->drm_file
reference taken to avoid double release same pasid.
