In a rare situation of thermal limit during resume, GuC can
be slow and run into delays like this:
xe 0000:00:02.0: [drm] GT1: excessive init time: 667ms! \
[status = 0x8002F034, timeouts = 0]
xe 0000:00:02.0: [drm] GT1: excessive init time: \
[freq = 100MHz (req = 800MHz), before = 100MHz, \
perf_limit_reasons = 0x1C001000]
xe 0000:00:02.0: [drm] *ERROR* GT1: GuC PC Start failed
------------[ cut here ]------------
xe 0000:00:02.0: [drm] GT1: Failed to start GuC PC: -EIO
When this happens, it will block entirely the GPU to be used.
So, let's try and with a huge timeout in the hope it comes back.
Also, let's collect some information on how long it is usually
taking on situations like this, so perhaps the time can be tuned
later.

Currently, many instability cases related to D3Cold -> D0 transition
on BMG are under investigation. Among them some bad cases where
the device is lost after 1 to 3 transitions from D3Cold to D0
on the runtime pm, with pcieport upstream bridge port link retrain
failure.
In other cases, it works fine, but with some sudden random memory
corruptions after D3cold, that could be 0xffff missed ack on GT
forcewake or GuC reload related failures.
In some other cases though, D3Cold -> D0 works pretty reliably.
It looks like it is a combination of GPU cards and Host boards at
this point. So, there is no possible/available quirk at this time.
This patch disables the D3Cold by default on BMG by reducing the
vram_d3cold_threshold to 0. Users and developers who wants to enable
it are still able to via
$ echo 300 > /sys/bus/pci/devices/<addr>/vram_d3cold_threshold

We currently call intel_set_cdclk_post_plane_update() far
too early. When pipes are active during the reprogramming
the current spot only works for the cd2x divider update
case, as that is synchronize to the pipe's vblank. Squashing
and crawling are not synchronized in any way, so doing the
programming while the pipes/planes are potentially still using
the old hardware state could lead to underruns.
Move the post plane reprgramming to a spot where we know
that the pipes/planes have switched over the new hardware
state.

Some register groups reserve a byte at the end of their continuous
address space. Depending on the variant of silicon, this field may
share the same memory space as the lower byte of the system status
register (0x10).
In these cases, caching the reserved byte and writing it later may
effectively reset the device depending on what happened in between
the read and write operations.
Solve this problem by avoiding any access to this last byte within
offending register groups. This method replaces a workaround which
attempted to write the reserved byte with up-to-date contents, but
left a small window in which updates by the device could have been
clobbered.
Now that the driver does not touch these reserved bytes, the order
in which the device's registers are written no longer matters, and
they can be written in their natural order. The new method is also
much more generic, and can be more easily extended to new variants
of silicon with different register maps.
As part of this change, the register read and write functions must
be gently updated to support byte access instead of word access.

Gen 2 Hyper-V VMs boot via EFI and have a standard EFI framebuffer
device. When the kdump kernel runs in such a VM, loading the efifb
driver may hang because of accessing the framebuffer at the wrong
memory address.
The scenario occurs when the hyperv_fb driver in the original kernel
moves the framebuffer to a different MMIO address because of conflicts
with an already-running efifb or simplefb driver. The hyperv_fb driver
then informs Hyper-V of the change, which is allowed by the Hyper-V FB
VMBus device protocol. However, when the kexec command loads the kdump
kernel into crash memory via the kexec_file_load() system call, the
system call doesn't know the framebuffer has moved, and it sets up the
kdump screen_info using the original framebuffer address. The transition
to the kdump kernel does not go through the Hyper-V host, so Hyper-V
does not reset the framebuffer address like it would do on a reboot.
When efifb tries to run, it accesses a non-existent framebuffer
address, which traps to the Hyper-V host. After many such accesses,
the Hyper-V host thinks the guest is being malicious, and throttles
the guest to the point that it runs very slowly or appears to have hung.
When the kdump kernel is loaded into crash memory via the kexec_load()
system call, the problem does not occur. In this case, the kexec command
builds the screen_info table itself in user space from data returned
by the FBIOGET_FSCREENINFO ioctl against /dev/fb0, which gives it the
new framebuffer location.
This problem was originally reported in 2020 [1], resulting in commit
3cb73bc3fa2a ("hyperv_fb: Update screen_info after removing old
framebuffer"). This commit solved the problem by setting orig_video_isVGA
to 0, so the kdump kernel was unaware of the EFI framebuffer. The efifb
driver did not try to load, and no hang occurred. But in 2024, commit
c25a19afb81c ("fbdev/hyperv_fb: Do not clear global screen_info")
effectively reverted 3cb73bc3fa2a. Commit c25a19afb81c has no reference
to 3cb73bc3fa2a, so perhaps it was done without knowing the implications
that were reported with 3cb73bc3fa2a. In any case, as of commit
c25a19afb81c, the original problem came back again.
Interestingly, the hyperv_drm driver does not have this problem because
it never moves the framebuffer. The difference is that the hyperv_drm
driver removes any conflicting framebuffers *before* allocating an MMIO
address, while the hyperv_fb drivers removes conflicting framebuffers
*after* allocating an MMIO address. With the "after" ordering, hyperv_fb
may encounter a conflict and move the framebuffer to a different MMIO
address. But the conflict is essentially bogus because it is removed
a few lines of code later.
Rather than fix the problem with the approach from 2020 in commit
3cb73bc3fa2a, instead slightly reorder the steps in hyperv_fb so
conflicting framebuffers are removed before allocating an MMIO address.
Then the default framebuffer MMIO address should always be available, and
there's never any confusion about which framebuffer address the kdump
kernel should use -- it's always the original address provided by
the Hyper-V host. This approach is already used by the hyperv_drm
driver, and is consistent with the usage guidelines at the head of
the module with the function aperture_remove_conflicting_devices().
This approach also solves a related minor problem when kexec_load()
is used to load the kdump kernel. With current code, unbinding and
rebinding the hyperv_fb driver could result in the framebuffer moving
back to the default framebuffer address, because on the rebind there
are no conflicts. If such a move is done after the kdump kernel is
loaded with the new framebuffer address, at kdump time it could again
have the wrong address.
This problem and fix are described in terms of the kdump kernel, but
it can also occur with any kernel started via kexec.
See extensive discussion of the problem and solution at [2].

When a Hyper-V DRM device is probed, the driver allocates MMIO space for
the vram, and maps it cacheable. If the device removed, or in the error
path for device probing, the MMIO space is released but no unmap is done.
Consequently the kernel address space for the mapping is leaked.
Fix this by adding iounmap() calls in the device removal path, and in the
error path during device probing.

ATU Load operations could fail silently if there's not enough space
on the device to hold the new entry. When this happens, the symptom
depends on the unknown flood settings. If unknown multicast flood is
disabled, the multicast packets are dropped when the ATU table is
full. If unknown multicast flood is enabled, the multicast packets
will be flooded to all ports. Either way, IGMP snooping is broken
when the ATU Load operation fails silently.
Do a Read-After-Write verification after each fdb/mdb add operation
to make sure that the operation was really successful, and return
-ENOSPC otherwise.

Automatically configure the altsetting for HCI_USER_CHANNEL when a SCO
is connected.
The motivation is to enable the HCI_USER_CHANNEL user to send out SCO
data through USB Bluetooth chips, which is mainly used for bidirectional
audio transfer (voice call). This was not capable because:
- Per Bluetooth Core Spec v5, Vol 4, Part B, 2.1, the corresponding
alternate setting should be set based on the air mode in order to
transfer SCO data, but
- The Linux Bluetooth HCI_USER_CHANNEL exposes the Bluetooth Host
Controller Interface to the user space, which is something above the
USB layer. The user space is not able to configure the USB alt while
keeping the channel open.
This patch intercepts the HCI_EV_SYNC_CONN_COMPLETE packets in btusb,
extracts the air mode, and configures the alt setting in btusb.
This patch is tested on ChromeOS devices. The USB Bluetooth models
(CVSD, TRANS alt3 and alt6) could work without a customized kernel.

Compared to the SNP Guest Request, the "Extended" version adds data pages for
receiving certificates. If not enough pages provided, the HV can report to the
VM how much is needed so the VM can reallocate and repeat.
Commit
ae596615d93d ("virt: sev-guest: Reduce the scope of SNP command mutex")
moved handling of the allocated/desired pages number out of scope of said
mutex and create a possibility for a race (multiple instances trying to
trigger Extended request in a VM) as there is just one instance of
snp_msg_desc per /dev/sev-guest and no locking other than snp_cmd_mutex.
Fix the issue by moving the data blob/size and the GHCB input struct
(snp_req_data) into snp_guest_req which is allocated on stack now and accessed
by the GHCB caller under that mutex.
Stop allocating SEV_FW_BLOB_MAX_SIZE in snp_msg_alloc() as only one of four
callers needs it. Free the received blob in get_ext_report() right after it is
copied to the userspace. Possible future users of snp_send_guest_request() are
likely to have different ideas about the buffer size anyways.

Commit
ae596615d93d ("virt: sev-guest: Reduce the scope of SNP command mutex")
narrowed the command mutex scope to snp_send_guest_request(). However,
GET_REPORT, GET_DERIVED_KEY, and GET_EXT_REPORT share the req structure in
snp_guest_dev. Without the mutex protection, concurrent requests can overwrite
each other's data. Fix it by dynamically allocating the request structure.

Kenneth noticed that his laptop crashes randomly when resuming from
hibernate if there is device connected and display tunneled. I was able
to reproduce this as well with the following steps:
1. Boot the system up, nothing connected.
2. Connect Thunderbolt 4 dock to the host.
3. Connect monitor to the Thunderbolt 4 dock.
4. Verify that there is picture on the screen.
5. Enter hibernate.
6. Exit hibernate.
7. Wait for the system to resume.
Expectation: System resumes just fine, the connected monitor still
shows screen.
Actual result: There is crash during resume, screen is blank.
What happens is that during resume from hibernate we tear down any
existing tunnels created by the boot kernel and this ends up calling
tb_dp_dprx_stop() which calls tb_tunnel_put() dropping the reference
count to zero even though we never called tb_dp_dprx_start() for it (we
never do that for discovery). This makes the discovered DP tunnel memory
to be released and any access after that causes use-after-free and
possible crash.
Fix this so that we only stop DPRX flow if it has been started in the
first place.

If the restart work happens to run after the opmode left
(i.e. called iwl_trans_op_mode_leave), then the opmode memory (including
its mutex) is likely to be freed already, and trans->opmode is NULL.
Although the hw is stopped in that stage, which means that this restart
got aborted (i.e. STATUS_RESET_PENDING will be cleared),
it still can access trans->opmode (NULL pointer dereference)
or the opmodes memory (which is freed).
Fix this by canceling the restart wk in iwl_trans_op_mode_leave.
Also make sure that the restart wk is really aborted.

When MSI-X is not enabled, we mask all the interrupts in the interrupt
handler and re-enable them when the interrupt thread runs. If
STATUS_INT_ENABLED is not set, we won't re-enable in the thread.
In order to get the ALIVE interrupt, we allow the ALIVE interrupt
itself, and RX as well in order to receive the ALIVE notification (which
is received as an RX from the firmware.
The problem is that STATUS_INT_ENABLED is clear until the op_mode calls
trans_fw_alive which means that until trans_fw_alive is called, any
notification from the firmware will not be received.
This became a problem when we inserted the pnvm_load exactly between the
ALIVE and trans_fw_alive.
Fix that by calling trans_fw_alive before loading the PNVM. This will
allow to get the notification from the firmware about PNVM load being
complete and continue the flow normally.
This didn't happen on MSI-X because we don't disable the interrupts in
the ISR when MSI-X is available.
The error in the log looks like this:
iwlwifi 0000:00:03.0: Timeout waiting for PNVM load!
iwlwifi 0000:00:03.0: Failed to start RT ucode: -110

The fix to atomically read the pipe head and tail state when not holding
the pipe mutex has caused a number of headaches due to the size change
of the involved types.
It turns out that we don't have _that_ many places that access these
fields directly and were affected, but we have more than we strictly
should have, because our low-level helper functions have been designed
to have intimate knowledge of how the pipes work.
And as a result, that random noise of direct 'pipe->head' and
'pipe->tail' accesses makes it harder to pinpoint any actual potential
problem spots remaining.
For example, we didn't have a "is the pipe full" helper function, but
instead had a "given these pipe buffer indexes and this pipe size, is
the pipe full". That's because some low-level pipe code does actually
want that much more complicated interface.
But most other places literally just want a "is the pipe full" helper,
and not having it meant that those places ended up being unnecessarily
much too aware of this all.
It would have been much better if only the very core pipe code that
cared had been the one aware of this all.
So let's fix it - better late than never. This just introduces the
trivial wrappers for "is this pipe full or empty" and to get how many
pipe buffers are used, so that instead of writing
if (pipe_full(pipe->head, pipe->tail, pipe->max_usage))
the places that literally just want to know if a pipe is full can just
say
if (pipe_is_full(pipe))
instead. The existing trivial cases were converted with a 'sed' script.
This cuts down on the places that access pipe->head and pipe->tail
directly outside of the pipe code (and core splice code) quite a lot.
The splice code in particular still revels in doing the direct low-level
accesses, and the fuse fuse_dev_splice_write() code also seems a bit
unnecessarily eager to go very low-level, but it's at least a bit better
than it used to be.

When used on Huawei hisi platforms, Prolific Mass Storage Card Reader
which the VID:PID is in 067b:2731 might fail to enumerate at boot time
and doesn't work well with LPM enabled, combination quirks:
USB_QUIRK_DELAY_INIT + USB_QUIRK_NO_LPM
fixed the problems.

of_parse_phandle_with_fixed_args() requires its caller to
call into of_node_put() on the node pointer from the output
structure, but such a call is currently missing.
Call into of_node_put() to rectify that.

Since pci_get_domain_bus_and_slot() can return NULL, add NULL check for
pci_gfx_root in the mid_get_vbt_data().
This change is similar to the checks implemented in mid_get_fuse_settings()
and mid_get_pci_revID(), which were introduced by commit 0cecdd818cd7
("gma500: Final enables for Oaktrail") as "additional minor
bulletproofing".
Found by Linux Verification Center (linuxtesting.org) with SVACE.
