Currently, a limit of 0 results in a hard coded metering over 6 hours.
Since the default is a set limit, I suspect no one truly depends on this
rather arbitrary setting. Repurpose it for an arguably more useful
"unlimited" mode, where the delay is 0.
Note that if block groups are too new, or go fully empty, there is still
a delay associated with those conditions. Those delays implement
heuristics for not trimming a region we are relatively likely to fully
overwrite soon.

Previously, the default was a relatively conservative 10. This results
in a 100ms delay, so with ~300 discards in a commit, it takes the full
30s till the next commit to finish the discards. On a workstation, this
results in the disk never going idle, wasting power/battery, etc.
Set the default to 1000, which results in using the smallest possible
delay, currently, which is 1ms. This has shown to not pathologically
keep the disk busy by the original reporter.

blk-mq sched bio merge still needs request to grab queue usage counter,
so we can't simply call blk_mq_attempt_bio_merge() when queue usage
counter isn't held.

The current code path can lead to warnings because of uninitialized device,
which contains, as a consequence, uninitialized kobject. The uninitialized
device is passed to of_platform_populate, which will at some point, while
creating child device, try to get a reference on uninitialized parent,
resulting in the following warning:
kobject: '(null)' ((ptrval)): is not initialized, yet kobject_get() is
being called.
The warning is observed after migrating a kernel 5.10.x to 6.1.x.
Reverting commit 0d70af3c2530 ("fpga: bridge: Use standard dev_release for
class driver") seems to remove the warning.
This commit aggregates device_initialize() and device_add() into
device_register() but this new call is done AFTER of_platform_populate

Driver has IO wrappers but xlnx_pr_decouple_read() is not used and readl is
used instead which is just wrong.
It is also generating sparse issue that xlnx_pr_decouple_read() is unused.

pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages. Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration, so the
driver doesn't need to do it itself.
Remove the redundant pci_enable_pcie_error_reporting() call from the
driver. Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.
Note that this only controls ERR_* Messages from the device. An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

dma_request_slave_channel() may return NULL which will lead to
NULL pointer dereference error in 'tmp_chan->private'.
Correct this behaviour by, first, switching from deprecated function
dma_request_slave_channel() to dma_request_chan(). Secondly, enable
sanity check for the resuling value of dma_request_chan().
Also, fix description that follows the enacted changes and that
concerns the use of dma_request_slave_channel().

With PCI if the device was suspended it is brought back to full
power and then suspended again.
This doesn't happen when device is described via DT.
We need to make sure that we tear down pipelines only if the device
was previously active (thus the pipelines were setup).
Otherwise, we can break the use_count:
[ 219.009743] sof-audio-of-imx8m 3b6e8000.dsp:
sof_ipc3_tear_down_all_pipelines: widget PIPELINE.2.SAI3.IN is still in use: count -1
and after this everything stops working.

The original patch uses a feature in lib/vsprintf.c to handle the invalid
address when tring to print *_fw_module->man4_module_entry.name when the
*rc_fw_module is NULL.
This case is handled by check_pointer_msg() internally and turns the
invalid pointer to '(efault)' for printing but it is hiding useful
information about the circumstances. Change the print to emmit the name
of the widget and a note on which side's fw_module is missing.

Unfortunately, the tester gave a weak feedback (working/non-working) for
this case. After the double confirmation, this change is not really required.
The standard code with alc269_fallback_pin_fixup_tbl should work on this

1. It could hit bandwidth limitdation under single dimm
memory when connecting 8K external monitor.
2. IsSupportedVidPn got validation failed with
2K240Hz eDP + 8K24Hz external monitor.
3. It's better to filter out such combination in
EnumVidPnCofuncModality
4. For short term, filter out in dc bandwidth validation.
[How]
Force 2K@240Hz+8K@24Hz timing validation false in dc.

| | | | | | | | | | | | | | | |
[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.

Fast wake should use 8 SYNC pulses for the preamble
and 10-16 SYNC pulses for the precharge. Reduce our
fast wake SYNC count to match the maximum value.
We also use the maximum precharge length for normal
AUX transactions.

afa965a45e01 ("drm/rockchip: vop2: fix suspend/resume") uses
regmap_reinit_cache() to fix the suspend/resume issue with the VOP2
driver. During discussion it came up that we should rather use
regcache_sync() instead. As the original patch is already applied
fix this up in this follow-up patch.

Commit 41d351f29528 ("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
success as opposed to ttm_bo_wait_ctx(). As a result, relocs
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.

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.

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.

Pull pci fix from Bjorn Helgaas:
- Previously we ignored PCI devices if the DT "status" property or the
ACPI _STA method said it was not present.
Per spec, _STA cannot be used for that purpose, and using it that way
caused regressions, so skip the _STA check (Rob Herring)

Commit 6fffbc7ae137 ("PCI: Honor firmware's device disabled status")
checked the firmware device status for both DT and ACPI devices. That
caused a regression in some ACPI systems. The exact reason isn't clear.
It's possibly a firmware bug. For now, at least, refactor the check to
be for DT based systems only.
Note that the original implementation leaked a refcount which is now
correctly handled.

must return with bit[0] ("device is present") set]

ath9k_mci_update_wlan_channels()
This partially reverts commit e161d4b60ae3a5356e07202e0bfedb5fad82c6aa.
Turns out the channelmap variable is not actually read-only, it's modified
through the MCI_GPM_CLR_CHANNEL_BIT() macro further down in the function,
so making it read-only causes page faults when that code is hit.

With CONFIG_INIT_STACK_ALL_ZERO enabled, bindgen passes
-ftrivial-auto-var-init=zero to clang, that triggers the following
error:
error: '-ftrivial-auto-var-init=zero' hasn't been enabled; enable it at your own peril for benchmarking purpose only with '-enable-trivial-auto-var-init-zero-knowing-it-will-be-removed-from-clang'
However, this additional option that is currently required by clang is
deprecated since clang-16 and going to be removed in the future,
likely with clang-18.
So, make sure bindgen is using this extra option if the major version of
the libclang used by bindgen is < 16.
In this way we can enable CONFIG_INIT_STACK_ALL_ZERO with CONFIG_RUST
without triggering any build error.

nm can use "R" or "r" to show read-only data sections, but
scripts/is_rust_module.sh can only recognize "r", so with some versions
of binutils it can fail to detect if a module is a Rust module or not.
Right now we're using this script only to determine if we need to skip
BTF generation (that is disabled globally if CONFIG_RUST is enabled),
but it's still nice to fix this script to do the proper job.
Moreover, with this patch applied I can also relax the constraint of
"RUST depends on !DEBUG_INFO_BTF" and build a kernel with Rust and BTF
enabled at the same time (of course BTF generation is still skipped for
Rust modules).
[ Miguel: The actual reason is likely to be a change on the Rust
compiler between 1.61.0 and 1.62.0:
echo '#[used] static S: () = ();' |
rustup run 1.61.0 rustc --emit=obj --crate-type=lib - &&
nm rust_out.o
echo '#[used] static S: () = ();' |
rustup run 1.62.0 rustc --emit=obj --crate-type=lib - &&
nm rust_out.o
