fq_dequeue() has a complex logic to find packets in one of the 3 bands.
As Neal found out, it is possible that one band has a deficit smaller
than its weight. fq_dequeue() can return NULL while some packets are
elligible for immediate transmit.
In this case, more than one iteration is needed to refill pband->credit.
With default parameters (weights 589824 196608 65536) bug can trigger
if large BIG TCP packets are sent to the lowest priority band.

The pwm1_enable attribute of the pwmfan driver influences the mode of
operation, especially in case of a requested pwm1 duty cycle of zero.
Especially setting pwm1_enable to two, should keep the pwm controller
enabled even if the duty cycle is set to zero [1].
This is not the case at the moment, as the pwm controller is disabled
always if pwm1 is set to zero.
This commit tries to fix this behavior.

Add support for the OrangePi NEO-01. It uses different registers for PWM
manual mode, set PWM, and read fan speed than previous devices. Valid PWM
input and duty cycle is 1-244, we scale this from 1-255 to maintain
compatibility with the existing interface.
Add OneXPlayer 2 series, OneXFly, and X1 series models. The 2/X1 series use
new registers for turbo button takeover and read fan speed. X1 has an Intel
variant so change the CPU detection at init to only check for the affected
devices. While at it, adjust formatting of some constants and reorder all
cases alphabetically for consistency. Rename OXP_OLD constants to OXP_MINI
for disambiguation. Update code comments for clarity.

Some of the newer Microsoft Surface devices (such as the Surface Book

Module (the embedded controller on those devices). Add a basic driver
to read out the temperature values of those sensors.
The EC can have up to 16 thermal sensors connected via a single
sub-device, each providing temperature readings and a label string.

the device's dedicated regulator.

Checking three configuration register bits and the manufacturer ID
register to auto-detect LM92 is a bit vague. Repeat twice on replicated
register addresses to improve detection accuracy. Check the manufacturer
ID first and bail out immediately without reading the other register if
there is a mismatch to reduce the number of i2c transfers needed in that
case. Also explicitly test for an error from reading the configuration
register to avoid potential situations where the returned error masked
against 0xe0 is 0.
While at it, drop "lm92: Found National Semiconductor LM92 chip" detection
noise.

Use of_property_present() to test for property presence rather than

If the GSC FW fails to load the GSC HW hangs permanently; the only ways
to recover it are FLR or D3cold entry, with the former only being
supported on driver unload and the latter only on DGFX, for which we
don't need to load the GSC. Therefore, if GSC fails to load there is no
need to try again because the HW is stuck in the error state and the
submission to load the FW would just hang the GSCCS.
Note that, due to wa_14015076503, on MTL the GuC escalates all GSCCS
hangs to full GT resets, which would trigger a new attempt to load the
GSC FW in the post-reset HW re-init; this issue is also fixed by not
attempting to load the GSC FW after an error.

The return variable 'ret' at btrfs_reclaim_sweep() is never assigned if
none of the space infos is reclaimable (for example if periodic reclaim
is disabled, which is the default), so we return an undefined value.
This can be fixed my making btrfs_reclaim_sweep() not return any value
as well as do_reclaim_sweep() because:
1) do_reclaim_sweep() always returns 0, so we can make it return void;
2) The only caller of btrfs_reclaim_sweep() (btrfs_reclaim_bgs()) doesn't
care about its return value, and in its context there's nothing to do
about any errors anyway.
Therefore remove the return value from btrfs_reclaim_sweep() and
do_reclaim_sweep().

Nicolin Chen says:
=========
IOMMU_RESV_SW_MSI is a unique region defined by an IOMMU driver. Though it
is eventually used by a device for address translation to an MSI location
(including nested cases), practically it is a universal region across all
domains allocated for the IOMMU that defines it.
Currently IOMMUFD core fetches and reserves the region during an attach to
an hwpt_paging. It works with a hwpt_paging-only case, but might not work
with a nested case where a device could directly attach to a hwpt_nested,
bypassing the hwpt_paging attachment.
Move the enforcement forward, to the hwpt_paging allocation function. Then
clean up all the SW_MSI related things in the attach/replace routine.
=========
Based on v6.11-rc5 for dependencies.
* nesting_reserved_regions: (562 commits)
iommufd/device: Enforce reserved IOVA also when attached to hwpt_nested
Linux 6.11-rc5
...
|
|
Currently, device reserved regions are only enforced when the device is
attached to an hwpt_paging. In other words, if the device gets attached to
an hwpt_nested directly, the parent hwpt_paging of the hwpt_nested's would
not enforce those reserved IOVAs. This works for most of reserved region
types, but not for IOMMU_RESV_SW_MSI, which is a unique software defined
window, required by a nesting case too to setup an MSI doorbell on the
parent stage-2 hwpt/domain.
Kevin pointed out in 1 that:
1) there is no usage using up closely the entire IOVA space yet,
2) guest may change the viommu mode to switch between nested and paging
then VMM has to take all devices' reserved regions into consideration
anyway, when composing the GPA space.
So it would be actually convenient for us to also enforce reserved IOVA
onto the parent hwpt_paging, when attaching a device to an hwpt_nested.
Repurpose the existing attach/replace_paging helpers to attach device's
reserved IOVAs exclusively.
Add a new find_hwpt_paging helper, which is only used by these reserved
IOVA functions, to allow an IOMMUFD_OBJ_HWPT_NESTED hwpt to redirect to
its parent hwpt_paging. Return a NULL in these two helpers for any new
HWPT type in the future.
