The PASID_FLAG_PAGE_SNOOP and PASID_FLAG_PWSNP constants are identical.
This will cause the pasid code to always set both or neither of the
PGSNP and PWSNP bits in PASID table entries. However, PWSNP is a
reserved bit if SMPWC is not set in the IOMMU's extended capability
register, even if SC is supported.
This has resulted in DMAR errors when testing the iommufd code on an
Arrow Lake platform. With this patch, those errors disappear and the
PASID table entries look correct.

The COMMAND1 register bits [29:28] set the SPI mode, which controls
the clock idle level. When a transfer ends, tegra_spi_transfer_end()
writes def_command1_reg back to restore the default state, but this
register value currently lacks the mode bits. This results in the
clock always being configured as idle low, breaking devices that
need it high.
Fix this by storing the mode bits in def_command1_reg during setup,
to prevent this field from always being cleared.

Pull dcache fixes from Al Viro:
"A couple of regression fixes for the tree-in-dcache series this cycle"
* tag 'pull-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
functionfs: use spinlock for FFS_DEACTIVATED/FFS_CLOSING transitions
rust_binderfs: fix a dentry leak
|
|
When all files are closed, functionfs needs ffs_data_reset() to be
done before any further opens are allowed.
During that time we have ffs->state set to FFS_CLOSING; that makes
->open() fail with -EBUSY. Once ffs_data_reset() is done, it
switches state (to FFS_READ_DESCRIPTORS) indicating that opening
that thing is allowed again. There's a couple of additional twists:
* mounting with -o no_disconnect delays ffs_data_reset()
from doing that at the final ->release() to the first subsequent
open(). That's indicated by ffs->state set to FFS_DEACTIVATED;
if open() sees that, it immediately switches to FFS_CLOSING and
proceeds with doing ffs_data_reset() before returning to userland.
* a couple of usb callbacks need to force the delayed
transition; unfortunately, they are done in locking environment
that does not allow blocking and ffs_data_reset() can block.
As the result, if these callbacks see FFS_DEACTIVATED, they change
state to FFS_CLOSING and use schedule_work() to get ffs_data_reset()
executed asynchronously.
Unfortunately, the locking is rather insufficient. A fix attempted
in e5bf5ee26663 ("functionfs: fix the open/removal races") had closed
a bunch of UAF, but it didn't do anything to the callbacks, lacked
barriers in transition from FFS_CLOSING to FFS_READ_DESCRIPTORS
_and_ it had been too heavy-handed in open()/open() serialization -
I've used ffs->mutex for that, and it's being held over actual IO on
ep0, complete with copy_from_user(), etc.
Even more unfortunately, the userland side is apparently racy enough
to have the resulting timing changes (no failures, just a delayed
return of open(2)) disrupt the things quite badly. Userland bugs
or not, it's a clear regression that needs to be dealt with.
Solution is to use a spinlock for serializing these state checks and
transitions - unlike ffs->mutex it can be taken in these callbacks
and it doesn't disrupt the timings in open().
We could introduce a new spinlock, but it's easier to use the one
that is already there (ffs->eps_lock) instead - the locking
environment is safe for it in all affected places.
Since now it is held over all places that alter or check the
open count (ffs->opened), there's no need to keep that atomic_t -
int would serve just fine and it's simpler that way.

The initial state of dma_needs_unmap may be false, but change to true
while mapping the data iterator. Enabling swiotlb is one such case that
can change the result. The nvme driver needs to save the mapped dma
vectors to be unmapped later, so allocate as needed during iteration
rather than assume it was always allocated at the beginning. This fixes
a NULL dereference from accessing an uninitialized dma_vecs when the
device dma unmapping requirements change mid-iteration.

Current design will power off all dependent GPC power domains in
imx8mp_blk_ctrl_suspend(), even though the user device has enabled
wakeup capability. The result is that wakeup function never works
for such device.
An example will be USB wakeup on i.MX8MP. PHY device '382f0040.usb-phy'
is attached to power domain 'hsioblk-usb-phy2' which is spawned by hsio
block control. A virtual power domain device 'genpd:3:32f10000.blk-ctrl'
is created to build connection with 'hsioblk-usb-phy2' and it depends on
GPC power domain 'usb-otg2'. If device '382f0040.usb-phy' enable wakeup,
only power domain 'hsioblk-usb-phy2' keeps on during system suspend,
power domain 'usb-otg2' is off all the time. So the wakeup event can't
happen.
In order to further establish a connection between the power domains
related to GPC and block control during system suspend, register a genpd
power on/off notifier for the power_dev. This allows us to prevent the GPC
power domain from being powered off, in case the block control power
domain is kept on to serve system wakeup.

The mgag200_bmc_stop_scanout() function is called by the .atomic_disable()
handler for the MGA G200 VGA BMC encoder. This function performs a few
register writes to inform the BMC of an upcoming mode change, and then
polls to wait until the BMC actually stops.
The polling is implemented using a busy loop with udelay() and an iteration
timeout of 300, resulting in the function blocking for 300 milliseconds.
The function gets called ultimately by the output_poll_execute work thread
for the DRM output change polling thread of the mgag200 driver:

On a server running ptp4l with the mgag200 driver loaded, we found that
ptp4l would sometimes get blocked from execution because of this busy
waiting loop.
Every so often, approximately once every 20 minutes -- though with large
variance -- the output_poll_execute() thread would detect some sort of
change that required performing a hotplug event which results in attempting
to stop the BMC scanout, resulting in a 300msec delay on one CPU.
On this system, ptp4l was pinned to a single CPU. When the
output_poll_execute() thread ran on that CPU, it blocked ptp4l from
executing for its 300 millisecond duration.
This resulted in PTP service disruptions such as failure to send a SYNC
message on time, failure to handle ANNOUNCE messages on time, and clock
check warnings from the application. All of this despite the application
being configured with FIFO_RT and a higher priority than the background
workqueue tasks. (However, note that the kernel did not use
CONFIG_PREEMPT...)
It is unclear if the event is due to a faulty VGA connection, another bug,
or actual events causing a change in the connection. At least on the system
under test it is not a one-time event and consistently causes disruption to
the time sensitive applications.
The function has some helpful comments explaining what steps it is
attempting to take. In particular, step 3a and 3b are explained as such:
3a - The third step is to verify if there is an active scan. We are
waiting on a 0 on remhsyncsts (<XSPAREREG<0>.
3b - This step occurs only if the remove is actually scanning. We are
waiting for the end of the frame which is a 1 on remvsyncsts
(<XSPAREREG<1>).
The actual steps 3a and 3b are implemented as while loops with a
non-sleeping udelay(). The first step iterates while the tmp value at
position 0 is *not* set. That is, it keeps iterating as long as the bit is
zero. If the bit is already 0 (because there is no active scan), it will
iterate the entire 300 attempts which wastes 300 milliseconds in total.
This is opposite of what the description claims.
The step 3b logic only executes if we do not iterate over the entire 300
attempts in the first loop. If it does trigger, it is trying to check and
wait for a 1 on the remvsyncsts. However, again the condition is actually
inverted and it will loop as long as the bit is 1, stopping once it hits
zero (rather than the explained attempt to wait until we see a 1).
Worse, both loops are implemented using non-sleeping waits which spin
instead of allowing the scheduler to run other processes. If the kernel is
not configured to allow arbitrary preemption, it will waste valuable CPU
time doing nothing.
There does not appear to be any documentation for the BMC register
interface, beyond what is in the comments here. It seems more probable that
the comment here is correct and the implementation accidentally got
inverted from the intended logic.
Reading through other DRM driver implementations, it does not appear that
the .atomic_enable or .atomic_disable handlers need to delay instead of
sleep. For example, the ast_astdp_encoder_helper_atomic_disable() function
calls ast_dp_set_phy_sleep() which uses msleep(). The "atomic" in the name
is referring to the atomic modesetting support, which is the support to
enable atomic configuration from userspace, and not to the "atomic context"
of the kernel. There is no reason to use udelay() here if a sleep would be
sufficient.
Replace the while loops with a read_poll_timeout() based implementation
that will sleep between iterations, and which stops polling once the
condition is met (instead of looping as long as the condition is met). This
aligns with the commented behavior and avoids blocking on the CPU while
doing nothing.
Note the RREG_DAC is implemented using a statement expression to allow
working properly with the read_poll_timeout family of functions. The other
RREG_<TYPE> macros ought to be cleaned up to have better semantics, and
several places in the mgag200 driver could make use of RREG_DAC or similar
RREG_* macros should likely be cleaned up for better semantics as well, but
that task has been left as a future cleanup for a non-bugfix.

This trace occurs because vlan_for_each() is called within

The gve driver's "rx_dropped" statistic, exposed via `ethtool -S`,
incorrectly includes `rx_buf_alloc_fail` counts. These failures
represent an inability to allocate receive buffers, not true packet
drops where a received packet is discarded. This misrepresentation can
lead to inaccurate diagnostics.
This patch rectifies the ethtool "rx_dropped" calculation. It removes
`rx_buf_alloc_fail` from the total and adds `xdp_tx_errors` and
`xdp_redirect_errors`, which represent legitimate packet drops within
the XDP path.

The driver and the NIC share a region in memory for stats reporting.
The NIC calculates its offset into this region based on the total size
of the stats region and the size of the NIC's stats.
When the number of queues is changed, the driver's stats region is
resized. If the queue count is increased, the NIC can write past
the end of the allocated stats region, causing memory corruption.
If the queue count is decreased, there is a gap between the driver
and NIC stats, leading to incorrect stats reporting.
This change fixes the issue by allocating stats region with maximum
size, and the offset calculation for NIC stats is changed to match
with the calculation of the NIC.

in the right order, and we would see nocat records with asserts
in them.
Add the rpc level sequence number support.

If amdgpu_amdkfd_gpuvm_free_memory_of_gpu() fails after kgd_mem is
removed from validate_list, the mem handle still lingers in the KFD idr.
This means when process is terminated,
kfd_process_free_outstanding_kfd_bos() will call
amdgpu_amdkfd_gpuvm_free_memory_of_gpu() again resulting in double
deletion.
To avoid this -
(a) Check if list is empty before deleting it
(b) Rearragne amdgpu_amdkfd_gpuvm_free_memory_of_gpu() such that it can
be safely called again if it returns failure the first time.

There is nothing wrong if in_shaper_func type is DISTRIBUTED POINTS.
Remove the assert placed for a TODO to avoid misinterpretations.
