Add support for starting a polling timer in case an interrupt is not
available. This helps to keep the VPU functional in SoCs such as AM62A,
where the hardware interrupt hookup may not be present due to an SoC errata
[1].
The timer is shared across all instances of encoders and decoders and is
started when the first instance of an encoder or decoder is opened and
stopped when the last instance is closed, thus avoiding per instance
polling and saving CPU bandwidth. As VPU driver manages this instance
related tracking and synchronization, the aforementioned shared timer
related polling logic is implemented within the VPU driver itself. This
scheme may also be useful in general too (even if irq is present) for
non-realtime multi-instance VPU use-cases (for e.g 32 instances of VPU
being run together) where system is running already under high interrupt
load and switching to polling may help mitigate this as the polling thread
is shared across all the VPU instances.
Hrtimer is chosen for polling here as it provides precise timing and
scheduling and the API seems better suited for periodic polling task such
as this. As a general rule of thumb,
Worst case latency with hrtimer = Actual latency (achievable with irq)
+ Polling interval
NOTE (the meaning of terms used above is as follows):
- Latency: Time taken to process one frame
- Actual Latency : Time taken by hardware to process one frame and signal
it to OS (i.e. if latency that was possible to achieve if irq line was
present)
There is a trade-off between latency and CPU usage when deciding the value
for polling interval. With aggressive polling intervals (i.e. going with
even lesser values) the CPU usage increases although worst case latencies
get better. On the contrary, with greater polling intervals worst case
latencies will increase although the CPU usage will decrease.
The 5ms offered a good balance between the two as we were able to reach
close to actual latencies (as achievable with irq) without incurring too
much of CPU as seen in below experiments and thus 5ms is chosen as default
polling interval.
- 1x 640x480@25 Encoding using different hrtimer polling intervals [2]
- 4x 1080p30 Transcode (File->decode->encode->file) irq vs polling
comparison [3]
- 1x 1080p Transcode (File->decode->encode->file) irq vs polling comparison
[4]
- 1080p60 Streaming use-case irq vs polling comparison [5]
- 1x 1080p30 sanity decode and encode tests [6]
The polling interval can also be changed using vpu_poll_interval module
param in case user want to change it as per their use-case requirement
keeping in mind above trade-off.
Parse the irq number and if not present, initialize the hrtimer and the
polling worker thread before proceeding with v4l2 device registrations.
Based on interrupt status, we use a worker thread to iterate over the
interrupt status for each instance and send completion event as being done
in irq thread function.
Move the core functionality of the irq thread function to a separate
function wave5_vpu_handle_irq so that it can be used by both the worker
thread when using polling mode and irq thread when using interrupt mode.
Protect the hrtimer access and instance list with device specific mutex
locks to avoid race conditions while different instances of encoder and
decoder are started together.

The writes to setipnum_le/be register for APLIC in MSI-mode have special
consideration for level-triggered interrupts as-per the section "4.9.2
Special consideration for level-sensitive interrupt sources" of the RISC-V
AIA specification.
Particularly, the below text from the RISC-V AIA specification defines
the behaviour of writes to setipnum_le/be register for level-triggered
interrupts:
"A second option is for the interrupt service routine to write the
APLIC’s source identity number for the interrupt to the domain’s
setipnum register just before exiting. This will cause the interrupt’s
pending bit to be set to one again if the source is still asserting
an interrupt, but not if the source is not asserting an interrupt."
Fix setipnum_le/be write emulation for in-kernel APLIC by implementing
the above behaviour in aplic_write_pending() function.

syzbot reported an ext4 panic during a page fault where found a
journal handle when it didn't expect to find one. The structure
it tripped over had a value of 'TRAN' in the first entry in the
structure, and that indicates it tripped over a struct xfs_trans
instead of a jbd2 handle.
The reason for this is that the page fault was taken during a
copy-out to a user buffer from an xfs bulkstat operation. XFS uses
an "empty" transaction context for bulkstat to do automated metadata
buffer cleanup, and so the transaction context is valid across the
copyout of the bulkstat info into the user buffer.
We are using empty transaction contexts like this in XFS to reduce
the risk of failing to release objects we reference during the
operation, especially during error handling. Hence we really need to
ensure that we can take page faults from these contexts without
leaving landmines for the code processing the page fault to trip
over.
However, this same behaviour could happen from any other filesystem
that triggers a page fault or any other exception that is handled
on-stack from within a task context that has current->journal_info
set. Having a page fault from some other filesystem bounce into XFS
where we have to run a transaction isn't a bug at all, but the usage
of current->journal_info means that this could result corruption of
the outer task's journal_info structure.
The problem is purely that we now have two different contexts that
now think they own current->journal_info. IOWs, no filesystem can
allow page faults or on-stack exceptions while current->journal_info
is set by the filesystem because the exception processing might use
current->journal_info itself.
If we end up with nested XFS transactions whilst holding an empty
transaction, then it isn't an issue as the outer transaction does
not hold a log reservation. If we ignore the current->journal_info
usage, then the only problem that might occur is a deadlock if the
exception tries to take the same locks the upper context holds.
That, however, is not a problem that setting current->journal_info
would solve, so it's largely an irrelevant concern here.
IOWs, we really only use current->journal_info for a warning check
in xfs_vm_writepages() to ensure we aren't doing writeback from a
transaction context. Writeback might need to do allocation, so it
can need to run transactions itself. Hence it's a debug check to
warn us that we've done something silly, and largely it is not all
that useful.
So let's just remove all the use of current->journal_info in XFS and
get rid of all the potential issues from nested contexts where
current->journal_info might get misused by another filesystem
context.

If a filesystem has a busted stripe alignment configuration on disk
(e.g. because broken RAID firmware told mkfs that swidth was smaller
than sunit), then the filesystem will refuse to mount due to the
stripe validation failing. This failure is triggering during distro
upgrades from old kernels lacking this check to newer kernels with
this check, and currently the only way to fix it is with offline
xfs_db surgery.
This runtime validity checking occurs when we read the superblock
for the first time and causes the mount to fail immediately. This
prevents the rewrite of stripe unit/width via
mount options that occurs later in the mount process. Hence there is
no way to recover this situation without resorting to offline xfs_db
rewrite of the values.
However, we parse the mount options long before we read the
superblock, and we know if the mount has been asked to re-write the
stripe alignment configuration when we are reading the superblock
and verifying it for the first time. Hence we can conditionally
ignore stripe verification failures if the mount options specified
will correct the issue.
We validate that the new stripe unit/width are valid before we
overwrite the superblock values, so we can ignore the invalid config
at verification and fail the mount later if the new values are not
valid. This, at least, gives users the chance of correcting the
issue after a kernel upgrade without having to resort to xfs-db
hacks.
