vfio_pin_pages() accepts an array of unrelated iova pfns and processes
each to return the physical pfn. When dealing with large arrays of
contiguous iovas, vfio_iommu_type1_pin_pages is very inefficient because
it is processed page by page.In this case, we can divide the iova pfn
array into

Hey All,
So just wanted to send another revision of my patch series
of performance optimizations to the dma-buf system heap, this
time against drm-misc-next.
This series reworks the system heap to use sgtables, and then
consolidates the pagelist method from the heap-helpers into the
CMA heap.
The introduction of ufshcd_dme_configure_adapt() refactored out
duplication from the Mediatek and Qualcomm drivers.
Both these implementations had the logic of:
gear_tx == UFS_HS_G4 => PA_INITIAL_ADAPT
gear_tx != UFS_HS_G4 => PA_NO_ADAPT
but now both implementations pass PA_INITIAL_ADAPT

Reader optimistic spinning is helpful when the reader critical section

the chance that a reader can get the lock as writer optimistic spinning
disproportionally favors writers much more than readers.

reader gets the lock, all
The lock handoff bit is added in commit 4f23dbc1e657 ("locking/rwsem:
Implement lock handoff to prevent lock starvation") to avoid lock
starvation. However, allowing readers to do optimistic spinning does
introduce an unlikely scenario where lock starvation can happen.
The lock handoff bit may
The atomic count value right after reader count increment can be useful

passed down to rwsem_down_read_slowpath() to be used when appropriate.

If the optimistic spinning queue is empty and the rwsem does not have
the handoff or write-lock bits set, it is actually not necessary to
call rwsem_optimistic_spin() to spin on it. Instead, it can steal the
lock directly as its reader bias is in the count already. If it is

Add utilities to new/free an ids hashmap, as well as to union. Add
testing of the union. Unioning hashmaps will be used when parsing the
metric, if a value is known then the hashmap is unnecessary, otherwise
we need to union together all the event ids to compute their values for
reporting.
For a metric like:
EVENT1 if #smt_on else EVENT2
currently EVENT1 and EVENT2 will be measured and then when the metric is
reported EVENT1 or EVENT2 will be printed depending on the value from
smt_on() during the expr parsing. Computing both events is unnecessary and
can lead to multiplexing as
A later change will remove the notion of other, rename the function to
expr__find_ids as this is what it populates.

If during computing a metric an event (id) is missing the parsing
aborts. A later patch will make it so that events that aren't used in
the output are deliberately omitted, in which case we don't want the
abort. Modify the missing ID case to report NAN for these cases.

A later change to parsing the ids out (in expr__find_other) will
potentially drop hashmaps and so it is more convenient to move
expr_parse_ctx to have a hashmap pointer rather than a struct value. As
this pointer must be freed, rather than just going out of scope,
add expr__ctx_new and

The current semantic for napi_consume_skb() is that caller need
to provide non-zero budget when calling from NAPI context, and
breaking this semantic will cause hard to debug problem, because
_kfree_skb_defer() need to run in atomic context in order to push
the skb to the particular cpu'
This patch introduces a lockdep_assert_in_softirq() interface and
uses it to assert the case when napi_consume_skb() is not called in
the softirq context.

V2: Use lockdep instead of one-off Kconfig knob

The remoteproc framework provides sysfs interfaces for changing
the firmware name and for starting/stopping a remote processor
through the sysfs files 'state' and 'firmware'. The 'recovery'
sysfs file can also be used similarly to control the error recovery
state machine of a remoteproc. These
Hi All,
This is a refresh of the unaccepted patches from an old series [1].
Patches 2 and 3 from that series were merged and these are rebased and
revised versions of the same patches. I had forgotten about these patches,
and am resurrecting these again. Patches are on top of latest 5.10-rc4.
The Wakeup M3 remote processor is controlled by the wkup_m3_ipc
client driver, so set the newly introduced 'deny_sysfs_ops' flag
to not allow any overriding of the remoteproc firmware or state
from userspace.

v2: rebased version, no code changes, patch title
The remoteproc core performs automatic boot and shutdown of a remote
processor during rproc_add() and rproc_del() for remote processors
supporting 'auto-boot'. The remoteproc devices not using 'auto-boot'
require either a remoteproc client driver or a userspace client to
use the sysfs 'state'
