Lorenzo Stoakes <lorenzo.stoakes@oracle.com> says:
If you wish to utilise a pidfd interface to refer to the current process or
thread then there is a lot of ceremony involved, looking something like:
pid_t pid = getpid();
int pidfd = pidfd_open(pid, PIDFD_THREAD);
if (pidfd < 0) {
... error handling ...
}
if (process_madvise(pidfd, iovec, 8, MADV_GUARD_INSTALL, 0)) {
... cleanup pidfd ...
... error handling ...
}
...
... cleanup pidfd ...
This adds unnecessary overhead + system calls, complicated error handling
and in addition pidfd_open() is subject to RLIMIT_NOFILE (i.e. the limit of
per-process number of open file descriptors), so the call may fail
spuriously on this basis.
Rather than doing this we can make use of sentinels for this purpose which can
be passed as the pidfd instead. This looks like:
if (process_madvise(PIDFD_SELF, iovec, 8, MADV_GUARD_INSTALL, 0)) {
... error handling ...
}
And avoids all of the aforementioned issues. This series introduces such
sentinels.
It is useful to refer to both the current thread from the userland's
perspective for which we use PIDFD_SELF, and the current process from the
userland's perspective, for which we use PIDFD_SELF_PROCESS.
There is unfortunately some confusion between the kernel and userland as to
what constitutes a process - a thread from the userland perspective is a
process in userland, and a userland process is a thread group (more
specifically the thread group leader from the kernel perspective). We
therefore alias things thusly:
* PIDFD_SELF_THREAD aliased by PIDFD_SELF - use PIDTYPE_PID.
* PIDFD_SELF_THREAD_GROUP alised by PIDFD_SELF_PROCESS - use PIDTYPE_TGID.
In all of the kernel code we refer to PIDFD_SELF_THREAD and
PIDFD_SELF_THREAD_GROUP. However we expect users to use PIDFD_SELF and
PIDFD_SELF_PROCESS.
This matters for cases where, for instance, a user unshare()'s FDs or does
thread-specific signal handling and where the user would be hugely confused
if the FDs referenced or signal processed referred to the thread group
leader rather than the individual thread.
Another use-case comes from Android. When installing multiple
MADV_GUARD_INSTALL guard pages they considered caching the result of
pidfd_open() for reuse. That however wouldn't work in shared libraries
where users can fork() in between such calls.
For now we only adjust pidfd_get_task() and the pidfd_send_signal() system
call with specific handling for this, implementing this functionality for
process_madvise(), process_mrelease() (albeit, using it here wouldn't
really make sense) and pidfd_send_signal().
We defer making further changes, as this would require a significant rework
of the pidfd mechanism.
The motivating case here is to support PIDFD_SELF in process_madvise(), so
this suffices for immediate uses. Moving forward, this can be further
expanded to other uses.

We explicitly test pidfd_send_signal(), however We defer testing of
mm-specific functionality which uses pidfd, namely process_madvise() and
process_mrelease() to mm testing (though note the latter can not be
sensibly tested as it would require the testing process to be dying).
We also correct the pidfd_open_test.c fields which refer to .request_mask
whereas the UAPI header refers to .mask, which otherwise break the import
of the UAPI header.

It is useful to be able to utilise the pidfd mechanism to reference the
current thread or process (from a userland point of view - thread group
leader from the kernel's point of view).
Therefore introduce PIDFD_SELF_THREAD to refer to the current thread, and
PIDFD_SELF_THREAD_GROUP to refer to the current thread group leader.
For convenience and to avoid confusion from userland's perspective we alias
these:
* PIDFD_SELF is an alias for PIDFD_SELF_THREAD - This is nearly always what
the user will want to use, as they would find it surprising if for
instance fd's were unshared()'d and they wanted to invoke pidfd_getfd()
and that failed.
* PIDFD_SELF_PROCESS is an alias for PIDFD_SELF_THREAD_GROUP - Most users
have no concept of thread groups or what a thread group leader is, and
from userland's perspective and nomenclature this is what userland
considers to be a process.
We adjust pidfd_get_task() and the pidfd_send_signal() system call with
specific handling for this, implementing this functionality for
process_madvise(), process_mrelease() (albeit, using it here wouldn't
really make sense) and pidfd_send_signal().

Enabling and disabling of DMC wakelock is already coupled with enabling
and disabling of dynamic DC states, which already depend on the DMC
being properly loaded. As such, we do not need to check if we already
have a DMC payload parsed in __intel_dmc_wl_supported().
Furthermore, the presence of such a check causes inconsistencies in the
refcount if the following sequence of events happen:
1. A call to one of the register accessors from intel_de.h is done
before the DMC payload is parsed. That causes intel_dmc_wl_get() to
be called. Suppose the register offset qualifies as needing the
wakelock.
In normal circumstances, the refcount would be incremented, but,
because __intel_dmc_wl_supported() returns false, the refcount is
untouched.
2. In a separate worker thread, the DMC firmware is parsed. Parsing of
the DMC payload is finished before the corresponding
intel_dmc_wl_put() from (1) is called.
3. When in the context of (1), intel_dmc_wl_put() gets called, now we
have __intel_dmc_wl_supported() returning true and we hit the
warning, because the code doesn't expect a zero refcount.
Let's remove that check, since it is unnecessary and causes the
inconsistency illustrated above.

Becially, this feature is used to fine-tune subtle difference that occur

If there was difference over 1%, it will apply with 1% increments by using

To use runtime convert rate (= Synchronous SRC Mode), user might uses

The internal mic boost on the Positivo ARN50 is too high.
Fix this by applying the ALC269_FIXUP_LIMIT_INT_MIC_BOOST fixup to the machine
to limit the gain.

commit 90de551c1b ("ASoC: simple-card-utils.c: enable multi Component
support") added muiti Component support, but was missing to add
dlc->of_node. Because of it, Sound device list will indicates strange
name if it was DPCM connection and driver supports dai->driver->dai_args,
like below
> aplay -l
card X: sndulcbmix [xxxx], device 0: fe.(null).rsnd-dai.0 (*) []
... ^^^^^^
It will be fixed by this patch
> aplay -l
card X: sndulcbmix [xxxx], device 0: fe.sound@ec500000.rsnd-dai.0 (*) []
... ^^^^^^^^^^^^^^
