Create an auxiliary evlist for overwritable events.
Before mmap, build this evlist and set 'overwrite' and 'backward'
attribute. Since perf_evlist__mmap_ex() only maps events when
evsel->overwrite matches evlist's corresponding attributes, with
these two evlists an event goes to either rec->evlist
Before this patch, when using overwritable ring buffer on an old
kernel, error message is misleading:
# ~/perf record -m 1 -e raw_syscalls:*/overwrite/ -a
Error:
The raw_syscalls:sys_enter event is not supported.
This patch output clear error message to tell user his/her kernel
is too old:
#
overwrite_evt_state is introduced to reflect the state of overwritable
ring buffers. It is a state machine with 3 states:
RUNNING --(1)--> DATA_PENDING --(2)--> EMPTY
^ ^ |
| |___(disallow)___/|
||
There's no need to receive events from overwritable ring buffer. Instead,
perf should make them run background until something happen. This patch
makes normal events from overwrite events ignored.
Overwritable events must be mapped readonly and backward, so if evlist
and evsel is not match (evsel-

Hi Liviu,
Humble request: For the future please split things into manageable
hunks. I doubt you wrote the whole thing in one go, right ?
At the very minimum you could have introduced DP500 support initially
and then DP550 and DP650 as follow up commits.

The volume/mute feature unit was dummy implementation
since this driver creation (2009) and never had
real volume control or mute functionality.
Since it was never implemented, drop it and
increase maintainability of the driver.
Those who want real volume/mute support may
revert this patch and add
Abstract the peripheral side ALSA sound card code from
the f_uac2 function into a component that can be called
by various functions, so the various flavors can be split
apart and selectively reused.
Visible changes:
- add uac_params structure to pass audio paramteres for
gaudio_setup
- make A

I came to this patch series when wanted to do two things:
- use UAC1 as virtual ALSA sound card on gadget side,
just like UAC2 is used so it's possible to do rate
resampling
- have both playback/capture support in UAC1
Since I wanted to have same behavior for both UAC1/UAC2,
obviously I've
Reuse existing u_audio core utilities making f_uac1
much simpler.
This also drops previous f_uac1 approach (write audio
samples directly to existing ALSA sound card) and moves
to more generic/flexible one - create an f_uac1 ALSA
sound card that represents USB Audio function and
allows to be used b
Simplify f_uac2 by removing platform driver/device
creation; use composite's usb_gadget device as
parent for sound card and for debug prints.
This removes extra layer of code without any functional
change.

Add capture support (gadget->host) to the f_uac1
driver. This requires renaming of some descriptors,
enums etc that were used exclusively for playback
path. To make it meaningful, f_uac2 driver naming
convention has been used.
By default, capture interface has 48000kHz/2ch
configuration, same as p

Quoting "Nicholas A. Bellinger" :
So AFAICT for delayed commands, the above patch ends up skipping these
three checks subsequently when doing __target_execute_cmd() directly
from target_restart_delayed_cmds(), no..?
After pondering this some more, what about moving these checks into
__target

With the introduction of the ISA_BUS_API Kconfig option, ISA-style
drivers may be built for X86_64 architectures. This patch changes the
ISA Kconfig option dependency of the WinSystems EBC-C384 watchdog timer
driver to ISA_BUS_API, thus allowing it to build for X86_64 as it is
expected to.

Several modern devices, such as PC/104 cards, are expected to run on
modern systems via an ISA bus interface. Since ISA is a legacy interface
for most modern architectures, ISA support should remain disabled in
general. Support for ISA-style drivers should be enabled on a per driver
basis.

Changes in v3:
- Remove redundant X86 dependency from the X86 ISA_BUS Kconfig option
Changes in v2:
- Adjusted preprocessor compilation conditional in include/linux/isa.h
to use CONFIG_ISA_BUS_API in order to link the correct ISA bus
driver function definitions when available
