1. add support to join main task
| static pthread_t self;
|
| static void *join_task(void *arg)
| {
| int ret;
| ret = pthread_join(self, NULL); <--- /* Fix Task could not be joined */
| return NULL;
| }
|
| int main(int argc, char *argv[])
| {
| pthread_t thread;
|
| self = pthread_self();
|
| pthread_create(&thread, NULL, join_task, NULL);
| sleep(1);
|
| pthread_exit(NULL);
| return 0;
| }
2. Detach active thread will not alloc for additional join, just update the task flag.
3. Remove the return value waiting lock logic (data_sem),
the return value will be stored in the waiting tcb.
4. Revise the return value of pthread_join(), consistent with linux
e.g:
Joining a detached and canceled thread should return EINVAL, not ESRCH
https://pubs.opengroup.org/onlinepubs/009695399/functions/pthread_join.html
[EINVAL]
The value specified by thread does not refer to a joinable thread.
NOTE:
This PR will not increase stack usage, but struct tcb_s will increase 32 bytes.

Adjust the v4l2 framework to support both capture and v4l2m2m,
and can easily add other v4l2 features.

Some stm32 has alternate USART6 pinout on G9/G14 but others have it
on A12/A11. Unfortunately it's very difficult to make proper ifdefs for
this since position is based on package (and pincount) and not chip
itself. Creating such list would take a lot of time. Because of that
I just added another possible config for this pin and moved responsibility
of proper selection onto board code.

Onewire driver wants to use "struct up_dev_s *priv", which is extracted
from "struct uart_dev_s" and "struct inode". But inode and uart dev are
only declared when TERMIOS or BSDCOMPAT is also enabled. Without these
driver fails to compile with missing declaration errors. Adding some
additional "#if defined()" to these declarations fix the issue and driver
compiles and works properly (tested with ds18b20 temp sensor).

This driver is used with QEMU, to make it possible
to use networking.
This is not the MAC in ESP32, however, it can be used with QEMU.
The code was shamelessly copied from 31dac92e5f
Because the ratio between API value and ISX019 register value
is 128 : 90 about HUE, some different API values become the
same register value.
So, store the value specified by application in setting,
and return the stored value in getting so that the gotten value
is the same as the setting value by application.
About IMGSENSOR_ID_EXPOSURE_AUTO, IMGSENSOR_ID_ISO_SENSITIVITY_AUTO,
and IMGSENSOR_ID_EXPOSURE_METERING, enumerations are defined.
So, control type should be not integer but integer menu.
About parameter whose register size is less than 4 bytes,
when transfer read value to API parameter, cast appropriately
to avoid the following problems.
- Read value includes garbage value
- Negative value becomes huge positive value
Modify control id definition to avoid duplication even if
the control ids belong to the same control class.
Also, not refer to control class in driver.
This fixes calls like memmem("hello", 5, "lo", 2);
Also zero-length needle is deemed to exist at beginning of haystack.
This behavior matches memmem() on Linux, FreeBSD, NetBSD and OpenBSD.

The delete flag is not synchronized with the life cycle of the group,
if the flag set before waitpid(), the tcb will be mistakenly deleted
by group_del_waiter(), use-after-free will happen.
