This PR adds the driver for Reduced Serial Bus (RSB) on Allwinner A64 SoC. The RSB Driver will be called by the upcoming Power Mgmt IC Driver for PINE64 PinePhone, to power on the LCD Display.
`arch/arm64/src/a64/Kconfig`: Added the Kconfig option for "A64 Peripheral Selection > RSB" (`CONFIG_A64_RSB`), which enables the RSB Driver
`arch/arm64/src/a64/hardware/a64_memorymap.h`: Added the Base Address for RSB
`arch/arm64/src/a64/Make.defs`: Added the RSB Driver to the Makefile
`arch/arm64/src/a64/a64_de.c`: Increase PLL Timeout for Allwinner A64 Display Engine
`boards/arm64/a64/pinephone/configs/nsh/defconfig`: Set PinePhone Board Config `CONFIG_BOARD_LOOPSPERMSEC` to the value computed by `calib_udelay`
`arch/arm64/src/a64/a64_rsb.c`, `a64_rsb.h`: RSB Driver for Allwinner A64
`platforms/arm/a64/boards/pinephone/index.rst`: Added RSB as supported peripheral for PinePhone
_assert is a kernel procedure, entered via system call to make the core
dump in privileged mode.
Running exit() from this context is not OK as it runs the registered
exit functions and flushes streams, which must not be done
from privileged mode as it is a security hole.
Thus, implement assert() into user space (again) and remove the exit()
call from the kernel procedure.
Instantiate the correct address environment when reading the process's
argument vector. Otherwise doing this will crash the system every time,
causing a recursive assert loop.
Also try to do a bit of sanity checking before attempting to read the
process's memory, it might be in a bad state in which case this will
fail anyway.
I don't know how to handle this properly as I don't know what this
symbol table is supposed to do. Most likely the part that uses the
symbol table needs to be patched also...
This is preparation for flushing streams from user space, like it should
be done.
- Move tg_streamlist (group, kernel space) ->
ta_streamlist (TLS, user space)
- Access stream list via tg_info in kernel
- Access stream list via TLS in user space
- Remove / rename nxsched_get_streams -> lib_getstreams
- Remove system call for nxsched_get_streams
- in NuttX 11.x and 12.x the nuttx entry point
for the sama5d2-xult board changed to 0x20008E20
(from 0x2008040).
This change updates defconfigs and the README.txt
to reflect that.
- no code changes
This PR adds the driver for Display Engine 2.0 on Allwinner A64 SoC. The Display Engine Driver will be called by the upcoming LCD Driver for PINE64 PinePhone.
`arch/arm64/src/a64/Kconfig`: Added the Kconfig option for "A64 Peripheral Selection > DE" (`CONFIG_A64_DE`), which enables the Display Engine Driver
`arch/arm64/src/a64/hardware/a64_memorymap.h`: Added the Base Address for Display Engine
`arch/arm64/src/a64/Make.defs`: Added the Display Engine Driver to the Makefile
`boards/arm64/a64/pinephone/configs/nsh/defconfig`: Removed Scheduler Debug Info (`CONFIG_DEBUG_SCHED_INFO`) from the PinePhone Board Config, because it garbles the Console Output.
`arch/arm64/src/a64/a64_de.c`, `a64_de.h`: Display Engine Driver for Allwinner A64
`platforms/arm/a64/boards/pinephone/index.rst`: Added Display Engine as supported peripheral for PinePhone
