Summary:
- This commit changes spinlock APIs (spin_lock_irqsave/spin_unlock_irqrestore)
- In the previous implementation, the global spinlock (i.e. g_irq_spin) was used.
- This commit allows to use caller specific spinlock but also supports to use
g_irq_spin for backword compatibility (In this case, NULL must be specified)
Impact:
- None
Testing:
- Tested with the following configurations
- spresnse:wifi, spresense:wifi_smp
- esp32-devkitc:smp (QEMU), sabre6-quad:smp (QEMU)
- maxi-bit:smp (QEMU), sim:smp
- stm32f4discovery:wifi

Summary:
- This commit fixes compile errors in esp32_spiflash.c and
esp32_wifi_adapter.c with CONFIG_SMP=y
Impact:
- SMP only
Testing:
- Tested with esp32-devkitc:wapi
- NOTE: the following configs need to be added.
+CONFIG_SMP=y
+CONFIG_SMP_IDLETHREAD_STACKSIZE=3072
+CONFIG_SMP_NCPUS=2
+CONFIG_SPINLOCK_IRQ=y

SMP was broken because the ROM memory wasn't set correctly. Some
regions were shared with the ROM code.

Requiring the size to be a multiple of 3 is a very strange restriction.
It doesn't even work with the default value of SPI_SLAVE_BUFSIZE.
I guess it was a typo.
The original assertion was wrong because:
* cpuint numbers for edge interrupts are not dense
(while ESP32_CPUINT_NEDGEPERIPHS is 4, EPS32_CPUINT_EDGESET is not 0xf.)
* This function is used for level interrupts too
1. when sending a message in a group fails, exit immediately
2. when catch I2C error interrupt, close interrupt
3. clear clock configuration when deinit I2C
4. free I2C interrupt when deinit I2C
wget is missing from some system (like macOS and Windows native),
it's better to use curl to simplify build environment.

Summary:
- During repeating ostest with sabre-6quad:smp (QEMU),
I noticed that pthread_rwlock_test sometimes stops
- Finally, I found that nxtask_exit() released a critical
section too early before context switching which resulted in
selecting inappropriate TCB
- This commit fixes this issue by moving nxsched_resume_scheduler()
from nxtask_exit() to up_exit() and also removing
spin_setbit() and spin_clrbit() from nxtask_exit()
because the caller holds a critical section
- To be consistent with non-SMP cases, the above changes
were done for all CPU architectures
Impact:
- This commit affects all CPU architectures regardless of SMP
Testing:
- Tested with ostest with the following configs
- sabre-6quad:smp (QEMU, dev board), sabre-6quad:nsh (QEMU)
- spresense:wifi_smp
- sim:smp, sim:ostest
- maix-bit:smp (QEMU)
- esp32-devkitc:smp (QEMU)
- lc823450-xgevk:rndis

Summary:
- This commit fixes global IRQ control logic
- In previous implementation, g_cpu_irqset for a remote CPU was
set in sched_add_readytorun(), sched_remove_readytorun() and
up_schedule_sigaction()
- In this implementation, they are removed.
- Instead, in the pause handler, call enter_critical_setion()
which will call up_cpu_paused() then acquire g_cpu_irqlock
- So if a new task with irqcount > 1 restarts on the remote CPU,
the CPU will only hold a critical section. Thus, the issue such as
'POSSIBLE FOR TWO CPUs TO HOLD A CRITICAL SECTION' could be resolved.
- Fix nxsched_resume_scheduler() so that it does not call spin_clrbit()
if a CPU does not hold a g_cpu_irqset
- Fix nxtask_exit() so that it acquires g_cpu_irqlock
- Update TODO
Impact:
- All SMP implementations
Testing:
- Tested with smp, ostest with the following configurations
- Tested with spresense:wifi_smp (NCPUS=2,4)
- Tested with sabre-6quad:smp (QEMU, dev board)
- Tested with maix-bit:smp (QEMU)
- Tested with esp32-core:smp (QEMU)
- Tested with lc823450-xgevk:rndis
