db24306435 arch/assertion logic: Fix additional places where the test for an IDLE task is incorrect. It is not invalid in all configurations to check for PID==0. However, the logic fixed in these places lackes sufficient intelligence to find the right stack for the CPU IDLE thread and could still show the wrong stack. 2018-12-18 17:45:46 -06:00

ec9265aa95 arch assertions: Correct duplicated logic from commit dbf01d12b7. Checking for PID == zero is not a valid way to test for the IDLE task in all configurations! This is only true in the single CPU configuration. In multiple CPU configurations, there will be a separate IDLE task for each CPU with a different PID. 2018-12-18 17:35:42 -06:00

dbf01d12b7 Assertions: Identify the running task correctly when dumping task state information. It takes time to switch to the target task after g_readytorun has been modified. If panic/assert happen during this period, the dump will contain the incorrect and confusing information due to the difference between the real running task and the return value of this_task(). This change resolve this problem by adding g_running_task to track the real running task through the context switch. 2018-11-15 07:11:51 -06:00

bb88f8d0bb Squashed commit of the following:
A few bugfixes in initial testing on the i.MX6.  Behavior seems a little more stable, but there are still memory corruption issues.  Also print CPU number on assertion.
    Add a file missed in the last big commit.
    arch/arm/src/armv7a and imx6:  Add support for per-CPU IRQ and FIQ interrupt stacks (bugfix).  Add support so that up_assert will print the correct interrupt stack on an assertion (FIQ stack is still not printed).
    arch/arm/src/lc823450: Combine the content of smp_macros.h into chip.h.  Add support so that up_assert will print the correct interrupt stack on an assertion.

a581d7c2e3 arch/: Relasted to last big change to force interrupts to be disabled. In the SMP case, we still must call leave_critical_section() at least once in order to compensate for the fact that the irqcount was incremented in up_schedsigaction(). 2018-06-06 17:04:12 -06:00

977d41d519 Based on a change recommended by Mark Shulte:
Signal handlers maybe run with interrupts enabled or disabled, depending on how the task the received the signal was blocked. (i.e.: If sem_wait() is called, then we disable interrupts, then block the currently running task). This could be dangerous, because user code would be running with interrupts disabled.

This change forces interrupts to be enabled in up_sigdeliver() before executing the signal handler calling up_irq_enable() explicitly.  This is safe because, when we return to normal execution, interrupts will be restored to their previous state when the signal handler returns.

de6b13b3ab Per OpenGroup.org, syslog -- and, hence, nonstandard vsyslog, and debug wrappers -- does not return a value. Rename _vsyslog to nx_vsyslog. Use internal nx_vsyslog in the few cases where a return value is required. 2018-03-04 08:07:07 -06:00
