348a03287d arch/arm: The last big change that unified the cache interfaces had a bad side-effect: It also removed the memory barrier definitions that were also in the removed architecture-specific cache.h header files.

641a98a434 arch/: The saved return register state is available on the user stack. Thic commit reorders some logic so that certain, critical registers are preserved in the TCB. This does not make the logic 100% secure, but does prevent some obvious things. sched/signal/sig_delivery: Add a flag to the TCB to indicate that we are in a signal handler. Use this flag to assure that a there a never attempts to nest signal handling operations on a thread. This was guaranteed before but when locking of pre-emption during signal delivering was eliminated in a previous commit, there was a remote possibility of an attempt to do nested signal handling. This flag assures that there is only one signal handled at a time. 2019-02-03 15:29:47 -06:00

b4f488e8bf Revert "arch/arm/armv7-m: MPU: mpu_log2regionceil needs take into account the offset too" 
Masayuki Ishikawa reports that this commit breaks ALL PROTECTED mode builds.

It violates the basic requirements of the use of the MPU in protected mode.  Those basic requirements are:

1. The MPU region must be aligned to the base address of the memory region being mapped (it may NEVER extend before the memory region).  That is, the following MUST always be zero:

   (base & ((1 << l2size) - 1))

2. The MPU region must never extend beyond the end of the memory region.  That is, the following must be true:

   size >= (1 << l2size)

This reverts commit 8b63d02309.

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.

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!

df2241f816 This commit changes the lazy and non-lazy exception handler to remove a couple of cpsid instructions from them on ARMv7-m. If my understanding is correct then these interrupt manipulations aren't doing anything anyway because prioritization stops secondary interrupts arriving and, even if they did work, they would have introduced race conditions for the period of time between the interrupt arriving and further interrupts being disabled. 2018-12-06 07:20:21 -06:00

d0cda60442 In the current implementation we only use very high priority interrupts (levels 0, 0x10 and 0x20 in CORTEX-M speak) but that means there are loads of lower priority ones that are effectively unused. I have *not* changed the semantics of these levels but have 'shifted' them to be based around the midpoint of the available interrupts (0x80) rather than at the top end....that allows for interrupts to be defined above (or, indeed, below) them as needed by the application. This should have no functional effect on existing code but adds in a clean capability to define higher priority interrupts. 2018-12-03 17:41:59 -06:00

c6851201c0 This commit adds a new function arch_invalidate_dcache_by_addr(). It takes the same parameters as arch_invalidate_dcache(), but performs invalidation of only the lines in cache that need to be invalidated. This new function could be used as a a direct replacement for arch_invalidate_dcache(). 
The user of this invalidation are mmcsd_sdio currently.  The mmcsd_sdio driver makes calls for dcache invalidation through the chip specific architecture function SDIO_DMARECVSETUP(). I changed the arch/arm/stm32f7 chips to use arch_invalidate_dcache_by_addr() instead of arch_invalidate_dcache().

This commit includes additional changes to mmcsd_sdio.c.  I created SDIO_DMADELYDINVLDT() (DMA delayed invalidate) to invalidate store-into mode dcaches after the DMA transfer.  I have been using SDIO_DMADELYDINVLDT() for several weeks now and it has fixed the problems that I previously reported regarding non-cache aligned buffer invalidation errors (for my store-through dcache). However, it does not permit use of unaligned DMA buffers for store-into mode dcaches.

SDIO_DMADELYDINVLDT() is a NoOp unless the chip specific Kconfig file selects CONFIG_ARCH_HAVE_SDIO_DELAYED_INVLDT. I have modified all the stm32f7 chips to select it.

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

09ccd43d61 arch/arm/include/armv7-m, arch/arm/include/armv7-m, arch/arm/include/stm32f7: Add a configuration to enable workaround for r0p1 Errata 837070: Increasing priority usingwrite to BASEPRI does not take effect immediately. 
This update is required to be serialized to the instruction stream meaning that after this update completes, it takes effect immediately and no exceptions of lower priority than the new boosted priority can pre-empt execution.  Because of this erratum, the priority boosting does not take place immediately, allowing the instruction after the MSR to be interrupted by an exception of lower priority than the new boosted priority. This effect is only limited to the next instruction. Subsequent instructions are guaranteed to see the new boosted priority.

This was raised in Bitbucket issue 113 from Vadzim Dambrouski.

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
Gregory Nutt
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.

3a0413c048 Back out most of 34be3e7c3c and update README again. Windows native tools cannot be used with Ubuntu under Windows 10 now. For Cygwin, that support depends on the 'cygpath -w' tool to convert POSIX paths to Windows paths. There is no corresponding tool for Ubuntu under Windows 10. 2017-01-01 16:29:03 -06:00

39183d37b8 Change all time conversions. Yech. New timer units in microseconds breaks all existing logic that used milliseconds in the conversions. Something likely got broken doing this, probably because I confused a MSEC2TICK conversion with a TICK2MSEC conversion. Also, the tickless OS no appears fully functional and passes the OS test on the simulator with no errors 2014-08-07 18:00:38 -06:00
