1ac9558460 sched/irq and sched/sched: Measurement of interrupt handler duration used to be available only in Tickless mode since it used the high resolution Tickless timer to measure interrupt time. This commit adds CONFIG_SCHED_IRQMONITOR_GETTIME which, if enabled, will force the interrupt duration caculation to use the same high-resolution, platform-specific timer as is used with the Critical Section Monitor. This leads to two improvements: (1) You can now measure interrupt duration in non-Tickless mode, and (2) in either mode, the interrupt duration and the critical section measures will use the same high-resulotion timer and should, therefore, never be any descripancy due to different clock sources. 2018-11-26 11:29:20 -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.
