| * | io: Open /dev/mem with O_SYNC for uncached access | Hauke Mehrtens | 2019-07-24 |
| | | | | | | | | | | | | Only when /dev/mem is opened with O_SYNC the write and *read* is done uncached. We saw wrong values read out from the hardware without setting O_SYNC, the busybox devmem tool showed different values, when O_SYNC is also set for the io tool, it reads out the same values as devmem. When looking at the drivers/char/mem.c file in the kernel it is behaving differently based on the O_DSYNC flag. Signed-off-by: Hauke Mehrtens <hauke.mehrtens@intel.com> | ||
