Hauke Mehrtens	9936e16b72	io: Fix printing 4 bytes memory on 64 bit systems ... On 64 bit Linux systems long is 8 bytes long, on 32 bit Linux systems it is 4 bytes long. Here we want to print 4 bytes and not 8 bytes, use int instead of long. This fixes printing 4 bytes on 64 bit systems. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>	2019-11-13 23:25:03 +01:00
Hauke Mehrtens	90df0f3e24	io: Open /dev/mem with O_SYNC for uncached access ... 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>	2019-07-24 13:57:09 +02:00
