I want to apply one patch which is machine specific(old-silicon) from my custom meta layer, for that I defined MACHINEOVERRIDES in my meta-dcu/conf/machine/old_silicon.conf
MACHINEOVERRIDES =. "old_silicon:"
Then I applied my patch in meta-dcu/recipes-rzg2l/recipes-bsp/trusted-firmware-a/trusted-firmware-a.bbappend
SRC_URI_old_silicon += "file://0002-trusted-firmware-a-add-rd-wr-64-bit-reg-workaround.patch"
But I am getting error:
ERROR: trusted-firmware-a-v2.6+git-r0 do_patch: Applying patch '0002-trusted-firmware-a-add-rd-wr-64-bit-reg-workaround.patch' on target directory '/build/tmp/work/old_silicon-poky-linux/trusted-firmware-a/v2.6+git-r0/git' Command Error: 'quilt --quiltrc /build/tmp/work/old_silicon-poky-linux/trusted-firmware-a/v2.6+git-r0/recipe-sysroot-native/etc/quiltrc push' exited with 0 Output: Applying patch 0002-trusted-firmware-a-add-rd-wr-64-bit-reg-workaround.patch can't find file to patch at input line 5 Perhaps you used the wrong -p or --strip option? The text leading up to this was: No file to patch. Skipping patch. 6 out of 6 hunks ignored patch unexpectedly ends in middle of line
You added the patch properly (otherwise bitbake would've complained that the patch didnt exist), I'd still recommend you switch to the append syntax to avoid errors:
SRC_URI_append_old_sillicon = " file://0002-trusted-firmware-a-add-rd-wr-64-bit-reg-workaround.patch"
Your error is that your patch is being applied, however when quilt is applying your patch it can't find the file that its supposed to be modified (presumably gicv3_private.h).
Typically the file does exist and youre just trying to apply it in the wrong directory or something, hence why bitbake is suggesting to use the -p or --strip options for quilt, this would be the case if for example:
The patch is trying to modify
drivers/arm/gic/v3/gicv3_private.h
but the file is actually at
src/drivers/arm/gic/v3/gicv3_private.h
(or something similar)
Take a look at striplevel and patchdir in SRC_URI, setting these properly is probably what you want.
