## Xanmod-ROG configuration script; this script is called during package creation and tunes kernel configuration
##            where we want to differ from upstream Xanmod

## Any user customization should be done in $PKGDIR/myconfig or $HOME/.config/linux-xanmod-rog/myconfig; if either
## of these scripts exists they'll be called during package build after this script ends

## bake in s0ix debugging parameters
scripts/config  --enable CONFIG_CMDLINE_BOOL \
                --set-str CONFIG_CMDLINE "makepkgplaceholderyolo" \
                --disable CMDLINE_OVERRIDE

## HACK: forcibly fixup CONFIG_CMDLINE here as using scripts/config mangles escaped quotes
sed -i 's#makepkgplaceholderyolo#pm_debug_messages amd_pmc.enable_stb=1 amd_pmc.dyndbg=\\"+p\\" acpi.dyndbg=\\"file drivers/acpi/x86/s2idle.c +p\\"#' .config

# note the double escaped quotes above, sed strips one; the final result in .config needs to contain
# single slash escaped quotes (eg: `CONFIG_CMDLINE="foo.dyndbg=\"+p\""`) to avoid dyndbg parse errors
# at boot. this is impossible with the current kernel config script.

## XXX: As this kernel package is primarily targeted at ASUS laptops we default to schedutil so the machine properly clocks down
