powerpc: Restore CONFIG_DEBUG_INFO in defconfigs

2022-06-29T06:58:49Z

Commit f9b3cd245784 ("Kconfig.debug: make DEBUG_INFO selectable from a choice") broke the selection of CONFIG_DEBUG_INFO by powerpc defconfigs. It is now necessary to select one of the three DEBUG_INFO_DWARF* options to get DEBUG_INFO enabled. Replace DEBUG_INFO=y by DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT=y in all defconfigs using the following command: sed -i s/DEBUG_INFO=y/DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT=y/g `git grep -l DEBUG_INFO arch/powerpc/configs/` Fixes: f9b3cd245784 ("Kconfig.debug: make DEBUG_INFO selectable from a choice") Cc: stable@vger.kernel.org Signed-off-by: Christophe Leroy Reviewed-by: Kees Cook Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/98a4c2603bf9e4b776e219f5b8541d23aa24e854.1654930308.git.christophe.leroy@csgroup.eu

powerpc/8xx: Drop CONFIG_8xx_COPYBACK option

2020-05-26T12:22:20Z

CONFIG_8xx_COPYBACK was there to help disabling copyback cache mode for debuging hardware. But nobody will design new boards with 8xx now. All 8xx platforms select it, so make it the default and remove the option. Also remove the Mx_RESETVAL values which are pretty useless and hide the real value while reading code.

powerpc: configs: Cleanup old Kconfig options

2020-01-31T10:29:03Z

CONFIG_ENABLE_WARN_DEPRECATED is gone since commit 771c035372a0 ("deprecate the '__deprecated' attribute warnings entirely and for good"). CONFIG_IOSCHED_DEADLINE and CONFIG_IOSCHED_CFQ are gone since commit f382fb0bcef4 ("block: remove legacy IO schedulers"). The IOSCHED_DEADLINE was replaced by MQ_IOSCHED_DEADLINE and it will be now enabled by default (along with MQ_IOSCHED_KYBER).

powerpc/configs: remove obsolete CONFIG_INET_XFRM_MODE_* and CONFIG_INET6_XFRM_MODE_*

2019-11-13T05:58:06Z

These Kconfig options has been removed in commit 4c145dce2601 ("xfrm: make xfrm modes builtin") So there is no point to keep it in defconfigs any longer.

powerpc/configs: Remove useless UEVENT_HELPER_PATH

2019-07-03T05:19:36Z

Remove the CONFIG_UEVENT_HELPER_PATH because: 1. It is disabled since commit 1be01d4a5714 ("driver: base: Disable CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was made default to 'n', 2. It is not recommended (help message: "This should not be used today [...] creates a high system load") and was kept only for ancient userland, 3. Certain userland specifically requests it to be disabled (systemd README: "Legacy hotplug slows down the system and confuses udev").

powerpc: Update all configs using savedefconfig

2015-01-20T07:06:58Z

It looks like it's ~4 years since we updated some of these, so do a bulk update. Verified that the before and after generated configs are exactly the same. Which begs the question why update them? The answer is that it can be confusing when the stored defconfig drifts too far from the generated result. Signed-off-by: Michael Ellerman

powerpc 8xx: defconfig: slice by 4 is more efficient than the default slice by 8 on Powerpc 8xx.

2014-01-08T01:11:20Z

On PPC_8xx, CRC32_SLICEBY4 is more efficient (almost twice) than CRC32_SLICEBY8, as shown below: With CRC32_SLICEBY8: [ 1.109204] crc32: CRC_LE_BITS = 64, CRC_BE BITS = 64 [ 1.114401] crc32: self tests passed, processed 225944 bytes in 15118910 nsec [ 1.130655] crc32c: CRC_LE_BITS = 64 [ 1.134235] crc32c: self tests passed, processed 225944 bytes in 4479879 nsec With CRC32_SLICEBY4: [ 1.097129] crc32: CRC_LE_BITS = 32, CRC_BE BITS = 32 [ 1.101878] crc32: self tests passed, processed 225944 bytes in 8616242 nsec [ 1.116298] crc32c: CRC_LE_BITS = 32 [ 1.119607] crc32c: self tests passed, processed 225944 bytes in 3289576 nsec Signed-off-by: Christophe Leroy Signed-off-by: Scott Wood

kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT

2011-01-21T01:02:05Z

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.
