* powerpc 8xx: defconfig: slice by 4 is more efficient than the default slice ↵LEROY Christophe2014-01-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | by 8 on Powerpc 8xx. 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 <christophe.leroy@c-s.fr> Signed-off-by: Scott Wood <scottwood@freescale.com>
* kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes2011-01-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | This updates all the defconfigs in arch/powerpc/configs except iseries and ps3, which were updated by the preceding commits. This mostly takes the defaults, except that I turned on tickless idle and high-resolution timers for everything, and turned off instrumentation support and "Fair group CPU scheduler" for the smaller/embedded platforms.
