* kbuild: drop support for CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3Nick Desaulniers2022-07-271-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The difference in most compilers between `-O3` and `-O2` is mostly down to whether loops with statically determinable trip counts are fully unrolled vs unrolled to a multiple of SIMD width. This patch is effectively a revert of commit 15f5db60a137 ("kbuild,arc: add CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3 for ARC") without re-adding ARCH_CFLAGS Ever since commit cfdbc2e16e65 ("ARC: Build system: Makefiles, Kconfig, Linker script") ARC has been built with -O3, though the reason for doing so was not specified in inline comments or the commit message. This commit does not re-add -O3 to arch/arc/Makefile. Folks looking to experiment with `-O3` (or any compiler flag for that matter) may pass them along to the command line invocation of make: $ make KCFLAGS=-O3 Code that looks to re-add an explicit Kconfig option for `-O3` should provide: 1. A rigorous and reproducible performance profile of a reasonable userspace workload that demonstrates a hot loop in the kernel that would benefit from `-O3` over `-O2`. 2. Disassembly of said loop body before and after. 3. Provides stats on terms of increase in file size.

* kbuild,arc: add CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3 for ARCMasahiro Yamada2019-09-041-0/+1
| | | | | | | | | | | | | | | | | arch/arc/Makefile overrides -O2 with -O3. This is the only user of ARCH_CFLAGS. There is no user of ARCH_CPPFLAGS or ARCH_AFLAGS. My plan is to remove ARCH_{CPP,A,C}FLAGS after refactoring the ARC Makefile. Currently, ARC has no way to enable -Wmaybe-uninitialized because both -O3 and -Os disable it. Enabling it will be useful for compile-testing. This commit allows allmodconfig (, which defaults to -O2) to enable it. Add CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3=y to all the defconfig files in arch/arc/configs/ in order to keep the current config settings.

* block: remove CONFIG_LBDAFChristoph Hellwig2019-04-061-1/+0
| | | | | | | | | | | | | | | | Currently support for 64-bit sector_t and blkcnt_t is optional on 32-bit architectures. These types are required to support block device and/or file sizes larger than 2 TiB, and have generally defaulted to on for a long time. Enabling the option only increases the i386 tinyconfig size by 145 bytes, and many data structures already always use 64-bit values for their in-core and on-disk data structures anyway, so there should not be a large change in dynamic memory usage either. Dropping this option removes a somewhat weird non-default config that has cause various bugs or compiler warnings when actually used.

* configs: get rid of obsolete CONFIG_ENABLE_WARN_DEPRECATEDAlexey Brodkin2019-03-071-1/+0
| | | | | | | | | | | | | | | | This Kconfig option was removed during v4.19 development in commit 771c035372a0 ("deprecate the '__deprecated' attribute warnings entirely and for good") so there's no point to keep it in defconfigs any longer.

* ARC: change defconfig defaults to ARCv2Kevin Hilman2018-11-301-0/+1
| | | | | | | | | | | | | | | | | | | Change the default defconfig (used with 'make defconfig') to the ARCv2 nsim_hs_defconfig, and also switch the default Kconfig ISA selection to ARCv2. This allows several default defconfigs (e.g. make defconfig, make allnoconfig, make tinyconfig) to all work with ARCv2 by default. Note since we change default architecture from ARCompact to ARCv2 it's required to explicitly mention architecture type in ARCompact defconfigs otherwise ARCv2 will be implied and binaries will be generated for ARCv2.

* arc: [devboards] Add support of NFSv3 ACLAlexey Brodkin2018-11-211-0/+1
| | | | | | | | | | | | | | By default NFSv3 doesn't support ACL (Access Control Lists) which might be quite convenient to have so that mounted NFS behaves exactly as any other local file-system. In particular missing support of ACL makes umask useless. This among other thigs fixes Glibc's "nptl/tst-umask1".

* ARC: configs: Remove CONFIG_INITRAMFS_SOURCE from defconfigsAlexey Brodkin2018-07-091-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | We used to have pre-set CONFIG_INITRAMFS_SOURCE with local path to intramfs in ARC defconfigs. This was quite convenient for in-house development but not that convenient for newcomers who obviusly don't have folders like "arc_initramfs" next to the Linux source tree. Which leads to quite surprising failure of defconfig building: ------------------------------->8----------------------------- ../scripts/gen_initramfs_list.sh: Cannot open '../../arc_initramfs_hs/' ../usr/Makefile:57: recipe for target 'usr/initramfs_data.cpio.gz' failed make[2]: *** [usr/initramfs_data.cpio.gz] Error 1 ------------------------------->8----------------------------- So now when more and more people start to deal with our defconfigs let's make their life easier with removal of CONFIG_INITRAMFS_SOURCE.

* ARC: Enable PERF_EVENTS in nSIM driven platformsAlexey Brodkin2016-10-311-0/+1
| | | | | | | | | | | | | | | | | | | Now when we have properly working performance counters in nSIM even with interrupt support (fix should be a part of upcoming nSIM engineering build 2016.12-005) we may enable perf support by default for all platforms that use nSIM for ARC cores simulation. Note 1: PCT node was missing for some reason in nsimosci.dts while all other nSIM-related .dts files already had PCT node for quite some time, so adding it now. Note 2: All defconfigs were regenerated with "make savedefconfig" which led to some clean-ups in nsimosci_hs_smp_defconfig: CONFIG_FRAMEBUFFER_CONSOLE=y was removed because it is automatically selected now by DRM.

* arc: get rid of DEVTMPFS dependency on INITRAMFS_SOURCEAlexey Brodkin2016-02-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Even though DEVTMPFS is required when our pre-built initramfs is used it is not the case in general. It is perfectly possible to use initramfs with device nodes already populated or there could be other usages, see discussion below for more detials: http://thread.gmane.org/gmane.comp.embedded.openwrt.devel/37819/focus=37821 This change removes mentioned dependency from arch/arc/Kconfig updating instead those defconfigs that are usually used with this kind of pre-build initramfs. And while at it all touched defconfigs were regenerated via savedefconfig and some options were removed: * USB is selected by other options implicitly * VGA_CONSOLE is disableb for ARC since 031e29b5877f31676739dc2f847d04c2c0732034 * EXT3_FS automatically selects EXT4_FS * MTDxxx and JFFS2_FS make no sense for AXS because AXS NAND controller is not upstreamed * NET_OSCI_LAN is not in upstream as well * ARCPGU_xxx options make no sense because ARC PGU is not yet in upstream and when it gets there all config options would be taken from devicetree Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
