| * ARM: 8833/1: Ensure that NEON code always compiles with ClangNathan Chancellor2019-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit de9c0d49d85dc563549972edc5589d195cd5e859 ] While building arm32 allyesconfig, I ran into the following errors: arch/arm/lib/xor-neon.c:17:2: error: You should compile this file with '-mfloat-abi=softfp -mfpu=neon' In file included from lib/raid6/neon1.c:27: /home/nathan/cbl/prebuilt/lib/clang/8.0.0/include/arm_neon.h:28:2: error: "NEON support not enabled" Building V=1 showed NEON_FLAGS getting passed along to Clang but __ARM_NEON__ was not getting defined. Ultimately, it boils down to Clang only defining __ARM_NEON__ when targeting armv7, rather than armv6k, which is the '-march' value for allyesconfig. >From lib/Basic/Targets/ARM.cpp in the Clang source: // This only gets set when Neon instructions are actually available, unlike // the VFP define, hence the soft float and arch check. This is subtly // different from gcc, we follow the intent which was that it should be set // when Neon instructions are actually available. if ((FPU & NeonFPU) && !SoftFloat && ArchVersion >= 7) { Builder.defineMacro("__ARM_NEON", "1"); Builder.defineMacro("__ARM_NEON__"); // current AArch32 NEON implementations do not support double-precision // floating-point even when it is present in VFP. Builder.defineMacro("__ARM_NEON_FP", "0x" + Twine::utohexstr(HW_FP & ~HW_FP_DP)); } Ard Biesheuvel recommended explicitly adding '-march=armv7-a' at the beginning of the NEON_FLAGS definitions so that __ARM_NEON__ always gets definined by Clang. This doesn't functionally change anything because that code will only run where NEON is supported, which is implicitly armv7.

| | | | | | | | | | | | | | | | | | | | | | | | | | bootargs Currently kernel crash randomly when K2L EVM is booted without clk_ignore_unused in the bootargs. This workaround is not needed on other K2 devices such as K2HK and K2E and with this fix, we can remove the workaround altogether. netcp driver on K2L uses linked ram on OSR (On chip Static RAM) and requires the clock to this peripheral enabled for proper functioning. This is the reason for the kernel crash. So add the clock node to fix this issue. While at it, remove the workaround documentation as well. With the fix applied, clk_summary dump shows the clock to OSR enabled. cat /sys/kernel/debug/clk/clk_summary ------cut-------------- tcp3d-1 0 0 399360000 0 0 tcp3d-0 0 0 399360000 0 0 osr 1 1 399360000 0 0 fftc-0 0 0 399360000 0 0 -----cut---------------- Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Santosh Shilimkar <ssantosh@kernel.org>

Bootloaders on Exynos542x-based boards often use the register PMU_SPARE2 (0x908) in the same way as on Exynos3250: as a indicator the secondary CPU was booted on. The bootloader will set this value to non-zero, after sucessfull power up of secondary CPU. In the same time this booted CPU will stuck (spin) waiting for software reset. 2. Exynos542x entry address for secondary CPU boot up after system suspend (with MCPM enabled and in non-secure mode). See arch/arm/mach-exynos/mcpm-exynos.c for source code.

This is not scalable as user has to change the DTS if they need upgrade to a new firmware. Instead, add the firmware file name in the driver itself. As long as there is no API change, new firmware upgrade is easy and require no driver change. User is expected to copy the firmware image to the file system and add a sym link to the new firmware for doing an upgrade. Driver add a array of firmware file names to search for the available firmware blobs. This scheme also prepare the driver for future changes to API if ever happens. In such case it is assumed that driver needs to change to accommodate the new firmware and new firmware file name will get added to the array. Also update the DT document to remove the firmware attribute and add description about firmware in the driver documentation.

This became unused with commit e9da6e9905e6, confirmed with commit 64d3b6a3f480. We also have a 8MB guard area before the vmalloc area. With the default 240MB vmalloc area size and the current VMALLOC_END definition, that means the end of low memory ends up at 0xef800000 which is unfortunate for 768MB machines where 8MB of RAM is lost to himem. Let's move VMALLOC_END to 0xff800000 so the guard area won't chop the top of the 768MB low memory area while keeping the default vmalloc area size unchanged and still preserving a gap between the vmalloc and fixmap areas.

This patch provides a single CPU mask, making it possible to run "-a" perf session (previously it would request the same CCN event, for example cycle counter, on each available core and most likely fail). Initially the mask is set to the CPU that happened to probe the driver, but it will be changed when it is hot-un-plugged (active events are migrated to another CPU then). Example: Performance counter stats for 'system wide': CPU0 2968148 cycles CPU1 2236736 cycles CPU2 1797968 cycles CPU3 1831715 cycles CPU1 1201850868 ccn/cycles/ 1.001241383 seconds time elapsed Signed-off-by: Pawel Moll <pawel.moll@arm.com>

* | Documentation: ARM: EXYNOS: Describe boot loaders interfaceKrzysztof Kozlowski2015-06-08
|/ | | | | | | | | | | | | | | | Various boot loaders for Exynos based boards use certain memory addresses during booting for different purposes. Mostly this is one of following : 1. as a CPU boot address, 2. for storing magic cookie related to low power mode (AFTR, sleep). The document, based solely on kernel source code, tries to group the information scattered over different files. This would help in the future when adding support for new SoC or when extending features related to low power modes.
