Palmer Dabbelt 952b64d666 Merge patch series "Fix RISC-V toolchain extension support detection" ... Conor Dooley <conor@kernel.org> says: From: Conor Dooley <conor.dooley@microchip.com> This came up due to a report from Kevin @ kernel-ci, who had been running a mixed configuration of GNU binutils and clang. Their compiler was relatively recent & supports Zicbom but binutils @ 2.35.2 did not. Our current checks for extension support only cover the compiler, but it appears to me that we need to check both the compiler & linker support in case of "pot-luck" configurations that mix different versions of LD,AS,CC etc. Linker support does not seem possible to actually check, since the ISA string is emitted into the object files - so I put in version checks for that. The checks have gotten a bit ugly since 32 & 64 bit support need to be checked independently but ahh well. As I was going, I fell into the trap of there being duplicated checks for CC support in both the Makefile and Kconfig, so as part of renaming the Kconfig symbol to TOOLCHAIN_HAS_FOO, I dropped the extra checks in the Makefile. This has the added advantage of the TOOLCHAIN_HAS_FOO symbol for Zihintpause appearing in .config. I pushed out a version of this that specificly checked for assember support for LKP to test & it looked /okay/ - but I did some more testing today and realised that this is redudant & have since dropped the as check. I tested locally with a fair few different combinations, to try and cover each of AS, LD, CC missing support for the extension. * b4-shazam-merge: riscv: fix detection of toolchain Zihintpause support riscv: fix detection of toolchain Zicbom support Link: https://lore.kernel.org/r/20221006173520.1785507-1-conor@kernel.org Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>		2022-10-27 15:14:07 -07:00
