a5ea53da - riscv: hwprobe: Add thead vendor extension probing

Thu, 14 Nov 2024 02:21:16 +0000

riscv: hwprobe: Add thead vendor extension probingAdd a new hwprobe key "RISCV_HWPROBE_KEY_VENDOR_EXT_THEAD_0" whichallows userspace to probe for the new RISCV_ISA_VENDOR_EXT_XTHEADVECTORvendor extension.This new key will allow userspace code to probe for which thead vendorextensions are supported. This API is modeled to be consistent withRISCV_HWPROBE_KEY_IMA_EXT_0. The bitmask returned will have each bitcorresponding to a supported thead vendor extension of the cpumask set.Just like RISCV_HWPROBE_KEY_IMA_EXT_0, this allows a userspace programto determine all of the supported thead vendor extensions in one call.Signed-off-by: Charlie Jenkins Reviewed-by: Evan Green Tested-by: Yangyu Chen Link: https://lore.kernel.org/r/20241113-xtheadvector-v11-10-236c22791ef9@rivosinc.comSigned-off-by: Palmer Dabbelt List of files: /linux-6.15/arch/riscv/kernel/vendor_extensions/Makefile

23c996fc - riscv: Extend cpufeature.c to detect vendor extensions

Fri, 19 Jul 2024 16:15:18 +0000

riscv: Extend cpufeature.c to detect vendor extensionsInstead of grouping all vendor extensions into the same riscv_isa_extthat standard instructions use, create a struct"riscv_isa_vendor_ext_data_list" that allows each vendor to maintaintheir vendor extensions independently of the standard extensions.xandespmu is currently the only vendor extension so that is the onlyextension that is affected by this change.An additional benefit of this is that the extensions of each vendor canbe conditionally enabled. A config RISCV_ISA_VENDOR_EXT_ANDES has beenadded to allow for that.Signed-off-by: Charlie Jenkins Reviewed-by: Conor Dooley Reviewed-by: Andy Chiu Tested-by: Yu Chien Peter Lin Reviewed-by: Yu Chien Peter Lin Link: https://lore.kernel.org/r/20240719-support_vendor_extensions-v3-1-0af7587bbec0@rivosinc.comSigned-off-by: Palmer Dabbelt List of files: /linux-6.15/arch/riscv/kernel/vendor_extensions/Makefile
