platform: generic: andes: Add support for RV32 to set up PMA

2024-06-18T10:49:47Z

Like PMP, the behaviors to configure PMA will be different from RV64 and RV32. RV64 uses two Andes custom CSRs, pmacfg0 and pmacfg2, but RV32 uses four Andes custom CSRs, pmacfg0 ~ pmacfg3. This patch adds support to PMA for RV32. Signed-off-by: Ben Zong-You Xie Reviewed-by: Anup Patel

platform: generic: thead: add Canaan Kendryte K230

2024-05-09T12:40:25Z

Canaan Kendryte K230 SoC has T-Head C908 cores inside. The dt-binding has been merged into the linux kernel [1]. However, it has early version of C908 core which does not have Sscofpmf and need to use T-Head PMU extension. Thus, we add a K230 compatible string to thead_generic_match and set quirk for T-Head PMU.

platform: generic: thead: separate T-Head PMU Errata

2024-05-09T12:39:05Z

As Guo Ren said from the kernel mailing list [1], future T-Head CPUs, including the newer versions of T-Head C908, will feature standard Sscofpmf extension. For these CPUs, T-Head's implementation of PMU Overflow Interrupts may not needed anymore. In this case, we shouldn't apply T-Head PMU for all T-Head CPUs. Thus, this patch separated T-Head PMU errata. [1] https://lore.kernel.org/linux-riscv/Zh9sUUUT09LZb0MO@gmail.com/ Signed-off-by: Yangyu Chen Reviewed-by: Inochi Amaoto Reviewed-by: Anup Patel

The address of the local scratch area is stored in each hart's mscratch CSR. It is more efficient to read the CSR than to compute the address from the hart ID. Signed-off-by: Samuel Holland Reviewed-by: Anup Patel
