lib: sbi: pmu: fix usage of sbi_pmu_irq_bit()

2025-01-30T05:00:45Z

While sbi_pmu_irq_bit() was used to delegate irq to S-mode, LCOFIP usage was still hardcoded in various places. This led to change the returned value of sbi_pmu_irq_bit() to be a bit number rather than a bit mask since it returns an 'int' and we need to obtain the bit number itself to handle it in the IRQs handlers. Add a similar function to return the irq mask which can also be used where the mask is required rather than the bit itself.

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 CSR encoding for t-head c9xx cores is shared across all the platforms with these cores. So move header thead_c9xx.h to the thead subdir. Signed-off-by: Inochi Amaoto Acked-by: Guo Ren Reviewed-by: Anup Patel
