lib: sbi: Add optional resume address to hart suspend

2024-12-06T03:56:35Z

Add an optional resume address to the platform specific hart suspend call. Signed-off-by: Subrahmanya Lingappa Signed-off-by: Anup Patel

lib: utils/irqchip: Move per-hart data from fdt_plic to plic

2024-11-28T06:05:01Z

The per-hart PLIC pointer is not really specific to FDT platforms. Move it into the main driver and drop the extra wrapper functions. Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

lib: utils/irqchip: plic: Common PM save/restore

2024-11-28T05:58:38Z

Move the PLIC save/restore functions inside the driver, so they can be reused on any platform that needs them. The memory needed to store the PLIC context is also allocated by the driver. The PM data cannot be completely encapsulated, as some platforms (including Allwinner D1) need to program the IRQ enable status to a sideband interrupt controller for wakeup capability.

platform: generic: Pass FDT to early/final_init overrides

2024-08-24T07:32:54Z

Several of these override functions access the FDT blob. Explicitly indicate which callbacks are allowed to modify the FDT blob by passing the parameter as a possibly-const pointer. This also reduces code size by deduplicating the call to fdt_get_address(). Signed-off-by: Samuel Holland Reviewed-by: Andrew Jones Reviewed-by: Anup Patel

platform: generic: allwinner: Optimize current hart scratch access

2024-04-05T12:04:25Z

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

platform: generic: allwinner: sun20i-d1: Remove duplicated CSR definitions

2024-03-20T05:35:13Z

All T-Head CSRs are already defined in thead/c9xx_encoding.h. Let's reuse the values from there instead of redefining them with a slightly different name. Signed-off-by: Christoph Müllner Reviewed-by: Anup Patel

platform: generic: thead: separate implement of T-HEAD c9xx pmu

2023-11-14T16:23:45Z

Separate the implement of T-HEAD c9xx pmu to allow any platform with c9xx cores can use it. Signed-off-by: Inochi Amaoto Reviewed-by: Anup Patel

platform: generic: thead: move to thead c9xx header to vendor specific postion

2023-11-14T16:23:42Z

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

platform: generic: allwinner: fix OF process for T-HEAD c9xx pmu

2023-09-10T05:34:59Z

T-HEAD c9xx pmu needs to clear OV bits of MCOUNTEROF in any condition to avoid unnecessary OF interrupts. In addition, the S-mode SCOUNTEROF only have OF bit set when the related bits of MCOUNTERWEN is set, so also configure MCOUNTERWEN to allow kernel to access valid SCOUNTEROF.

platform: generic: allwinner: correct mhpmevent count

2023-08-22T07:56:05Z

Only the CSR mhpmevent 3-9,13-17 of D1 have valid function, so change the mhpm_mask to a valid value to avoid invalid usage.
