lib: utils: Add MPXY RPMI mailbox driver for System MSI service group

2025-02-13T05:40:03+00:00

The supervisor software can directly receive most of the system MSIs except P2A doorbell and MSIs preferred to be handled in M-mode. Add MPXY RPMI mailbox client driver for the System MSI service group. Signed-off-by: Anup Patel

lib: utils: Split the FDT MPXY RPMI mailbox client into two parts

2025-02-13T05:40:03+00:00

Instead of having one common FDT MPXY RPMI mailbox client drivers for various RPMI service groups, split this driver into two parts: 1) Common MPXY RPMI mailbox client library 2) MPXY driver for RPMI clock service group The above split enables having a separate MPXY driver for each RPMI clock service group and #1 (above) will allow code sharing between various MPXY RPMI drivers.

lib: utils: Initialize miscellaneous drivers in one pass

2025-02-12T16:09:25+00:00

For driver subsystems that are not tightly integrated into the OpenSBI init sequence, it is not important that the drivers are initialized in any particular order. By putting all of these drivers in one array, they can all be initialized with a single pass through the devicetree. This saves about 10 ms of boot time on HiFive Unmatched.

platform: generic: thead: add Sophgo SG2044

2025-02-12T12:30:18+00:00

The Sophgo SG2044 is a new version of C920, although it supports sscofpmf, it still needs this pmu quirks its cores. Signed-off-by: Inochi Amaoto Reviewed-by: Anup Patel

lib: utils:Check that hartid is valid

2025-02-12T03:54:09+00:00

It is possible that hartid may not be sequential and it should not be validated against SBI_HARTMASK_MAX_BITS. Instead we should check the index of the hartid, hart index, against SBI_HARTMASK_MAX_BITS. Signed-off-by: Raj Vishwanathan Reviewed-by: Anup Patel

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

2025-01-30T05:00:45+00:00

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.

include: sbi: Fix compiling with C23 enabled compilers

platform: generic: Initialize console before other drivers

2024-12-21T12:51:50+00:00

Initialize serial drivers first, so messages printed by other drivers do not need to use the early console buffer. Suggested-by: Anup Patel Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

lib: utils/mpxy: Add RPMI client driver for MPXY

2024-12-06T03:56:57+00:00

Add a generic RPMI mailbox client driver which provides a MPXY channel. Initially, this driver only supports RPMI clock service group but can be extended to support multiple RPMI service groups. Signed-off-by: Rahul Pathak Co-developed-by: Anup Patel Signed-off-by: Anup Patel

lib: utils: Add simple FDT based MPXY driver framework

The generic platform can have multiple MPXY drivers so add a simple FDT based MPXY driver framework. Signed-off-by: Anup Patel
