Subject: [PATCH v7 00/12] Add SiFive TMC0 and SMC0 driver
Date: Mon, 20 Oct 2025 14:34:02 +0800	[thread overview]
Message-ID: <20251020-cache-upstream-v7-0-69a132447d8a@sifive.com> (raw)

SiFive TMC0 and SMC0 are the power controllers that controls the Tile and
CoreComplex power domain. Add the drivers to support the power
management features such as HSM STOP and System Suspend.

Features such as power management may require flushing the entire
cache before entering a non-retention power state. To support this, a
simple cache flush framework is introduced to allow the external CMO
to perform a full cache flush.

---
Changes in v7:
- Update the change log of PATCH 9 and PATCH 12 because the TMC0 and SMC0 are moved to the
  lib/utils/hsm and lib/utils/suspend.
- Add new commit to Extend the sbi_ipi_raw_send() to use all available IPI device in
  PATCH 8 and use it in PATCH 9
- Add `system_resume` callback for system suspend
- Since the SMC0 driver need the `aplic_reinit_all()`, update the
  SMC0 Kconfig option to depend upon the APLIC Kconfig option
- Link to v6: https://lore.kernel.org/r/20250905-cache-upstream-v6-0-6a6da629c961@sifive.com

Changes in v6:
- Rename the aplic_restore() to aplic_reinit_all()
- Remove fdt_hsm_sifive_tmc0_cold_init() from TMC0 header file
- Remove the sifive_dev_platform.c
- Add a dummy inline flavor of fdt_cmo_init() for the case where CONFIG_FDT_CACHE is disabled
- Link to v5: https://lore.kernel.org/r/20250902-cache-upstream-v5-0-af60a067f47a@sifive.com

Changes in v5:
- Put the SiFive TMC0 driver to the fdt_early_driver
- Fix the format of the comments in SiFive TMC0 driver

Changes in v4:
- Call fdt_cmo_init() directly as part of generic_early_init()
- Rename SBI_HART_EXT_XSF* to SBI_HART_EXT_XSIFIVE*
- Move the TMC0 driver to the lib/utils/hsm/
- Move the SMC0 driver to the lib/utils/suspend/

Changes in v3:
- Add the SiFive TMC and SMC driver

Changes in v2:
- Since the platform override hooks was deprecated, use the fdt_driver
for initializing the sifive_dev_platform.
