[1/3] firmware: arm_ffa: Skip creation of the notification bitmaps https://git.kernel.org/sudeep.holla/c/2b9c66d1abac [2/3] firmware: arm_ffa: Refactor SRI handling in prepartion to add NPI support https://git.kernel.org/sudeep.holla/c/f936c242553f [3/3] firmware: arm_ffa: Add support for handling notification pending interrupt(NPI) https://git.kernel.org/sudeep.holla/c/08530a2aa921 -- Regards, Sudeep
Add support for running the driver inside a guest/VM under a hypervisor. The main difference include: 1. supporting introducing notification pending interrupt and 2. Avoiding creation of all the notification bitmaps as they must be created by the hypervisor before the VM is initialised The guest may need to use a notification pending interrupt instead of or in addition to the schedule receiver interrupt. Signed-off-by: Sudeep Holla <sudeep.holla@arm.com> --- Hi Jens, This is almost identical to you single patch now. Just split into 3 patches with refactoring kept separate. Can you please check if this continues to work on your setup(unlikely to break anything). Once you confirm, I am happy to queue it. Regards, Sudeep Changes in v2: - Dropped the idea of SRI or NPI support - Added back both SRI and NPI to co-exist as in the original patch from Jens https://lore.kernel.org/all/20240325081335.2326979-1-jens.wiklander@linaro.org/ - Link to v1: https://lore.kernel.org/r/20240410-ffa_npi_support-v1-0-1a5223391bd1@arm.com --- Jens Wiklander (2): firmware: arm_ffa: Skip creation of the notification bitmaps firmware: arm_ffa: Add support for handling notification pending interrupt(NPI) Sudeep Holla (1): firmware: arm_ffa: Refactor SRI handling in prepartion to add NPI support drivers/firmware/arm_ffa/driver.c | 128 ++++++++++++++++++++++++++------------ 1 file changed, 87 insertions(+), 41 deletions(-) --- base-commit: 2c71fdf02a95b3dd425b42f28fd47fb2b1d22702 change-id: 20240410-ffa_npi_support-98edfdcc4882 Best regards,
