Based on the following commit from the Renesas BSP:
7003b9f732cffdc778fceb4bffb05ebb4540f726
located at:
https://github.com/renesas-rcar/linux-bsp/tree/v5.10.41/rcar-5.1.3.rc5
I would like to reuse an upstream-based patch instead of this BSP patch.
Makes sense
Linux upstream doesn't support the IPMMU-VMSA driver for R-Car S4 yet,
but I believe the following patch can be helpful for R-Car S4:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/iommu/ipmmu-vmsa.c?h=v5.16-rc1&id=7a62ced8ebd0e1b692c9dc4781a8d4ddb0f74792
I have a plan to modify the Linux IPMMU-VMSA driver for R-Car S4 in the future.
- The ipmmu_features_r8a779a0 is replaced with ipmmu_features_rcar_gen4.
Thank you for the pointer, I got it, will do.
I'll review further patches (8/10 through 10/10) tomorrow or later.
Thank you!
Best regards,
Yoshihiro Shimoda
