Subject: Re: [PATCH v11 00/16] iommu/arm-smmu-v3: Implement Runtime/System Sleep ops
Date: Fri, 13 Nov 2026 08:37:18 +0000 [thread overview]
Message-ID: <179455903885.2418534.14656921897583011972@gmail.com> (raw)
In-Reply-To: <20260929034510.2023173-1-praan@google.com>
Hi Pranjal,
Tested the system sleep ops on RK3588 (Orange Pi 5), MMU600_PHP, no
power domain in DT, with USB3 and GMAC translated:
- s2idle x3: OK.
- deep suspend x3: the SMMU loses its state (CR0, GBPA, STRTAB_BASE
read 0 at resume); your resume path restores it, USB3 and Ethernet
work, no errors. Without it the SMMU would resume in bypass.
Not tested: runtime PM, MSI restore, CMDQV.
Tested-by: Arun Iyengar <aiyengar1990@gmail.com> # RK3588, system sleep
Arun
