Please can you also add a devicetree binding with corresponding
documentation to enable this workaround on non-ACPI based systems too?
It should be straightforward if you update the arm_smmu_options table.
As I mentioned before, devicetree was a lower priority and we would definitely
submit patch to support that. Even if we update the arm_smmu_options table
with DT binding, the generic function to retrieve the MSI address regions only
works on ACPI/IORT case now.
Hi Will,
Can you confirm your stance on supporting this workaround for DT as well
as ACPI?
For us, we now only "officially" support ACPI FW, and DT support at this
point is patchy/limited. To me, adding DT support is just more errata
workaround code to maintain with little useful gain.
Thanks very much,
John
Moreover I am on holidays starting tomorrow, and really appreciate if this series
can go through now.
Please let me know.
Thanks,
Shameer
