Ah, there's already quite a lot of dependency built for this feature:(
Not really. It's only an RFC ATM, and my requirement is a sysfs file to read
the SoC id(s) (under ACPI FW). So I would still expect to be able to support
this from the SMCCC extension method.
Hi Sudeep,
As mentioned above, yes the driver would remain almost same for SMCCC
SOC_ID support too. The main point was: do we need to add support to
PPTT Type 2 entry when we know there is proposal to deprecate it. I
would at-least wait to see progress on that until I would add this to
the kernel.
Not having support in the kernel for a feature which may be officially
deprecated, i.e public knowledge, in future (maybe 1 year) seems harsh.
Especially when there is no final released alternative.
So do you know if other OSes use it?
Thanks
John
