[PATCH 0/2] Make cppc acpi driver aware of pcc subspace ids

[George Cherian]

The current cppc acpi driver works with only one pcc subspace id.
It maintains and registers only one pcc channel even if the acpi table has 
different pcc subspace ids. The series tries to address the same by making 
cppc acpi driver aware of multiple possible pcc subspace ids.

Patch 1 : In preparation to share the MAX_PCC_SUBSPACE definition with cppc acpi
	  driver
Patch 2 : Make the cppc acpi driver aware of multiple pcc subspace ids.

[PATCH 1/2] mailbox: PCC: Move the MAX_PCC_SUBSPACES definition to header file

[George Cherian]

Move the MAX_PCC_SUBSPACES definition to acpi/pcc.h file. In preparation to
add subspace id support for cppc_acpi driver.

[PATCH 2/2] ACPI / CPPC: Make cppc acpi driver aware of pcc subspace ids

[George Cherian]

Based on Section 14.1 of ACPI specification, it is possible to have a
maximum of 256 PCC subspace ids. Add support of multiple PCC subspace id
instead of using a single global pcc_data structure.

While at that fix the time_delta check in send_pcc_cmd() so that last_mpar_reset
and mpar_count is initialized properly. Also maintain a global total_mpar_count
which is a sum of per subspace id mpar value.

Could you please provide clarification on why sum of total_mpar_count is
required? Do you assume that there always will be only one single firmware CPU
that handles PCC commands on another side?

Theoretically different PCC channels can be connected to different platform CPUs
on other end (imagine NUMA systems in case of CPPC) so it's not clear why transport
layer of PCC should use that global count. Also, ACPI spec 6.1 (page 701) in
in description of MPAR states "The maximum number of periodic requests that the subspace
channel can support".

I don't like the direction of where it's going.

To send commands through PCC channel you don't need to know CPU number.
Ideally, send_pcc_cmd() shouldn't care a lot about software entity that uses
it (CPPC, RASF, MPST, etc) and passing some CPU number to this function you
bind it to CPPC interfaces while it shouldn't depend on it.
Maybe you can pass subspace it here instead.

BTW, is it possible to make separate mailbox PCC client and move it out from
CPPC code?

Yes you are right the total_mpar_count  should be removed and should be 
handled per subspace id. Moreover the current logic of not sending the 
command to PCC and returning with -EIO is also flawed. It should 
actually have a retry mechanism instead of returning -EIO even without 
submitting the request to the channel.

Actually if you look inside send_pcc_cmd it does a mapping of cpu to 
subspace id.  To avoid confusion it is better to pass the subspace id to 
this function than the cpu number.

Why do you think it is necessary? Currently CPPC driver itself is the 
client for mailbox/pcc driver.

That sounds interesting.
How many times should the code try to resend before giving up (let's
say that timing constraints allow the caller to resend command)?

Regarding error codes, the code can differentiate between timeout,
platform error, timing constraints (-EBUSY?), maybe some other errors.
In some cases and since mailbox framework can't resend pcc commands on
itself then it's the client responsibility to re-queue a command.

That is what I tried to suggest in my comments.

There is no reason to copy-paste client code.

I didn't find if it's allowed by ACPI spec for few entities as MPST and
CPPC to use the same PCC channel for example but if yes, then separate
client code should care about queuing, locking, re-trying.

The current ACPI 6.1 spec restricts the CPPC to a single PCC subspace. See section:
8.4.7.1.9 Using PCC Registers, which states "If the PCC register space is used, all PCC
registers must be defined to be in the same subspace."

Agreed with Prashanth, beside of that, spec also says "To amortize the
cost of PCC transactions, OSPM should read or
write all PCC registers via a single read or write command when possible."

Yes indeed the spec says so but it was not at all a scalable solution 
when platform has more number of CPU's and CPU domains. That is why we 
took this approach.

[PATCH 0/2] Make cppc acpi driver aware of pcc subspace ids

[George Cherian]

The current cppc acpi driver works with only one pcc subspace id.
It maintains and registers only one pcc channel even if the acpi table has 
different pcc subspace ids. 

As per ACPI 6.2 spec  all PCC registers, for all processors in the same 
performance domain (as defined by _PSD), must be defined to be in the same
subspace. The series tries to address the same by making cppc acpi driver 
aware of multiple possible pcc subspace ids.

Patch 1 : In preparation to share the MAX_PCC_SUBSPACE definition with cppc acpi
          driver
Patch 2 : Make the cppc acpi driver aware of multiple pcc subspace ids.

[PATCH 2/2] ACPI / CPPC: Make cppc acpi driver aware of pcc subspace ids

[George Cherian]

Based on ACPI 6.2 Section 8.4.7.1.9 If the PCC register space is used,
all PCC registers, for all processors in the same performance
domain (as defined by _PSD), must be defined to be in the same subspace.
Based on Section 14.1 of ACPI specification, it is possible to have a
maximum of 256 PCC subspace ids. Add support of multiple PCC subspace id
instead of using a single global pcc_data structure.

While at that fix the time_delta check in send_pcc_cmd() so that last_mpar_reset
and mpar_count is initialized properly.

It is unlikely we will end up using all 256 PCC subspaces, so can we
please make it a an array(size=MAX_PCC_SUBSPACES) of cppc_pcc_data
pointers. We can dynamically allocate the cppc_pcc_data structures and
maintain their references in this array.

Since we had only one PCC channel until ACPI6.1, it was ok to maintain
these (mpar_count, last_cmd_cmpl_time, last_mpar_reset) here as static
variables.
Now that we are supporting multiple PCC subspaces these should be
maintained per PCC subspaces. Can you please move these over to the
cppc_pcc_data?

The above mpar and mrtt checks should be modified to use per subspace variables.

I don't see a need for pcc_subspace_idx to be in struct cppc_pcc_data
anymore.  If you agree, may be we can remove it.

Looks like we assume a PCC subspace is always present and looking at the
6.2 spec it doesn't look like a mandatory requirement. So, the correct check
here should be:
if (pcc_subspace_id is valid && !pcc_data[pcc_subspace_id].pcc_channel_acquired)

We need to make sure pcc_subspace_id is set to an invalid value until we find a valid
PCC subspace within the _CPC package. You can correct this in next version or I can
submit a small patch.

When you send the next version with updates, can you please add a version
to the patches ex: [PATCH v2 2/2]? I think this series is v2, as it addresses some
of Alexey's  comments on the initial version.

Not only Alexey's comments, Initially this approach was rejected due to 
the ACPI spec(6.1) limitations.

Now that the spec changes for multiple subspaces are adapted I thought 
of reseting the patch version to v1. Going forward I will maintain the 
versions.
