This series includes the code changes to get CAGF, RC State and C6
Residency of MTL.
v3: Included "Use GEN12 RPSTAT register" patch
v4:
- Rebased
- Dropped "Use GEN12 RPSTAT register" patch from this series
going to send separate series for it
v5:
- Included "drm/i915/gt: Change RC6 residency functions to accept register
ID's" based on code review feedback
v6:
- Addressed Jani N's review comments on "drm/i915/gt: Change RC6 residency
functions to accept register ID's"
- Re-add "drm/i915: Use GEN12_RPSTAT register for GT freq" to this series
v7: Rebuild, identical to v6
v8:
- Add "drm/i915/rps: Prefer REG_FIELD_GET in intel_rps_get_cagf" to the series
(based on Rodrigo's review) to consistently use REG_FIELD_GET
- Minor changes to other patches, please see individual patches for changelogs
Ashutosh Dixit (2):
drm/i915/rps: Prefer REG_FIELD_GET in intel_rps_get_cagf
drm/i915/gt: Use RC6 residency types as arguments to residency
functions
Badal Nilawar (2):
drm/i915/mtl: Modify CAGF functions for MTL
drm/i915/mtl: C6 residency and C state type for MTL SAMedia
Don Hiatt (1):
drm/i915: Use GEN12_RPSTAT register for GT freq

Instead of masks/shifts settle on REG_FIELD_GET as the standard way to
extract reg fields. This allows future patches touching this code to also
consistently use REG_FIELD_GET and friends.

* [Intel-gfx] [PATCH 2/5] drm/i915: Use GEN12_RPSTAT register for GT freq

To: intel-gfx; +Cc: dri-devel, Rodrigo Vivi
From: Don Hiatt <don.hiatt@intel.com>
On GEN12+ use GEN12_RPSTAT register to get actual resolved GT
freq. GEN12_RPSTAT does not require a forcewake and will return 0 freq if
GT is in RC6.
v2:
- Fixed review comments(Ashutosh)
- Added function intel_rps_read_rpstat_fw to read RPSTAT without
forcewake, required especially for GEN6_RPSTAT1 (Ashutosh, Tvrtko)
v3:
- Updated commit title and message for more clarity (Ashutosh)
- Replaced intel_rps_read_rpstat with direct read to GEN12_RPSTAT1 in
read_cagf (Ashutosh)
v4: Remove GEN12_CAGF_SHIFT and use REG_FIELD_GET (Rodrigo)

* [PATCH 4/5] drm/i915/gt: Use RC6 residency types as arguments to residency functions
2022-10-19 23:37 ` [Intel-gfx] " Ashutosh Dixit

To: intel-gfx; +Cc: Anshuman Gupta, Badal Nilawar, dri-devel, Rodrigo Vivi
Previously RC6 residency functions directly accepted RC6 residency register
MMIO offsets (there are four RC6 residency registers). This worked but
required an assumption on the residency register layout so was not future
proof.
Therefore change RC6 residency functions to accept RC6 residency types
instead of register MMIO offsets. The knowledge of register offsets as well
as ID to offset mapping is now maintained solely in intel_rc6 and can be
tailored for different platforms and different register layouts as need
arises.
v2: Address review comments by Jani N
- Change residency functions to accept RC6 residency types instead of
register ID's
- s/intel_rc6_print_rc5_res/intel_rc6_print_residency/
- Remove "const enum" in function arguments

^ permalink raw reply related [flat|nested] 33+ messages in thread* [Intel-gfx] [PATCH 4/5] drm/i915/gt: Use RC6 residency types as arguments to residency functions
@ 2022-10-19 23:37 ` Ashutosh Dixit
0 siblings, 0 replies; 33+ messages in thread
From: Ashutosh Dixit @ 2022-10-19 23:37 UTC (permalink / raw)
To: intel-gfx; +Cc: dri-devel, Rodrigo Vivi
Previously RC6 residency functions directly accepted RC6 residency register
MMIO offsets (there are four RC6 residency registers). This worked but
required an assumption on the residency register layout so was not future
proof.
Therefore change RC6 residency functions to accept RC6 residency types
instead of register MMIO offsets. The knowledge of register offsets as well
as ID to offset mapping is now maintained solely in intel_rc6 and can be
tailored for different platforms and different register layouts as need
arises.
v2: Address review comments by Jani N
- Change residency functions to accept RC6 residency types instead of
register ID's
- s/intel_rc6_print_rc5_res/intel_rc6_print_residency/
- Remove "const enum" in function arguments
- Naming: intel_rc6_* for enum
- Use INTEL_RC6_RES_MAX and other minor changes
v3: Don't include intel_rc6_types.h in intel_rc6.h (Jani)

I believe this patch deserves a slip between the actual support and
the debugfs, but I'm late to the review, so feel free to ignore this
comment...
but I do have more dummy doubts below:

(Just a "loud" thought here in this chunck, but no actual action requested)
should we really use "R" (Render) for this Media C state?
But well, MC6 seems to be a totally different thing and CC6 is
really strange because the C stands for Core and this can get
very confusing with the SoC or CPU C states... :(
At least with the Render we know which level of the IP we
are looking at when looking at media...

maybe "*C0" instead of "on"?

maybe use a MISSING_CASE() here?

I believe this patch deserves a slip between the actual support and
the debugfs, but I'm late to the review, so feel free to ignore this
comment...
but I do have more dummy doubts below:

(Just a "loud" thought here in this chunck, but no actual action requested)
should we really use "R" (Render) for this Media C state?
But well, MC6 seems to be a totally different thing and CC6 is
really strange because the C stands for Core and this can get
very confusing with the SoC or CPU C states... :(
At least with the Render we know which level of the IP we
are looking at when looking at media...

This function is called for both render and media gt's. But let's think
about this. We can call easily call them e.g. RC6 for render and MC6 for
media too if that is more accurate and descriptive. On the other hand, do
we really need to introduce a new term like MC6? Maybe we just stick to
RC/RC6 terminology for anything on the GPU?

MC6 is not the same as RC6 for the media tile?

Yes Bspec 66300 refers to these as core C states but refers to GT and
IA. So it's confusing.

Yup that's why I've left this as RC/RC6 in Patch v6.

Done in v6. Though this string is "on" also in the previous function
gen6_drpc. Also, if we are calling this C0 we could call the C6 state as
just C6 (which would mean RC6 for render and MC6 for media). But I thought
RC6 is better for both render and media.

Yes name is confusing but is the same as Bspec and also gen6_drpc. So the
prints "Media Power Well: Up" or "Media Power Well: Down" are correct (0 is
down, 1 is up). Similarly for Render below.
Thanks.

Sorry didn't understand what you mean by "slip", you mean the patch should

This function is called for both render and media gt's. But let's think
about this. We can call easily call them e.g. RC6 for render and MC6 for
media too if that is more accurate and descriptive. On the other hand, do
we really need to introduce a new term like MC6? Maybe we just stick to
RC/RC6 terminology for anything on the GPU?

Yes Bspec 66300 refers to these as core C states but refers to GT and
IA. So it's confusing.

Yup that's why I've left this as RC/RC6 in Patch v6.

Done in v6. Though this string is "on" also in the previous function
gen6_drpc. Also, if we are calling this C0 we could call the C6 state as
just C6 (which would mean RC6 for render and MC6 for media). But I thought
RC6 is better for both render and media.

Yes name is confusing but is the same as Bspec and also gen6_drpc. So the
prints "Media Power Well: Up" or "Media Power Well: Down" are correct (0 is
down, 1 is up). Similarly for Render below.
Thanks.

I saw people using this in some bug, but I thought this was for the package
since they were refering to the rc6 as well...
so you can see how confusing this bad naming is by itself... not a single
document or bspec page that put a good name we can use... so let's not
invent it here and move with the RC6.

oh, now that we agreed on staying with the RC I believe RC0 is better.

I saw people using this in some bug, but I thought this was for the package
since they were refering to the rc6 as well...
so you can see how confusing this bad naming is by itself... not a single
document or bspec page that put a good name we can use... so let's not
invent it here and move with the RC6.

oh, now that we agreed on staying with the RC I believe RC0 is better.

:( oh, indeed!
