All SoCs since DPU 5.0.0 (and seemingly up until and including 6.0.0,
but excluding 7.x.x) have the tear interrupt and control registers moved
out of the PINGPONG block and into the INTF block. Wire up the
necessary interrupts and IRQ masks on all supported hardware.

Please move .len setting to a separate patch, it is not direclty related
to tear interrupt addition.

Initially I added separate _reg and _bit settings because reg was common
to both interrupts. However now as tear interrups use different reg it
might be better to first move DPU_IRQ_IDX out of this macro () and then
to add your tear_rd_ptr_intr as a single intr_idx.

It is directly related in that the TE registers reside in the extra
space beyond 0x280, but I can surely make that explicit in a separate
patch.

I assumed as much; then we do get the duplication of _reg but I guess
it's not too bad if the lines are nicely wrapped like in _pp[]. I'll do
so in a separate patch.

Hi Marijn,
Thanks for the patch.
I saw that in your commit msg, you mentioned that 7.x doesn't have
tearcheck in the INTF block -- can you double check that this is correct?
I'm working on SM8350 (DPU v7) and I'm seeing that it does have
tearcheck in INTF block.

Just wondering, how were the lengths calculated for the INTF blocks? The
values in general seem a little off to me.
For example, I'm looking downstream and it seems to me that the length
for the INTF_0 on MSM8998 should be 0x280. Similarly for SC7280, I'm
seeing that length for INTF + tearcheck should be 0x2c4.
Thanks,
Jessica Zhang

I confirm, according to the vendor drivers INTF TE should be used for
all DPU >= 5.0, including 7.x and 8.x
However I think I know what Marijn meant here. For 5.x and 6.x these
IRQs are handled at the address MDSS + 0x6e800 / + 0x6e900 (which means
offset here should 0x6d800 and 0x6d900) for INTF_1 and INTF_2. Since DPU
7.x these IRQ registers were moved close to the main INTF block (0x36800
and 0x37800 = INTF + 0x800).

We have discussed INTF lengths in [1]. The current understanding of the
block lengths can be found at [2]. Please comment there if any of the
fixed lengths sounds incorrect to you.

Got it, then the commit text should remove "control" and just say tear
interrupt registers. It got a bit confusing.
We will add the 7xxx intf tear check support on top of this series.

Please correct my understanding here, it was agreed to fix intf blocks
to 0x2c4 here https://patchwork.freedesktop.org/patch/522227/ but I dont
see this was merged?
It was agreed to first land INTF_TE and then add the higher addresses
but I dont see such a change, am i missing something?

It wasn't correct and has already been removed for v2 [1] after rebasing
on top of SM8[345]50 support, where the registers reside at a different
(named 7xxxx downstream) offset.

That might have been the case.

The wording here points to both the interrupt (MDP_INTFx_TEAR_INTR)
registers and control (INTF_TEAR_xxx) registers separately. Feel free
to bikeshed the wording in preliminary v2 [1]; should I drop the mention
of the control registers being "moved" from PP to INTF entirely, leaving
just the wording about the interrupt registers moving from
MDP_SSPP_TOP0_INTR to a dedicated MDP_INTFx_TEAR_INTR region?
> We will add the 7xxx intf tear check support on top of this series.
No need, that is already taken care of in an impending v2 [1] (unless
additional changes are required beyond the moved register offset).

These (for MSM8998) have been taken from downstream specifically; my
series starts using INTF_STATUS at 0x26C which conveniently is the
register right after 0x268, matching the fact that INTF TE and these
registers weren't supported/available yet on MSM8998.

There are many different downstream sources and tags with seemingly
conflicting/confusing information. For v2 [2] I've picked the highest
register used by the driver which is INTF_TEAR_AUTOREFRESH_CONFIG at
0x2B4 (but there might always be more registers that don't need to be
poked at by the driver, but contain magic debug information and the
like... those would be useful to capture in the dump going forward).

Seems like it, at least if I interpret [3] correctly. My series adds a
new define that will hardcode _len to 0x2B8 for now, and Dmitry/Konrad
can later extend it to whatever is stated by the correct downstream
source.

This was discussed just yesterday. And it wouldn't make much sense to
make such a change now, knowing that my v2 for this series - which isn't
even on the lists yet - will already change the INTF_BLK macro resulting
in unneeded conflicts. As requested by Dmitry, let's get INTF TE
processed first before rebasing the block length change?

Yes, that makes more sense to me. Drop the mention on control registers.

Ok, we will wait till you post v2 and see if that works for us without

Not entirely correct.TEAR_AUTOREFRESH_STATUS is at 0x2c0 for sm8350 and
sm8450 as well so 0x2b4 is a bit short. DPU code uses autorefresh status
today.Esp after your changes it will use the autorefresh status from
intf te which is at offset 0x2c0

Like mentioned above it should be 0x2c0 for intf block.
If you face any conflicting information in downstream code, you can
always check with me on IRC.

Revisiting this, I don't see current DPU code nor downstream 5.4 / 5.10
SDE techpack on some of my checkouts use this register, only
INTF_TEAR_AUTOREFRESH_CONFIG at 0x2b4..0x2b7. Am I missing something
critical here?

Ack, it looks like others landed these changes for me now via the
catalog rework, so I have just rebased and kept the lengths in.

Wow, I lost context since its been months since your last response.
But, I refreshed some of it. You are right, we use the status bits
present in the INTF_TEAR_AUTOREFRESH_CONFIG and INTF_TEAR_
AUTOREFRESH_STATUS is unused.
I got confused between the status bit present in the two registers as
both relate to autorefresh.
But, the offset of of INTF_TEAR_ AUTOREFRESH_STATUS is still at 0x2c0 as
i wrote before so 0x2c4 is the accurate length of this block.
And yes, all the blk lengths should be accurate now in the hw catalog
after the rework and reviews of that rework.
