[PATCH v3 1/2] drm/i915/display: Use a sub-struct for fbc operations in intel_display

[Vinod Govindapillai]

As FBC can utilze the system cache in xe3p_lpd onwards, we need
a way to track which fbc instance is utilizing this cache. So we
would need to extend the intel_display with such a functionality.
Introduce a new fbc substruct and move the current fbc instance
array into that. Then the following patch can utilize this to
introduce functionaity to configure and track the system cache
usage by the fbc instance.

In general, please don't refer to "patches" in commit messages. Just
consider reading this commit message a year from now, wondering what
"the following patch" might refer to.

No need to resend for this.

[PATCH v3 2/2] drm/i915/xe3p_lpd: Enable display use of system cache for FBC

[Vinod Govindapillai]

One of the FBC instances can utilize the reserved area of SoC
level cache for the fbc transactions to benefit reduced memory
system power especially in idle scenarios. Reserved area of the
system cache can be assigned to an fbc instance by configuring
the cacheability configuration register with offset of the
compressed frame buffer in stolen memoty of that fbc. There is
a limit to this reserved area which is programmable and for
xe3p_lpd the limit is defined as 2MB.

v2: - better to track fbc sys cache usage from intel_display level,
      sanitize the cacheability config register on probe (Matt)
    - limit this for integrated graphics solutions, confirmed that
      no default value set for cache range by hw (Gustavo)

v3: - changes related to the use of fbc substruct in intel_display
    - use intel_de_write() instead of intel_rmw() by hardcoding the
      default value fields

I think overall the implementation feels a bit overwhelming. I mean
there are so many functions, so many checks, to the point of being
excessive.

Some comments inline.

The only user of this has !IS_SYS_CACHE_FBC_INSTANCE_NONE(display)
i.e. "if not none".

Would be more useful to check if it's "set" or "valid", and avoid the
double negative. And use a shorter name. Maybe a static inline function.

But I'm not even sure the display->fbc.sys_cache_id needs to be
abstracted away. It's not a complicated thing, and, more importantly,
it's all within the same file. If outside access was needed, yes,
abstract, but here, not convinced.

Maybe:

	if (fbc_sys_cache_id_valid(display->fbc.sys_cache_id))

I also don't think *all* of these functions should be prefixed with
xe3p_lpd_ because that's a monster, and makes all of this difficult to
read.

> +#define IS_SYS_CACHE_FBC_INSTANCE_EQUALS(__display, id)	((__display)->fbc.sys_cache_id == (id))

I think this feels cumbersome. Why not just check

	if (display->fbc.sys_cache_id == id)

inline, and it's obvious?

Again, I'm not sure if this function is really needed. Just inline?

Ditto. Especially odd how this multiplies and the user the divides by 64
* 1024.

My point above is that this function only calls wrappers and really does
nothing itself. It's too many layers for a simple thing.

fbc_sys_cache_disable()?

Ditto.

fbc_sys_cache_enable()?

Most of this function is two separate paths based on the parameter. I
think it would benefit from actually being two separate functions. So
why not just merge this with xe3p_lpd_fbc_set_sys_cache_usage() and
xe3p_lpd_fbc_clear_sys_cache_usage()?

I don't think this should check for HAS_FBC_SYS_CACHE(). I think
internally the function being called should check if sys cache has been
set. And make sure it's only set on where it's available.

Ditto. I'm also not sure why some places call the version with params,
and some others the version without params.

xe3p_lpd_fbc_update_sys_cache_usage() is the function that should check
for HAS_FBC_SYS_CACHE() in one place.

Well, maybe it should be renamed fbc_sys_cache_enable().

Ditto about checking for valid sys cache inside, not
HAS_FBC_SYS_CACHE().

Ack for the above suggestions. About the function naming, yeah it is
indeed bit complex, but was following the functions names being
followed in this file. Should it be prefixed with nvl /intel or just
fbc?  instead? Any suggestion?

Two paths update this register - setting up the cache for a fbc and
clearing it. Also soon there is going to be a workaround implemented
which we need to disable the read cache enable bit which is set on by
default. So I was thinking of intercept here and apply the wa

if (intel_display_wa(display, xxxx))
		reg &= ~FBC_SYS_CACHE_READ_ENABLE;

Initially from HAS my understanding was that this was supposed to be
set by a pre-os fw and driver dont modify this field. And this can
change per platform. But from the recent logs fro, these fields are set
as 0 and has to be programmed by the driver. (I am clarifying this with
the HW team). Anyway, this need to be variated per platform. In some
other component such 2MB was hard coded like this. So thought of
adopting that. Any suggestion?

Actually there are three paths to update this register (two separate
path to clear this register)

1. As part of enable FBC - depends on the fbc instance (with fbc mutex
taken). If sys_cache is not reserved by any other instance.

2. As part of disable FBC - depends on the fbc instance to avoid
clearing if this fbc didnt reserve the cache space. (with fbc mutex
taken)

3. Clear this register as part of sanitize call (upon setup_hw_state()
calls upon probe and resume) and intel_fbc_cleanup() upon module
removal. Not depend on the fbc instance.

So something like this make sense?

fbc_program_sys_cache(u32 reg)
{
	intel_de_write(reg)
}

fbc_sys_cache_reset(display)
{
	if (!HAS_FBC_SYS_CACHE())
		return

	fbc_program_sys_cache(0)
	fbc.sys_cache_id = SYS_CACHE_FBC_INSTANCE_NONE
}

fbc_sys_cache_disable(fbc)
{
	if (!HAS_FBC_SYS_CACHE())
		return

	if (fbc.sys_cache_id != fbc->id)
		return;

	fbc_sys_cache_reset(display)
}

fbc_sys_cache_enable(fbc)
{
	if (!HAS_FBC_SYS_CACHE())
		return

	if (fbc.sys_cache_id != SYS_CACHE_FBC_INSTANCE_NONE)
		return;

	fbc_program_sys_cache(val)

	fbc.sys_cache_id = fbc-->id
}

intel_fbc_enable() will call fbc_sys_cache_enable(fbc)

__intel_fbc_disable() will call fbc_sys_cache_disable(fbc)

and 

intel_fbc_cleanup() and intel_fbc_sanitize() will call
fbc_sys_cache_reset(display) as a general cleanup for this register.

I would honestly just go with fbc_sys_cache_ for all of them. We don't
have to prefix everything in the world with a platform that started a
new feature.

It's different when you deviate from existing functionality for a
platform, and need different implementations for different platforms.

Okay. But if the function needs to do platform deviation, you'll need to
pass display to it.

Shouldn't fbc have been disabled by the time of module removal? I think
the per fbc disable should've been called already, no?

I think you could add a drm_WARN_ON(fbc.sys_cache_id !=
SYS_CACHE_FBC_INSTANCE_NONE) in the module removal path instead.

Btw that could also be renamed FBC_SYS_CACHE_ID_NONE or something.

I'm personally not a fan of "program" in pretty much any function
naming. What does it mean to program something? Isn't the whole driver
programming the hardare?

Just fbc_sys_cache_write()?

You don't need this check, because...

...this will catch the same conditions.

Overall sounds better, but I'll probably need to see the patches to
grasp it.

The fbc debugfs should also have the info on whether the instance is
using the sys cache.

Overall issue: The fbc mutexes are per fbc instance, but nothing
protects display->fbc.sys_cache_id.

The places where this sys_cache_id can be changed to a valid fbc
instance id + fbc cfb offset are protected by the fbc mutex as part of
intel_fbc_enable and intel_fbc_disable. That's is what I was mentioning
in my prev reply. And the places where this sys cache usage register
reset happens is outside the fbc context - where sanitize and remove
module gets called. I don't see a need to update the fbc.sys_cache_id
from anywhere else.

That's not the point. Each FBC instance has its own mutex. Two FBC
instance mutexes could be held at the same time. I don't think this is
the case during enable/disable, though. But the point remains, the
instance mutex can't protect something that's not part of the instance.

Jani.
