[PATCH 00/15] drm/i915/bios: mipi sequence block v3, etc.

[Jani Nikula]

Hi all, this is follow-up to my earlier opregion/vbt series [1]. This
covers patches 1 and 7 of Deepak's series [2], but does quite a bunch of
rework to make everything as neat as it can be given the spec. There's
also some generic VBT documentation.

Unfortunately I haven't been able to test this on a machine that
actually has MIPI sequence block v3. However most of the series does not
touch that yet.

BR,
Jani.

+ * DOC: Video BIOS Table (VBT)
+ *
+ * The Video BIOS Table, or VBT, provides platform and board specific
+ * configuration information to the driver that is not discoverable or available
+ * through other means. The configuration is mostly related to display
+ * hardware. The VBT is available via the ACPI OpRegion or, on older systems, in
+ * the PCI ROM.
+ *
+ * The VBT consists of a VBT Header (defined as &struct vbt_header), BDB Header
+ * (&struct bdb_header), and a number of BIOS Data Blocks (BDB) that contain the
+ * actual configuration information. The VBT Header, and thus the VBT, begins
+ * with "$VBT" signature. The VBT Header contains the offset of the BDB
+ * Header. The data blocks are concatenated after the BDB Header. The data
+ * blocks have a 1-byte Block ID, 2-byte Block Size, and Block Size bytes of
+ * data. (Block 53, the MIPI Sequence Block is an exception.)
+ *
+ * The driver parses the VBT during load. The relevant information is stored in
+ * driver private data for ease of use, and the actual VBT is not read after
+ * that.

There's two blocks to parse, have one function per block. The existing
one cuts neatly into two.

[PATCH 04/15] drm/i915/bios: have get_blocksize() support MIPI sequence block v3+

[Jani Nikula]

Have get_blocksize() support the special case of MIPI sequence block v3+
which has a separate field for size. Provide and use abstractions for
getting the blocksize given a pointer to the block "envelope",
i.e. pointer to the block id, and given a pointer to the block payload
data.

[PATCH 11/15] drm/i915: Adding the parsing logic for the i2c element

[Jani Nikula]

From: vkorjani <vikas.korjani@intel.com>

New sequence element for i2c is been added in the
mipi sequence block of the VBT. This patch parses
and executes the i2c sequence.

v2: Add i2c_put_adapter call(Jani), rebase

v3: corrected the retry loop(Jani), rebase

v4 by Jani:
 - don't put the adapter if get fails
 - print an error message if all retries exhausted
 - use a for loop
 - fix warnings for unused variables

[PATCH 13/15] drm/i915/bios: add support for MIPI sequence block v3

[Jani Nikula]

The changes since the sequence block v2 are:

* The whole MIPI bios data block has a separate 32-bit size field since
  v3, stored after the version. This facilitates big sequences.

* The size of the panel specific sequence blocks has grown to 32
  bits. This facilitates big sequences.

* The elements within sequences now have an 8-bit size field following
  the operation byte. This facilitates skipping unknown new operation
  bytes, i.e. forward compatibility.

[PATCH 14/15] drm/i915/dsi: skip unknown elements for sequence block v3+

[Jani Nikula]

The sequence block has sizes of elements after the operation byte since
sequence block v3. Use it to skip elements we don't support yet.

Commit message should mention that you make the parsin more robust and
ensure we don't walk over the end of the allocated buffer.

Should dropping the +3 be in a separate patch?

Otherwise looks good, with the above 2 addressed

Really I'd rather not if you don't mind. The end result is the same, but
I'd have to think the function over again just to add a throwaway
intermediate step. Unless I just replace the return statement with
"return data + index - 3" which would feel a bit silly, don't you think?

Jani.

[PATCH v2] drm/i915/bios: abstract finding the panel sequence block

[Jani Nikula]

Make the whole thing easier to read. While at it, make the parsing more
robust, and ensure we don't read past buffer being parsed.

v2: improve commit message (Daniel)

Maybe DRM_ERROR in the previous patch too? Just for ocd consistency.

&& exec_elem[operation_byte] is redundant since you assing it to NULL
anyway in the else clause. While I bikeshed: Might look prettier with ?:

DRM_ERROR, like in the other cases we fail to parse the sequence fully?

Either way on both bikesheds: Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>

Silly me.

I might prefer an if-else if the ?: doesn't fit on one line.

I suppose we could add that in intel_bios.c to do it a limited number of
times at driver load, but here it would keep spewing out the errors
every modeset and possibly more. This is not necessarily a showstopper
with sequence v3, as we have the size to move on to the next one.

[PATCH v2] drm/i915/bios: add support for MIPI sequence block v3

[Jani Nikula]

The changes since the sequence block v2 are:

* The whole MIPI bios data block has a separate 32-bit size field since
  v3, stored after the version. This facilitates big sequences.

* The size of the panel specific sequence blocks has grown to 32
  bits. This facilitates big sequences.

* The elements within sequences now have an 8-bit size field following
  the operation byte. This facilitates skipping unknown new operation
  bytes, i.e. forward compatibility.

v2 (of the patch): use DRM_ERROR for unknown operation byte

[PATCH v2] drm/i915/dsi: skip unknown elements for sequence block v3+

[Jani Nikula]

The sequence block has sizes of elements after the operation byte since
sequence block v3. Use it to skip elements we don't support yet.

Somewhat off topic, but I wonder if this is correct. The "structure"
diagram shows it as 2 bytes for v1 and v2, but I'm not sure that section
isn't there just as an example. Later the describing the GPIO block it
seems to say it's 2 bytes for v1, and three bytes for v2.

This one isn't show in the structure diagrams at all, so I guess we get
to trust the other section. It says this was introduced in v2. Should be
add a paranoia check for that?

Should we also check that the payload length is below the specified max
of 240 bytes?

I've held on to some old spec versions (bdb version 177 has sequence v1,
bdb version 185 has sequence v2). Both v1 and v2 have 2 bytes payload
for the GPIO element.

The *meaning* of the first of those bytes has changed from v1->v2
though. Can't do much about that here, it's up to the generic vbt dsi
"driver"...

The spec with bdb version 185 has this.

I contemplated adding a check for v2, but then I thought it probably
doesn't really matter all that much. If we get an i2c elem with v1 and
reject it, we'll probably end up with a black screen. If we just assume
it's an i2c element but it isn't, it'll trip over something else later.

> Should we also check that the payload length is below the specified max

You'll love this. In v2 the max is actually the whole byte i.e. 255. In
v3 they added a length field for these operations for forward
compatibility (can now skip unknown new operations). And that's 8
bits. So the header + payload for the i2c data can't exceed 255, so
there's now an arbitrary 240 byte limit for i2c payload in v3.

BR,
Jani.

I don't really see where the 240 comes from. The spec lists 240 byte
payload size limit for i2c, spi, and send packet operations, but the
size of the header is different for those so I can't see how all
would end up with the same payload length limitation. So to me it seems
like the max payload limit should be 255-7 for i2c, 255-6 for spi, and
255-4 for send packet (since the "size of operation" byte doesn't seem
to include itself or the "operation byte"). So to me the 240 seems like
a totally arbitrary limit.

Can't comment on the v2+ part since the spec fails to mention it, but
otherwise looks sane.

It's a bit hard to review w/o an explicit assignments for each, but
assuming the MIPI_SEQ_DEASSERT_RESET value is correct these should be
correct too.

Not sure why we stopped at "tear on" though? The spec has "tear off",
"panel on" and "panel off" listed as well.

Just for lols. The sequence block v2 stops there. The rest are added at
v3. Words fail me.

I'm trying to find who is responsible for registering i2c busses with
these magic bus numbers. So far I can't see anything that would be doing
it.

Should we check total to make sure we don't access beyond what's

Could avoid a bit of typing/potential typos with some preprocessor tricks.

But anyways

We're in agreement that the spec seems just whimsical about this.

However this patch is for mipi vbt sequence block v2, which doesn't have
the limit. Can you r-b so we can move forward please?

*cough* I'm not sure either *cough*

Would you prefer adding a dummy mipi_exec_i2c that just eats and ignores
the data at this point? It would be a step forward. Now the driver just
gives up on encountering an unknown element.

Jani.

[PATCH v3] drm/i915/bios: add support for MIPI sequence block v3

[Jani Nikula]

The changes since the sequence block v2 are:

* The whole MIPI bios data block has a separate 32-bit size field since
  v3, stored after the version. This facilitates big sequences.

* The size of the panel specific sequence blocks has grown to 32
  bits. This facilitates big sequences.

* The elements within sequences now have an 8-bit size field following
  the operation byte. This facilitates skipping unknown new operation
  bytes, i.e. forward compatibility.

v2 (of the patch): use DRM_ERROR for unknown operation byte
v3 (of the patch): even more bounds checking (Ville)

[REPLACEMENT PATCH 11/15] drm/i915: skip the i2c element in the generic VBT DSI driver

[Jani Nikula]

Don't choke on unknown elements when we do know how to skip them.

[PATCH v5] drm/i915: Adding the parsing logic for the i2c element

[Jani Nikula]

New sequence element for i2c is been added in the
mipi sequence block of the VBT. This patch parses
and executes the i2c sequence.

v2: Add i2c_put_adapter call(Jani), rebase

v3: corrected the retry loop(Jani), rebase

v4 by Jani:
 - don't put the adapter if get fails
 - print an error message if all retries exhausted
 - use a for loop
 - fix warnings for unused variables

v5 by Jani:
 - rebase on the skip i2c element patch

I did just that, there's now a new 11/15 just skipping, and this one is
moved at the end. Also sent the rebased version of that.

Re: [PATCH v5] drm/i915: Adding the parsing logic for the i2c element

[Jani Nikula]

I screwed up something, the authorship for this one should have remained

From: vkorjani <vikas.korjani@intel.com>

Can be fixed while applying, will not resend now.

Sure. I'll take your word on the v2 vs. v3 thing since the spec is
absolutely useless here.

As far as the i2c bus numbering goes, I think we ought to add a check to
make sure the magic bus number is below __i2c_first_dynamic_bus_num.
That might catch the cases where some firmware related code forgot to
register the magic bus numbers.

Also the spec says 0xff would mean gmbus. So seems like we should handle
that in a special way. But I can't see where it would actually specify
the actual gmbus pins we should use, so I guessing no one actually even
tried to use this option since it simply can't work.

This was https://bugs.freedesktop.org/show_bug.cgi?id=93693 but has since
been fixed.

This sounds plausible if the panel actually has DPCD controlled
backlight; I was unable to confirm from the CI logs. The BIOS probably
enables the PWMs at boot, and then we don't disable.

What confuses me is that the backlight works on the machine *without*
your patches. IIUC your patch should only enable DPCD backlight control
if the DPCD says PWM control is not available.

Whether it makes sense or not, I predict the BIOSes of all machines to
blindly enable the PWMs. Including when the panel really doesn't support
PWM control. So we need to sanitize these registers.

See the comment in lpt_disable_backlight, this is already the case for
CPU PWM when only PCH PWM is used. I think the right approach would be
to sanitize the state at setup time instead of disable time.

The BDW in question is some development platform, I don't think you
could buy it. So it's a bit special, but we have it in CI because it has
some other features we like to test. Not sure how much conclusions one
can really draw from it.

BR,
Jani.

Re: ✗ warning: Fi.CI.BAT

[Adebisi, YetundeX]

Hi,

I got this message in reply to this patch (https://patchwork.freedesktop.org/patch/60736/). 

It looks like most of the warnings are related to  'PWM1 enabled' warnings that happen when the hardware is going into some power management state and BLM_PWM_ENABLE and/or BLM_PCH_PWM_ENABLE are enabled on the bdw-ultra platform.

What is the best way to fix this? If my patch is used then the function that disables BLM_PWM_ENABLE and/or BLM_PCH_PWM_ENABLE (lpt_disable_backlight) will not be called. 

Should I disable this DPCD backlight control featured  for BDW or specifically disable these bits in my intel_dp_aux_enable_backlight function?

Thank you.

Yetunde

Unrelated, apparently new so filed:

Known unrelated issue:
  https://bugs.freedesktop.org/show_bug.cgi?id=93768

Please do this type of analysis in the future every time CI result is

That I take it is this:

This is the age old
[drm:vlv_check_no_gt_access [i915]] *ERROR* GT register access while GT waking disabled
https://bugs.freedesktop.org/show_bug.cgi?id=93121

So these have nothing to do with these patches it seems.

This is a pre-existing bug already tracked in

This seems to be a very sporadic issue on bdw-ultra with pipe B/C and
the rpm wakelock check. Preexisting, but not yet tracked in bugzilla it
seems. I created a new one:

I got this email sent to me. It seems one of my patch causes this 
issue? Does anyone know how to find which patch causes this issue from 
the below message? Thanks.

Best Regards,
Libin
