linux-next: manual merge of the drm tree with the drm-misc-fixes tree

linux-next: manual merge of the drm tree with the drm-misc-fixes tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 1257 bytes --]

Hi all,

Today's linux-next merge of the drm tree got a conflict in:

  drivers/gpu/drm/meson/meson_crtc.c

between commit:

  47ebfb6ed13e ("drm/meson: Fixes for drm_crtc_vblank_on/off support")

from the drm-misc-fixes tree and commit:

  f9a2348196d1 ("drm/meson: Support Overlay plane for video rendering")

from the drm tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

linux-next: manual merge of the drm tree with the drm-misc-fixes tree

Hi all,

Today's linux-next merge of the drm tree got a conflict in:

  drivers/accel/ivpu/ivpu_hw_37xx.c

between commit:

  cc19fedab8bd ("accel/ivpu/37xx: Print warning when VPUIP is not idle during power down")

from the drm tree.

I fixed it up (see below) and can carry the fix as necessary. This

I've just run into the same conflict, and I think you lost the split
into two if-statements in the last hunk of commit 3f7c0634926d
("accel/ivpu/37xx: Fix hangs related to MMIO reset")?

linux-next: manual merge of the drm tree with the drm-misc-fixes tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 1261 bytes --]

Hi all,

Today's linux-next merge of the drm tree got a conflict in:

  drivers/accel/ivpu/ivpu_fw.c

between commit:

  645d694559ca ("accel/ivpu: Use cached buffers for FW loading")

from the drm-misc-fixes tree and commit:

  53d98420f5f9 ("accel/ivpu: Move ivpu_fw_load() to ivpu_fw_init()")

from the drm tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

This is a mess :-(  I have just reverted the above revert before mergin

Sorry for the noise, the patch "5e3f1e7729ec ("drm/amdgpu: fix start 
calculation in amdgpu_vram_mgr_new")" and another one is going to be 
reverted from the drm tree as well.

It's just that -fixes patches where faster than -next patches.

Christian.

Here we are a week later, -rc7 has been released and as far as I can
tell (though I may have missed it), this is still a problem :-(

I am still reverting 925b6e59138c (which is now in Linus' tree).

Thanks for the hint! After reverting that commit, drm-next (sort of[1])
merges cleanly into upstream again.

[1] There's still a small conflict due to the removal of
    force_dpms_off, cfr. the difference between commits
    3283c83eb6fcfbda and cc79950bf0904f58 ("drm/amd/display:
    Ensure valid event timestamp for cursor-only commits") in
    v5.19-rc7 resp. drm-next.

My assumption is I fix this on sending my -next tree to Linus with a
resolution I create at that time?

Is there another option, we have this fixed in out drm-tip tree already.

linux-next: manual merge of the drm tree with the drm-misc-fixes tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 796 bytes --]

Hi all,

Today's linux-next merge of the drm tree got a conflict in:

  drivers/gpu/drm/bridge/Kconfig

between commit:

  3c3384050d68 ("drm: Don't make DRM_PANEL_BRIDGE dependent on DRM_KMS_HELPERS")

from the drm-misc-fixes tree and commit:

  803abfd8dda5 ("drm: bridge: fix unmet dependency on DRM_KMS_HELPER for DRM_PANEL_BRIDGE")

from the drm tree.

I fixed it up (I just used the latter) and can carry the fix as
necessary. This is now fixed as far as linux-next is concerned, but any
non trivial conflicts should be mentioned to your upstream maintainer
when your tree is submitted for merging.  You may also want to consider
cooperating with the maintainer of the conflicting tree to minimise any
particularly complex conflicts.

But that failed during configuration, so I went back and used the
former change.

linux-next: manual merge of the drm tree with the drm-misc-fixes tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 801 bytes --]

Hi all,

Today's linux-next merge of the drm tree got a conflict in:

  drivers/gpu/drm/nouveau/nouveau_fence.c

between commit:

  67f74302f45d ("drm/nouveau: wait for the exclusive fence after the shared ones v2")

from the drm-misc-fixes tree and commit:

  40298cb45071 ("drm/nouveau: use the new iterator in nouveau_fence_sync")

from the drm tree.

I fixed it up (I just used the latter version) and can carry the fix as
necessary. This is now fixed as far as linux-next is concerned, but any
non trivial conflicts should be mentioned to your upstream maintainer
when your tree is submitted for merging.  You may also want to consider
cooperating with the maintainer of the conflicting tree to minimise any
particularly complex conflicts.

That will cause a performance regression in linux-next for nouveau users.

The real fix is already queued up for merging into drm-next. So no 
immediately action item here.

Just keep it in the back of your mind in case any nouveau users starts 
to complain about the performance in linux-next.

Thanks,
Christian.

linux-next: manual merge of the drm tree with the drm-misc-fixes tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 6144 bytes --]

Hi all,

Today's linux-next merge of the drm tree got a conflict in:

  drivers/gpu/drm/vc4/vc4_kms.c

between commits:

  f927767978d2 ("drm/vc4: kms: Fix return code check")
  d354699e2292 ("drm/vc4: kms: Don't duplicate pending commit")

from the drm-misc-fixes tree and commit:

  16e101051f32 ("drm/vc4: Increase the core clock based on HVS load")

from the drm tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Unfortunately the merge resolution isn't entirely correct :/

There's multiple conflicts between those two branches on that file, but
things went wrong between 16e101051f32 and 0c980a006d3f

The first one changes the logic a bit for the clk_set_min_rate argument,
and the second moves the clk_set_min_rate around.

However, the merge resolution reintroduced the initial clk_set_min_rate
call line (line 373), without changing the logic of the proper call site
(line 396).

This is the patch to fix the resolution:

I'm wondering though, do you have access to the drm-rerere tree? I've
fixed up the merge yesterday to deal with this conflict and the conflict
resolution should be stored there already.

linux-next: manual merge of the drm tree with the drm-misc-fixes tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 2198 bytes --]

Hi all,

Today's linux-next merge of the drm tree got a conflict in:

  drivers/gpu/drm/drm_panel_orientation_quirks.c

between commit:

  def0c3697287 ("drm: panel-orientation-quirks: Add quirk for Aya Neo 2021")

from the drm-misc-fixes tree and commits:

  072e70d52372 ("drm: panel-orientation-quirks: Add quirk for the Chuwi Hi10 Pro")
  63a4881572d7 ("drm: panel-orientation-quirks: Add quirk for the Chuwi HiBook")

from the drm tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

linux-next: manual merge of the drm tree with the drm-misc-fixes tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 821 bytes --]

Hi all,

Today's linux-next merge of the drm tree got a conflict in:

  drivers/gpu/drm/omapdrm/dss/dsi.c

between commit:

  690911544275 ("drm/omap: dsi: fix unsigned expression compared with zero")

from the drm-misc-fixes tree and commit:

  bbd13d6a7b2e ("drm/omap: dsi: fix unreachable code in dsi_vc_send_short()")

from the drm tree.

I fixed it up (these do basically the same thing, so I used the former
version) and can carry the fix as necessary. This is now fixed as far as
linux-next is concerned, but any non trivial conflicts should be mentioned
to your upstream maintainer when your tree is submitted for merging.
You may also want to consider cooperating with the maintainer of the
conflicting tree to minimise any particularly complex conflicts.

Yes, I messed that up. I accidentally merged a fix to drm-misc-fixes, 
but almost similar fix was already in drm-misc-next. Sorry about that.

Fix looks correct to me. Sorry for not testing my patch with
linux-next, I'll make sure it at least compiles next time.

This is merge conflict, not compile fail, because linux-next and drm-misc-fixes
are based on different code base, so drm-misc-fixes do not contain latest drm
commits.

This conflict solve change is also OK for me.

Thanks,

linux-next: manual merge of the drm tree with the drm-misc-fixes tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 1281 bytes --]

Hi all,

Today's linux-next merge of the drm tree got a conflict in:

  drivers/gpu/drm/arm/display/komeda/komeda_dev.c

between commit:

  51a44a28eefd ("drm/komeda: Add missing of_node_get() call")

from the drm-misc-fixes tree and commit:

  8965ad8433ea ("drm/komeda: Enable dual-link support")

from the drm tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Hi all,

Today's linux-next merge of the drm tree got a conflict in:

  drivers/gpu/drm/sun4i/sun4i_tcon.c

between commit:

from the drm-misc-fixes tree and commit:

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial

linux-next: manual merge of the drm tree with the drm-misc-fixes tree

[Stephen Rothwell]

Hi Dave,

Today's linux-next merge of the drm tree got a conflict in:

  include/drm/drm_atomic.h

between commit:

  7e9081c5aac7 ("drm/fence: fix memory overwrite when setting out_fence fd")

from the drm-misc-fixes tree and commit:

  bdc571464c49 ("drm/atomic: Clean up wait_for_vblanks, v2.")

from the drm tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
