 1.14  19-Dec-2021  riastradh Narrow scope of exclusions in drm_fb_helper.c; reduce diffs.
 1.13  19-Dec-2021  riastradh Restore drm_fb_helper_debug_{enter,leave}_fb

the non-fbinfo versions of the same function now that I see why
they exist, and that they are not a mangled diff


Author: Maya Rashish <maya@NetBSD.org>
 1.12  19-Dec-2021  riastradh Ifdef out linux framebuffer stuff in drm_fb_helper.
 1.11  19-Dec-2021  riastradh Ifdef out drm_fb_helper_ioctl too.
 1.10  19-Dec-2021  riastradh Forward decl to minimize patch.
 1.9  18-Dec-2021  riastradh Merge linux-drm-v5-6-rc3
 1.8  27-Aug-2018  riastradh Remove temporary drm_fb_helper_set_config stub from old code.
 1.7  27-Aug-2018  riastradh merge linux-drm-v4-4-143
 1.6  24-Jul-2014  riastradh branches: 1.6.4; 1.6.28; 1.6.30;
Expose drm fb helpers for ddb enter/exit.
 1.5  24-Jul-2014  riastradh Rework Intel framebuffer attachment.

Turns out genfb_softc must be at the start of its own device_private,
so we can't have it in the middle of a structure, and certainly can't
have potentially multiple genfbs per graphics device. Failing to do
this is why entering ddb didn't work with an i915drmkms console.

Instead of putting a genfb_softc into each drm_fb_helper, put a
device_t into each drm_fb_helper and create a new intelfb(4) device
for each Intel framebuffer. This will be more flexible, too, in case
we want accelerated framebuffers later on. (XXX Need to adapt the
radeon code, which I'm disabling until that happens to avoid breaking
the build.)

While here, defer disabling VGA, vga_cndetach, and genfb_attach until
we're actually ready to do them all together along with the mode
switch. This should reduce the amount of time during which the
screen is blanked, in case it hangs.
 1.4  16-Jul-2014  riastradh Make it build and boot on my test machines.

Screen blanks on boot on the Ivy Bridge system with

DRM error in cpt_serr_int_handler: PCH transcoder A FIFO underrun

But after that everything is OK. Appears to be an upstream problem.
To investigate...

I think there's a cache flushing issue somewhere -- there are little
display artefacts on my T60.
 1.3  16-Jul-2014  riastradh fix merge conflicts
 1.2  18-Mar-2014  riastradh branches: 1.2.2; 1.2.4;
Merge riastradh-drm2 to HEAD.
 1.1  23-Jul-2013  riastradh branches: 1.1.1;
