drm/i915: Kconfig option to disable the legacy fbdev support Boots Just Fine (tm)! The only glitch seems to be that at least on Fedora the boot splash gets confused and doesn't display much at all. And since there's no ugly console flickering anymore in between, the flicker while switching between X servers (VT support is still enabled) is even more jarring. Also, I'm unsure whether we don't need to somehow kick out vgacon, now that nothing else gets in the way. But stuff seems to work, so I don't care. Also everything still works as well with VGA_CONSOLE=n Also the #ifdef mess needs a bit of a cleanup, follow-up patches will do just that. To keep the Kconfig tidy, extract all the i915 options into its own file. v2: - Rebase on top of the preliminary hw support option and the intel_drv.h cleanup. - Shut up warnings in i915_debugfs.c v3: Use the right CONFIG variable, spotted by Chon Ming.

drm/i915: Make AGP support optional We only depend on the intel-gtt module for GTT frobbign on older gens. The intel_agp module is optional, except for UMS and some old XvMC userland on gen3. So make AGP support optional. As before, we will fail the i915 init for UMS and gen3 KMS the same as before if intel_agp isn't around. intel-gtt.c is left with a somewhat ugly ifdef mess, but I'm going to save that for a later cleaning. At least my gen2 still works with the patch and CONFIG_AGP=n. v2: Make i915 depend on X86 and PCI, and intel-gtt depend on PCI Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

Choose this option if you have a system that has "Intel Graphics
Media Accelerator" or "HD Graphics" integrated graphics,
including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
Core i5, Core i7 as well as Atom CPUs with integrated graphics.
If M is selected, the module will be called i915. AGP support
is required for this driver to work. This driver is used by
the Intel driver in X.org 6.8 and XFree86 4.4 and above. It
replaces the older i830 module that supported a subset of the
hardware in older X.org releases.
Note that the older i810/i815 chipsets require the use of the
i810 driver instead, and the Atom z5xx series has an entirely
different implementation.

drm/i915: Deprecated UMS support It's been 5 years since kms support was merged and roughly 4 years since UMS support was ripped out from userspace drivers. Thus far it's not been a big burden to keep the ums paths alive, and we've made some good progress in better separating it from the kms code by sprinkling DRIVER_MODESET checks all over the place. But now that the drm demidlayering is within reach this changes. I want to make the driver loading code more robust using devres.c and other cool tricks. But that doesn't work with ums due to the shadow-attach trick. Which means we either a) need to split out a complete ums codebase like radeon has b) kill it for good. The 2nd option is obviously much less work than the first, so I think it's time to test the waters and see how many people out there still use ums. I've decided that silently failing to initialize the driver (and not e.g. failing to load the module) is the right thing. That way we should only get reports from users that actually care about some ums features (like accelerated gl or support for secondary outputs). Everyone else will just fall back to the vesa X driver. For developers there's a small info level dmesg output. The plan is to drop this Kconfig option after 3.16 (so gives us 2 full releases) and then start killing code for real 2-3 releases afterwards. That should be more than enough time for users to pipe up. Of course if anyone does we need to revisit this plan and maybe go with option a) above. Also enable the KMS support by default in Kconfig and polish the help texts a bit. v2: Add the missing hunk of actual code changes. Oops.
