[RFC] New x86 Super BSP

[RFC] New x86 Super BSP

[Ross Burton]

Hi,

This is a RFC and not for merging just yet.  The goal is a BSP in meta-yocto-bsp
to replace atom-pc that supports "most" comtempory x86 hardware.  It starts off
as atom-pc but adds more X drivers, more firmware, and more framebuffer kernel
drivers.  Next up, more network drivers, more open X drivers and [handwaves]
stuff.  The precise set of hardware that this is expected to mostly work on
isn't settled on yet so feedback and boot testing is welcome.

[PATCH 1/6] genericx86: add new BSP

[Ross Burton]

This BSP aims to support "most" contemporary x86 hardware.  It's a direct copy
of atom-pc initially.

[PATCH 3/6] genericx86: add fbdev, modesettings and vesa Xorg drivers

[Ross Burton]

This should ensure that X can start on more hardware.  The range of hardware is
still small as the atom-pc kernel only has limited framebuffer devices currently
(e.g. no nVidia).

Which drivers do you have in mind here? AFAICT this patch set / BSP only
supports the i9x5 family of drivers out of the box, where this is not an
issue. In this day and age rootless X should be the norm, not the
exception, so I think it would be preferable to document the need to
disable rootless X with any such substandard drivers rather than have a
suboptimal lowest common denominator for the generic x86 machine.

In X is supports Intel gen hardware directly, and anything that it has
framebuffer or modesetting kernel drivers for (so anything with a
plain vesa framebuffer *should* work).

There's also a big difference between running X as root and the
session as root.  I've been meaning for a long time to implement that
split in the session scripts so that we're not by default running Sato
as root, just the X server.
