Subject: [movitz-devel] Beginnings of a VMware graphics driver
Message-ID: <87sl7nndq7.fsf@muscle.bealbywm.plus.com>

People,

As discussed in the freak wave of discussion yesterday, here is a
preliminary VMware graphics driver.

It cannot be tested until the fifo commands are implemented, thus, bugs
may be present.  I am having trouble making these functions.  A (very)
brief description would be the fifo is a region of memory through which
pointers cycle through.

It is attached to this email as vmware.lisp.

One of the clearest reference codebases is the Syllable VMware graphics
driver.  You can find this at
http://syllable.cvs.sourceforge.net/syllable/syllable/system/sys/appserver/appserver/drivers/video/vmware/

Comments / suggestions / improvements very welcome.

Thanks,
Martin

Hi Martin, I checked your code into CVS at losp/tmp/vmware-vga.lisp.

One immediate comment is to always name your defvars
*like-this*. That's an age-old convention with good reasons behind it.

I'll probably tweak the code a bit in CVS.

Message-ID: <87ir8hz8au.fsf@muscle.bealbywm.plus.com>

People,

We are no longer limited to 300x240x256!

Please find attached a working bochs VBE extension graphics driver.
This driver has been tested in both bochs and qemu (requires -std-vga
option in qemu).  It will not work on real hardware.

Remember, you will need to add the line "(require :x86-pc/bochs-vbe)" to
all.lisp in x86-pc directory to include it in your image.

The next step is to abstract the framebuffer drawing commands from
vga.lisp and place them into a separate file for use with any graphics
driver.

Happy hacking,
Martin

Great work Martin, I checked it in to CVS now.
