| |
Hi Guys,
A long time ago I remember there was a guy working on a VESA FBconsole driver for Linux. Then driver he was working on was structured as a user land daemon that the kernel console driver would call back into once the system was up, allowing the userland VESA driver to use the vm86() service to change modes, program the palette and other useful things that can't be done by the basic driver that uses a mode set previously by LILO or GRUB.
My first question is, did this project ever get completed and included in the Linux kernel at all? Does anyone have any reference to this project that you can point me at?
My second question is, is it possible to execute vm86() services from *within* the kernel as opposed to from user land? I got the impression at the time that the userland daemon was used because vm86() could only be called from userland code and could not be called from within the kernel to execute real mode VESA BIOS services. Is that correct? If not, can vm86() services now be called from other kernel modules inside the kernel?
Feel free to email me directly with information if this is an FAQ to keep traffic off the list.
Thanks!
