Annotation of wikisrc/users/jakllsch.mdwn, revision 1.3

1.2       wiki        1: # Jonathan Kollasch
                      2: 
                      3: ## Unfinished Projects
                      4: 
                      5: ### x86 UEFI kernel loader
                      6: Building this for x64 UEFI requires the `ms_abi` function attribute introduced in GCC 4.4 or so.
                      7: This project uses Intel UEFI headers and some existing FreeBSD work.
                      8: Needs more work and cleanup, also toolchain updates.
                      9: Work has been done using the OVMF BIOS images for Qemu.
                     10: 
                     11: ### bcm47xx for evbmips
                     12: Boots multiuser on NFS root, needs more work and cleanup.
                     13: This project is on hold until there's a miniature userland that fits in 4-8MiB flash storage devices, on a flash-oriented file system.
                     14: [[!template id=man name="bce" section="4"]] and [[!template id=man name="bwi" section="4"]] would need refactoring to be bus-independent.
                     15: 
                     16: ### Conexant PCI DTV driver
                     17: I have some code for 23880-3 and 887 host interfaces.
                     18: This type of hardware is hard to find freely available docs for.
                     19: Tuner/demod drivers from Linux could be ported, but would still be GPLed.
                     20: Probably better to keep these drivers in userland.
                     21: 
                     22: Should try to coordinate with what FreeBSD is doing: <http://wiki.freebsd.org/HDTV>.
                     23: 
                     24: ### Memory-mapped PCI config access on x86
1.3     ! jakllsch   25: Needs cleanup, and maybe some more validation of MCFG tables.
        !            26: 
        !            27: ### Toshiba ACPI LCD backlight driver
        !            28: Loosly based on [[!template id=man name="vald" section="4"]]. Currently attaches to `TOS1900`/`VALZ`, but doesn't interact with this device.
        !            29: This driver should really attach to `\_SB.PCI0.GFX0.LCD` or
        !            30: `\_SB.PCI0.PEGP.VGA.LCD`, which are the devices that get notified of
        !            31: brightness button pushes, and contain the `_BCL`, `_BCM`, and `_BQC`
        !            32: methods that access the brightness adjustment function.
        !            33: Such an attachment does not appear to be possible (or at the very least, easy)
        !            34: at present.
