Revision 1.1.1.1 (vendor branch), Tue Mar 4 16:14:50 2008 UTC (16 years, 2 months ago) by nbrk
Branch: OPENBSD_4_2_BASE, MAIN
CVS Tags: jornada-partial-support-wip, HEAD
Changes since 1.1: +0 -0 lines

Import of OpenBSD 4.2 release kernel tree with initial code to support 
Jornada 720/728, StrongARM 1110-based handheld PC.
At this point kernel roots on NFS and boots into vfs_mountroot() and traps.
What is supported:
- glass console, Jornada framebuffer (jfb) works in 16bpp direct color mode
(needs some palette tweaks for non black/white/blue colors, i think)
- saic, SA11x0 interrupt controller (needs cleanup)
- sacom, SA11x0 UART (supported only as boot console for now)
- SA11x0 GPIO controller fully supported (but can't handle multiple interrupt
handlers on one gpio pin)
- sassp, SSP port on SA11x0 that attaches spibus
- Jornada microcontroller (jmcu) to control kbd, battery, etc throught
the SPI bus (wskbd attaches on jmcu, but not tested)
- tod functions seem work
- initial code for SA-1111 (chip companion) : this is TODO

Next important steps, i think:
- gpio and intc on sa1111
- pcmcia support for sa11x0 (and sa1111 help logic)
- REAL root on nfs when we have PCMCIA support (we may use any of supported pccard NICs)
- root on wd0! (using already supported PCMCIA-ATA)

1. Investigate making ISOFS another UFS shared filesystem (ala FFS/MFS).
   Since it was modelled after the inode code, we might be able to merge
   them back.  It looks like a separate (but very similar) lookup routine
   will be needed due to the associated file stuff.

2. It would be nice to be able to use the vfs_cluster code.
   Unfortunately, if the logical block size is smaller than the page size,
   it won't work.  Also, if throughput is relatively constant for any
   block size (as it is for the HP drive--150kbs) then clustering may not
   buy much (or may even hurt when vfs_cluster comes up with a large sync
   cluster).

3. Seems like there should be a "notrans" or some such mount option to show
   filenames as they really are without lower-casing.  Does this make sense?
