Revision 1.1.1.1 (vendor branch), Tue Mar 4 16:16:09 2008 UTC (16 years, 3 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)

* GNU C version 2.96 adds explicit branch prediction so that
* the CPU back-end can hint the processor and also so that
* code blocks can be reordered such that the predicted path
* sees a more linear flow, thus improving cache behavior, etc.
*
* The following two macros provide us with a way to utilize this
* compiler feature. Use __predict_true() if you expect the expression
* to evaluate to true, and __predict_false() if you expect the
* expression to evaluate to false.
*
* A few notes about usage:
*
* * Generally, __predict_false() error condition checks (unless
* you have some _strong_ reason to do otherwise, in which case
* document it), and/or __predict_true() `no-error' condition
* checks, assuming you want to optimize for the no-error case.
*
* * Other than that, if you don't know the likelihood of a test
* succeeding from empirical or other `hard' evidence, don't
* make predictions.
*
* * These are meant to be used in places that are run `a lot'.
* It is wasteful to make predictions in code that is run
* seldomly (e.g. at subsystem initialization time) as the
* basic block reordering that this affects can often generate
* larger code.
