Heads up for PSARC/2003/432 Coherent Console
The integration of "PSARC/2003/432 Coherent Console" won't affect
you in the near-term unless you manage to get ahold of an XVR-100
framebuffer and an updated pfb driver.
This project brings the SPARC platfrom more closely in line with x86
by utilizing the kernel terminal emulator (tem) on SPARC when a
suitable framebuffer driver is available, reverting to backward
compatible behavior using PROM terminal emulation otherwise.
SUMMMARY OF MAIN FEATURES:
- Reduces the dependence on OBP for console rendering post-boot
- Avoids stopping the other CPUs during console output
- Increases console text scrolling speed
- Provides ANSI color text (sun-color)
OVERRIDING:
If you have a compatable framebuffer driver on your system, but
wish to override configuration of the kernel tem module, the
old PROM terminal emulation can be forced by adding the following
line to /etc/system:
set cons_tem_disable=1
DRIVER EARLY-ACCESS:
Now only pfb officially supports coherent console.
XVR-100 gate will be built with coherent console enabled system,
so that the pfb packages can support coherent console.
Early access to the pfb packages is provided at:
/net/xinxin.prc/work/console/coherent/pkg-onfly/
SUNWpfb - pfb driver
SUNWpfbcf - pfb fbconfig module
SUNWpfbw - pfb DDX module
For any bugs or feature requests, please file a bug (or rfe) with
product: Solaris, category: kernel, subcat: console.
For any other questions, comments, etc, please send email to
audio-china at sun dot com
Thanks,
The Coherent Console team
