| |
Hi, all. I've released v1.13 of my MTRR (set Memory Type Range Registers) patch. It may be found at: http://www.atnf.csiro.au/~rgooch/kernel-patches.html
For those who don't know what this is about: you can gain an easy 2.5x speedup blitting images to your PCI video card if you have a PPro/PII.
This patch is against kernel 2.1.97.
NOTE: people with certain types of GigaByte SMP boards which have different BogoMIPS values for their processors or get lockups on boot should find this patch useful.
Changes since v1.12:
- Safer synchronisation of MTRR changes across CPUs
Could people please give this a thorough testing. I plan on submitting this to Linus soon. I'm hoping that all people experiencing lockups with SMP machines (such as the GigaByte boards) will find the problems are fixed.
Regards,
Richard....
