[PATCH] a better Silicon Image SATA mod15 write fix?

[PATCH] a better Silicon Image SATA mod15 write fix?

[Jeff Garzik]

[-- Attachment #1: Type: text/plain, Size: 655 bytes --]


Anyone with a Silicon Image controller interested in testing this patch 
on a non-production box?

It adds support for a new, Silicon Image-specific DMA table which should 
not only reduce CPU utilization a bit, but hopefully also magically 
solve the "mod15write bug" that affected Silicon Image chipsets _when in 
combination with_ certain SATA drives.

Feedback from people with and without the affected SATA drives 
("mod15write" bug) is welcome.

This patch should apply against the latest 2.6.4-bkN snapshot version of 
sata_sil.c, but for ease I have attached the full 2.6 version of the 
driver as well (compressed, it's just over 4K).

	Jeff

Can you test Try4 as well?

    Timing buffered disk reads:  170 MB in  3.01 seconds =  56.56 MB/sec 
(with 2.6.4-mm2)

    running boonie on the 2.6.4-mm2 version hangs the computer, with no 
possibilities of doing anything (can't even use the magic SysRq keys), 
while on the 2.6.4-bk4 version using the patched version of sata_sil.c 
it doesn't exactly hang : it is still possible to switch from one 
console to another, but it's impossible to log into any of them (after 
typing in the password, you never get the prompt).
    here is the command I used :
    bonnie++ -u jdidron -d /tmp -x 10 -s 2g -n 32:30000:5:500 -m
