Linux 2.4.18pre3-ac1-aia21 (IDE patches)

[Anton Altaparmakov]

Alan's -ac series is back! To celebrate this I added in the IDE patches and 
an NTFS update which dramatically reduces the number of vmalloc()s and have 
posted the resulting (tested) patch (to be applied on top of 
2.4.18pre3-ac1) at below URL.

IDE Patches bring amazing performance gain!!!

[Anton Altaparmakov]

As a heads up, Andre Hedrick's (Andre sorry for the misspelling 
previously!) IDE patch improved the performance of my 7200rpm ATA100 IBM 
IDE hd from 28Mb/s to 38Mb/s as measured by hdparm -t /dev/hda, which is 
quite an improvement by anyones standards! Also hitting the disk with a lot 
of io maintains low latency and my mp3s aren't dropping out and my X 
session maintains interactivity. (-:

Considering I have seen many good reports and ZERO bad reports about the 
IDE patches it is really astonishing that the patches are not being applied 
to the 2.4.x kernel series... (especially as they were in the -ac series 
previously already)

Best regards,

Anton

There is one outstanding bad report in private.  This report effects the
Promise PDC20262 Ultra66 host only.  I tested it w/ a 1.13 BIOS and it
worked.  I suggested the individual upgrade to the lastest version from
Promise.  One should note this is a 48-bit addressing exception, for old
hardware.

Are you planning any update soon ?
If not, could you post a new revision with Config.help parts in linuxcert ?
If not, I will just take from aia1...

Which, BTW, is the margin that the German c't computer magazine also
figured against those DTLA3070xx drives.

Let's take Andre's patch for 2.4.18-pre4 already, it's been solid here.
No reason do delay it.

Also, it's high time Linux gets tagged queueing for ATA, FreeBSD has
been there for ages, just installed 4.4-RELEASE on a current box and
whoooooo hw.ata.tags=1 in /boot/loader.conf.local rocks with hw.ata.wc=0
(write cache off). I'll see if I find the time to do bonnie benchmarks
soon.

That's ok. -ac2 isn't out yet AFAICS... (-;

Do you have the configure help entries in there, too?

btw. -ac1-aia1 is working very well on my desktop here. At least I wasn't 
able to break it with anything I threw at it. In fact it is working much 
better than before both interactivity wise and io wise. (-8

Andre's IDE patch is in the ac2 cut. I took it out just to make testing easier
in case other people found -ac1 wasnt as reliable as I did 8)

Will -ac2 be hitting the mirrors shortly then?  BTW, you
mentioned in your earlier email you excluded the low-latency
patches.   Mind if I ask which of the many you are using?
mini-ll?  full-ll?  The sched-O1-H6 patch?

I've tried all sorts of variants, including mini-ll, ll and pre-empt

Is that the NTFS code which produces eighty five quintillion warnings
with the recommended gcc versions? :-)

Huh? You are referring to ntfs tng perhaps? No, this is just a small update 
to the existing ntfs driver (admittedly taken from ntfs tng but this little 
part shouldn't produce any compiler problems AFAIK).

This update makes ntfs use kmalloc instead of vmalloc for <= PAGE_SIZE 
allocations and since the majority of the allocations are <= PAGE_SIZE this 
is both a performance improvement and a decrease of load on the 128MiB 
vmalloc vm area.

There were people who reported problems under load due to failing vmallocs 
and concurrent ldt allocation problems. This patch should address those 
problems.

Best regards,

Anton
