Subject: Linux 2.3.18ac3

The big ones here are the new config files. They are now consistent about
EXPERIMENTAL. Driver authors please check if you think the tagging is
right. Its now consistent, but the old values were not so at times David
has guessed which of the several counterclaims you meant.

Also the MODULE_PARM change should clean up __setup stuff for many people.
Some drivers have MODULE_PARM inside ifdef MODULE at do not want it now,
some vice versa.

Subject: Re: IDE Driver in Linux Reports different geometry that Netware
during Volume and Partition Create, causing loss of user data under Linux

Andries,

I changed the drive setting to "AUTO" in the CMOS for this drive, and now
the drive reports 850/63/64. It is interesting to note that there was no
setting for this disk device that matched any of the configurations you gave
me. Long ago I wrote an IDE driver on Netware (Wolf Mountain), so I am
aware of the ability to translate drives into other logical geometries and
am very famliar with low level IDE stuff (unfortunately). The one thing
that sucks about IDE and ATA is that both use IO port reads and writes to
transfer data to and from the disk (which sucks up a lot of bus cycles).
It's better, however, to get this type of info to the right folks who
maintain the driver. There are several IDE drivers out there on other OS's
that for some reason did not implement the new commands for EIDE when they
came out. I try to focus on the stuff I am supposed to be working on and
not trying to fix everyone else's bugs, but report then to them instead. I
did not know if there were underlying hardware issues that I was unaware of
since it's been about two years since I did any IDE work. I thought someone
else may be more recently on top of it (like you).

Thanks for the help. I am relieved to know that the Linux IDE drivers are
not busted and don''t have any cross platform issues that will cuase
different OS's to report different geometry.

Thanks,

Jeff

Geee... Is that a problem? I've seeing 0k shrd in a 486DX2
since 2.3.16 here. I thought it was extremely strange, but for
some reason I didn't report.

And this happens with 2.3.1[678], which were the first
versions I tried on that 486.

I also see that 2.3.x is *MUCH* more memory hungry than 2.2.12
(for instance) regarding memory on a 8MB machine (this 486).

I can give much details if anybody wants me to.

[]s, Roger...

Subject: SCSI interrupts, system latency

ok, for the past few months i've been baffled.

this workstation is abhorently slow. mouse moves, keyboard typing, etc.
lagged, jerky, dropped actions, etc.

i put 2.3.18 on today to see if there was any better performance.

sequence of events:

- - boot
- - five minutes pass with no activity
- - i log in and cat /proc/interrupts

lo and behold:

there isn't any disk seeking happening. the heads are silent. there is an
onboard adaptec which gave the same symptoms. it was disabled and the above
card was installed.

if anyone has any ideas, feel free to inform me. further information avail
upon request.

XFree86 4.0 is supposed to do this as well... If only I owned a monitor
which was new enough to support it........

Subject: MTRR setting and framebuffer driver

vesafb tries to set a 2.5MB MTRR on my machine. This makes sense: I
have 2.5MB video memory

The MTRR driver rejects this as not a power of two.
That's fair, but not necessary in this case.

Because the 2.5MB region is a PCI region, it is power-of-two aligned,
and effectively carves 4MB in PCI mmio space.

vesafb doesn't know that: it only knows what the Vesa BIOS reports.

But we know that because we can see it in the mmio resource tree. The
2.5MB region is a subregion of a 4MB region.

Request
- -------

I would like either vesafb, or the MTRR driver to realise that this
2.5MB region is a sub-region of the 4MB region that won't be used by
anything else, so it is safe to allocate a 4MB write-combining MTRR.

Richard, is this possible now that we have the resource tree to examine?
Perhaps it is possible to generically permit rounding an MTRR range,
provided the extra address space is not used in the resource tree, and
if this condition changes in the tree, to remove the MTRR.

i'm a software engineer in Genius Company.
we have some products(e.g. mouse,net adapter...).
they need drivers in linux,but i'm a novice in developing linux device =
driver.So if you are interested in writting some driver (e.g. net =
