[Jeff Chua]

uml-patch-2.4.22-7 on linux 2.4.24-pre1

Can't compile without CONFIG_MODE_TT. 2.4.22-5 has no problem.


Command to compile (make linux ARCH=um)


Thanks,

[uml-devel] [PATCH] - fix for 2.4.22-7um RTC on CPUs faster than 2.1 GHz

[Christopher S. Aker]

Enabling the RTC in 2.4.22-7um produced a hang very soon after INIT at boot time.

I discovered host_hz as an int overflows past 2.1 Ghz (2147483647 hz).  An
unsigned int/long would only work for up to ~ 4.3 Ghz (4294967295 hz) or so, which
isn't that far off, imo...  So -- Below is a patch that changes the type of
host_hz to unsigned long long.  Also, I believe some casting was taking place with
the return value of get_host_hz, so mhz is also redefined as an unsigned long
long.

Sigh, some people's machines are too fast...

Applied, thanks.

Does this mean this fix is included in the 2.4.22-7 patch on your
website, a new -7 will be released shortly with this fix, or -8 will be
released shortly with this (and other) fixes?

It'll be in -8.  I don't reuse patch numbers.

Ah, I've been wondering why I couldn't get 2.4.22-7um to work - this
fixes it for me!

BTW the patch appeared to be whitespace mangled - I had to apply it
with patch --ignore-whitespace

Thanks

Nick

Would you either post the fix or release -8? Or maybe it's on CVS(but you post 
a release for each CVS commit, right?)

In general:
Maybe before than on the site you should announce the release here providing 
the file as a link, get the silly compile errors and release on the site the 
patched version. Since -6 to -7 hostaudio needed that silly fix for 
modules... it's so unpleasant.

Or just build or use a compilation test-suite...
