While attemting to install alsa1.0.18a on a system based on Linux2.6.24,
I am stuck with:
alsa-kernel/core/hrtimer.c:29: error: implicit declaration of function
‘hrtimer_forward_now’
This function was introduced with kernel 2.6.25 - which also happens to
be the first kernel where RT-patches breaks for midi.
Anybody has got an idea for a workaround?

2.6.25.8-rt7 compiling as we speak. Lets see how that works out.

You'll need to regenerate configure script. gitcompile would do that
job.
I recommend you to use the snapshot tarball from
ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-sna…
This is created automatically at each update of my git trees below

Thanks!
This compiles (almost) cleanly, only with some warning(s) of the
following kind a little here and there:
warning: passing argument 1 of ‘get_unaligned_le16’ discards qualifiers
from pointer target type
include/asm/io_32.h:217: warning: passing argument 1 of ‘__memcpy’
discards qualifiers from pointer target type
...
Anymays: "ALSA modules were successfully compiled."
:-D

What I did in alsa-kernel/core/hrtimer.c to get it to compile with
2.6.24.7-rt17
+/* Forward a hrtimer so it expires after the hrtimer's current now */
+static inline unsigned long hrtimer_forward_now(struct hrtimer *timer,
+ ktime_t interval)
+{
+ return hrtimer_forward(timer, timer->base->get_time(), interval);
+}
+
... which is verbatim from kernel 2.6.25
Problem solved.

Sorry Jens, I can't help.
The people with real knowledge tell stupid people like me, that the
kernel 2.6.25 is better than the kernel 2.6.24.
At the end it looks like we need kernel 2.6.22 for 64bit, an experience
the 64 Studio developers made.

Was ich an der ganzen Sache nicht verstehe (und ich habe nun diesen
thread hier, deinen thread im Multimedia Forum, deinen post auf der
linux-audio-developers Liste und nun den im opensuse forum gelesen)...
Wenn es doch um die Unterstützung neuer Hardware geht, warum baust du
dir dann auf einer release-candidate Version von OpenSUSE 11.1 einen
kernel selber, der auf einer noch älteren Version von Linux basiert als
der in der aktuell stabilen 11.0?
Du baust da den 2.6.24er, 11.0 kommt mit 2.6.25-rt, jengelh bietet auch
.25er an. Das ergibt, wenn es um die Unterstützung neuer Hardware geht,
nicht wirklich viel Sinn, denn die kommt meist mit neueren Linux Versionen.
