Ian-
When I added the second patch to the first and rebuilt the kernel I was
able to send a dd of my disk over the net to my laptop! Yeah! You
rock! I wish I understood this kernel magic you do!
Even if it is not the best way to do things I think you should commit
this to head as it is better than what is there now!

Greeting-
Thanks to gonzo- I am able to boot my BeagleBone image in qemu-arm, but
it never goes multiuser. It hangs just before the login prompt after
displaying the date.
I also find that there is no network interface even though I start with
the -net user flag. Does anyone have the magic needed to get qemu-arm
to provide a network interface. It would be very handy to be able to
play with things in a VM as well as on the beaglebone.
Thanks!
-Brett

The login prompt is displayed by the program 'getty'. The file /etc/ttys
contains information about where it does this, e.g. on serial ports
(ttyu*) or virtual terminals (ttyv*).
Your qemu probably has some virtual serial port you can connect to from
the host OS. Or you should enable getty on the console or virtual terminal.
NB: my amd64 machine has another default /etc/ttys than my arm machine.
Ronald.

Greeting-
Since I got a getty on the console of the BeagleBone I did not even
look at /etc/ttys, but now that I have looked at it I see the Bone
image has the getty set on /dev/ttyu0 and nothing on /dev/console. I
am pretty sure now that is what the problem was. Thanks for pointing
me to /etc/ttys. I did not think of looking at it.
Unfortunantly in my quest to get networking going I seem to have killed
disk access in qemu. Not having good qemu luck.

I have updated clang RPI code based on SVN r244906 + pmap-wb-caches-fix.
Now default transfer mode is DMA. If you want to use PIO(previous method),
you can change it by following command anytime:
# sysctl hw.bcm2835.sdhci.pio=1
or add to /boot/loader.rc:
set hw.bcm2835.sdhci.pio=1
major change:
o fix critical bug caused panic in arm/arm/vfp.c
o fix VFP compatibility for existing world/apps using SIGILL
o add TMPFS and UNIONFS kernel config
o use tmpfs as /tmp
o merge pmap-wb-caches-fix.diff and arm-autotune-fix.diff by gonzo
o assign all DMA(DMA0-12) IRQs in bcm2835-rpi-b.dts
o increase DI_MAX_INTR_NUM to 16 (necessary for DMA IRQs)
o call rman_set_virtual if SYS_RES_MEMORY
o add transfer and transfer_end method to dev/sdhci
o add simple DMA controller (does not support linked operation)
o test implement DMA transfer for SD card I/O
o add hw.bcm2835.sdhci.pio for PIO transfer (disabled by default)
Note:
512 byte chunk is used for each DMA transfer of SD because eMMC have only 1KB FIFO.
PIO mode is always used for a request smaller than 512 byte.
DMA transfer is not so fast although the efficiency of the bus differs.
At this time, first trigger is invoked by same INT of PIO.
sys/dev/sdhci/sdhci.c should be rewritten to adapt the DMA controller.
Known Problems:
To store correct values to DMA engine, it uses D-cache invalidate all. (unknown reason, first
chunk only)
Some code using VFP hang.
You can get the pre-build image from my archives:
http://www.peach.ne.jp/archives/rpi/
Using config is here:

New kernel only is here:

Excellent, thank you!
How do you build your images, please? I'm using Ti Kientzle's scripts, and they
don't produce the same runnable images that you have prodiced.
Thanks!

Wonderful! Best of all, the console has a cursor! It's sitting there
building sysutils/LPRng on an NFS-mounted /usr/ports tree (though it
doesn't appear it will finish before the morning). No crash so far!

The problem appears to be that clang is folding two 32-bit stores into a =

Hi,
Thank you for trying.
> After a crash, the fsck at boot fails and causes a panic:
Yes, I got same the error :)
It is a bug of DMA transfer, you can continue with "set hw.bcm2835.sdhci.pio=1".
If possible, try to enter loader prompt, then
loader> set hw.bcm2835.sdhci.pio=1
loader> boot -v
You can enter pressing space bar while the kernel loading. (only few sec.)
If you don't have serial console, please add "hw.bcm2835.sdhci.pio=1" to /boot/rc.conf by other
machine.
After recovery, download new kernel then replace old one.
# fetch http://www.peach.ne.jp/archives/rpi/kernel/kernel-20130110.gz
# gzcat kernel-20130110.gz > /boot/kernel/kernel
# reboot

I'm using gonzo's script with some little modifying.
http://people.freebsd.org/~gonzo/arm/rpi/build-pi-image.sh
My host is amd64/clang.(cc=clang) I didn't test with gcc.
The test kernel is self building by clang in Raspberry Pi.

Thank you, Daisuke-san. I'm going to merge DMA driver and DMA transfers
support for SDHCI. Merging other SDHCI fixes require more testing (and
spec reading)
but they're on my ToDo list too. DMA driver needs some clean-up though
before it can be committed to the tree. I'll post my notes on it when
it's ready.

I forgot invalidating SDHCI side. I've fixed this issues.
Please take from src-244906-20130110.patch.gz and new bcm2835_dma.[ch]. (dated 2013/Jan/10)
So, now it should take invalidate range correctly instead of D-cache invalidate all.
FYI, my patch fix:
wrong high voltage selection in dev/mmc/mmc.c
workaround missing error handling in dev/mmc/mmc.c
wrong freq divider in dev/sdhci/sdhci.c
workaround Raspberry Pi HS mode issue in dev/sdhci/sdhci.c
Thanks,

Somewhat after the fact, as Daisuke has also experienced the same
issue and already posted the solution. But to be complete:

Booting with PIO (hw.bcm2835.sdhci.pio=1) solved the issue:

It seems READ DMA is still broken.
How about this one?

The source fix is attached in this mail.

My test for above case, the kernel is crashed at
pmap_nuke_pv() at /usr/src/sys/arm/arm/pmap-v6.c
I don't know reason.
But it seems caused after calling read_dma_next from DMA intr.

You have made changes to files in contrib/llvm/. Are these needed?

Did you run clang under ARM kernel? (not cross)
I think no need patch to contrib/llvm if it use OABI only.
I don't know about EABI. (currently dropped EABI in my patch)
However, you can not use clang completely until other patch is applied.
1) no vmrs/vmsr op code (used by VFP) in contrib/binutils/gas/config/tc-arm.c
2) no enough text size in sys/arm/include/vmparam.h, config/RPI-B-test13 (32MB or more is
recommended)
3) cannot change max text size in sys/arm/include/vmparam.h, sys/conf/options.arm
I don't know why MAX size under VA is limited so small.
The physical memory is allocated when it requires, isn't it?
Thanks,

You must use 20130108 image or update boot partition because of:
http://lists.freebsd.org/pipermail/freebsd-arm/2013-January/004555.html
o assign all DMA(DMA0-12) IRQs in bcm2835-rpi-b.dts
o increase DI_MAX_INTR_NUM to 16 (necessary for DMA IRQs)
Thanks,

Hi,
I have doubt if cpu_switch() of arm has a bug.
In swtch.S:L.334, if newtd->td_pcb (this is in stack pointer for
kernel) has an address accessed first for the old(current) thread,
data_abort_fault may occur.
When data_abort_fault occurs, data_abort_handler() tries to solve this
address from kernel_map. In this time, curthread and curpcb are
already updated in swtch.S:L.223-231. As this result,
data_abort_handler() will occur data_abort_fault in trap.c:L.301, again.
When I check, in other CPUs, after updating the root pointer of MMU,
curthread and curpcb are updated.
Would you please check this?
Thanks,
Kohji Okuno
