Hi,
I am developing a platform using a custom PPC board. CUrrently, I am
using the SIIG 3 port adapter, and have an IDE drive with an ADS FireWire
enclosure. Pretty standard stuff.
In the 2.4.4 HHL kernel I started out with, the version of the iee1394 subsystem
was only the following files:
aic5800.c highlevel.c ieee1394_syms.c pcilynx.c video1394.c
csr.c hosts.c ieee1394_transactions.c raw1394.c
guid.c ieee1394_core.c ohci1394.c
(No SBP2 driver).
So, I followed the instructions on the homepage, and downloaded (via CVS)
all of the source code. I then ran into the following changes I needed to
make :
pci_lynx.c -- comment out call to pci_set_dma_mask(dev, 0xffffffff))
***** (got a linker error, not defined)
raw1394.c --
#if 0
INIT_TQUEUE(&req->tq, (void(*)(void*))queue_complete_cb, NULL);
#else
INIT_TQ_LINK(req->tq);
req->tq.routine = (void(*)(void*))queue_complete_cb;
#endif
***** INIT_TQUEUE not defined. Replacement code is friom previous driver.
nodemgr.c --
#if 0
INIT_TQUEUE(&hi->task, nodemgr_node_probe, host);
#else
INIT_TQ_LINK(hi->task);
hi->host->timeout_tq.routine = (void (*)(void*))nodemgr_node_probe;
hi->host->timeout_tq.data = host;
#endif
***** INIT_TQUEUE not defined. Replacement code is friom previous driver.
hosts.c ---
#if 0
INIT_TQUEUE(&h->timeout_tq, (void (*)(void*))abort_timedouts, h);
#else
INIT_TQ_LINK(h->timeout_tq);
h->timeout_tq.routine = (void (*)(void*))abort_timedouts;
h->timeout_tq.data = h;
#endif
***** INIT_TQUEUE not defined. Replacement code is friom previous driver.
The first time it booted, it got the following error:

So, I looked at slab.c and iffed out the sanity check to see how much

Anyway, the previous code ran fine, but I couldn't mount a disk
so it wasn't very useful. I am wondering if this isn't an endian
issue as I see some notes that there are some issues with this.
Has anyone gotten the TOT 1394 drivers running on HHL and PowerPC?
Perhaps there is some other patch I need?
Many thanks in advance.
