Success fully tested on the b2k with k-2.6.0-pa4 32bit (still have to see for 64bit), that you could can guess as it is a model near c3k. What I test also with success :)) is the ide-cdrom wich seems to works fine (find about 5245 file on a iso-cd, tar tzslpf a 41Mb tgz file, vi some other files, ...) Here are the additional paramters I used: # # ATA/ATAPI/MFM/RLL support # CONFIG_IDE=y CONFIG_BLK_DEV_IDE=y # # Please see Documentation/ide.txt for help/info on IDE drives # # CONFIG_BLK_DEV_IDEDISK is not set CONFIG_BLK_DEV_IDECD=y # # IDE chipset support/bugfixes # CONFIG_BLK_DEV_IDEPCI=y CONFIG_BLK_DEV_IDEDMA_PCI=y CONFIG_BLK_DEV_ADMA=y CONFIG_BLK_DEV_IDEDMA=y Note that I have to add generic dma support because without I got following errors: CC drivers/ide/setup-pci.o drivers/ide/setup-pci.c: In function `ide_hwif_setup_dma': drivers/ide/setup-pci.c:511: warning: implicit declaration of function `ide_setup_dma' CC drivers/ide/ide-proc.o [snip] LD .tmp_vmlinux1 drivers/built-in.o(.text.ide_hwif_setup_dma+0x150): In function `ide_hwif_setup_dma': : undefined reference to `ide_setup_dma' make: *** [.tmp_vmlinux1] Error 1. hth, Joel >-- Original Message -- >Date: Sat, 20 Dec 2003 22:10:41 -0700 >From: Grant Grundler >To: parisc-linux@lists.parisc-linux.org >Subject: [parisc-linux] DIFF 2.6.0-pa3 suckyio USB support > > >Hi all, I finally figured out why suckyio USB was broken...lots of little things. I still can't start X11 but it's likely some other issue (.config file options likely - I'll post a seperate mail on that) Diff is at: ftp://ftp.parisc-linux.org/ >atches/diff-2.6.0-suckyio-03 I don't have time to testing this on all variants (a500 and c3k 64-bit). Please test, comment, and commit if it's looking good. I'll be around a bit but not really available to commit a final version until after chris >mas. Comments on PCI Config space, diffstat, and comments on the diff follow. FYA, the final problem was writes to PCI Configuration space. PCI is by nature a 32-bit bus and byte writes to config space seems to be broken. I'd like to blame suck >io for this but not sure I can. It might be broken for all systems with LBA. Or maybe my proto-C3K (v2.1 Elroys) is just broken. And I just sent my only other production C3000 to someone who is having a very happy christmas...

Restructured the hacks in iosapic_fixup_irq(), superio_fixup_irq() and superio_init() >to make the initialization sequence a bit more obvious. o simplify the suckyio serial_init() to use static initializers. Registering each port is really only three lines of code now. o fix iosapic bug where two EIR bits where getting allocated >in the case where two "devices" used the same iosapic IRQ line. Only one was actually used. Simple check midway down in iosapic_fixup_irq() takes care of that. The two functions of built-in SCSI 53c896 on C3000 exposed this bug. Both u >e INT A. Normally a multifuction device like 53c896 will use INT A and INT B. o remove "vi_" prefix from iosapic vector fields. Code is a bit more readable now. (sorry - it itched really badly :^) o moved pdc_io_reset_devices() call to s >a code. It's only needed for SBA systems which are NOT PAT PDC. Does NOT interfere with serial or pdc console. o added pdc_pci_config() accessor primitives but have not tested them. I thought I would need them but don't (yet). Left them in >lace in case someone cares to convert all the cruft in lba_pci.c to use PDC calls instead....PAT PDC has a different PDC interface but I can deal with that if someone takes care of "legacy PDC" systems. o added gmmio_base field and adver >ise MMIO resources above 4GB on 64-bit systems. Not well tested and may want to back this out if it even smells like a problem. o updated comments tulip/media.c and reduce timeout in tulip_select_media() to 1ms. o updated Kconfig help fo > unsupported CONFIG_PCI_EPIC (V-class only) o added copyright notice to files I've touched. enjoy! grant _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linu >.org/mailman/listinfo/parisc-linux ------------------------------------------------------------------------- Tiscali ADSL: 12 mois à 29,50 €/mois!
