The following issue has been RESOLVED. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1907> ====================================================================== Reported By: xaoslaad Assigned To: tiwai ====================================================================== Project: ALSA - driver Issue ID: 1907 Category: PCI - maestro3 Reproducibility: always Severity: minor Priority: normal Status: resolved Distribution: Fedora Core 5 Test 3 Kernel Version: kernel-xen0-2.6.15-1.2038_FC5 Resolution: not an issue Fixed in Version: ====================================================================== Date Submitted: 03-11-2006 02:29 CET Last Modified: 07-11-2006 12:35 CEST ====================================================================== Summary: Maestro3 driver does not work with Fedora Xen Kernels Description: maestro3.c contains the following check which causes the driver to fail to work when using Fedora Xen0 kernels: ----------------------------------------------------------------------------- /* check, if we can restrict PCI DMA transfers to 28 bits */ if (pci_set_dma_mask(pci, 0x0fffffff) < 0 || pci_set_consistent_dma_mask(pci, 0x0fffffff) < 0) { snd_printk(KERN_ERR "architecture does not support 28bit PCI busmaster DMA\n"); pci_disable_device(pci); return -ENXIO; } ----------------------------------------------------------------------------- Commenting out the lines: pci_disable_device(pci); return -ENXIO; causes the driver to load and seemingly work properly. Not sure what negative impact removing this check can have. ====================================================================== ---------------------------------------------------------------------- chrisw - 03-14-06 04:46 ---------------------------------------------------------------------- File this under kernel-xen in Fedora Bugzilla (it's a Xen issue). Also, please include the dmesg from bootup. It will show swiotlb info that's useful. Specifically, if the swiotlb is in use, and mapped up too high, it won't be able to handle 28-bit dma mask. ---------------------------------------------------------------------- xaoslaad - 03-15-06 14:06 ---------------------------------------------------------------------- Will file as you said, and leave the information you suggested.
