Hi, I saw from the CVS ChangeLog that ALSA is moving away from the deprecated virt_to_bus() to the new pci_allocate_consistent() system calls. Unfortunately, this is causing problems for my ISA DMA sound driver (CS4231 / MPU401 based). I have currently "fixed" things by #undef-ing the ISA_USE_PCI_ALLOC in core/pcm_memory.c. Once I do this, I get sound out of my speakers again.
My soundcard also needs a DMA-able buffer so that it can upload its firmware. Previously, I used snd_malloc_pages(), and I tried changing this to snd_malloc_isa_pages(). However, you don't export this function, and even when I cut-and-pasted it into the source file, the firmware wouldn't upload until I used the virt_to_bus()-based compatibility version. It would probably be a good idea to export the following functions: snd_malloc_pci_pages() snd_malloc_isa_pages() snd_free_pci_pages() snd_free_isa_pages() Does anyone have any idea why pci_allocate_consistent() isn't working here, please?
