#6922 closed bug (fixed)

OpenSound-232d0de71550 KDL's on boot (possible mtrr issue?)

Reported by: mmadia Owned by: mmu_man
Priority: normal Milestone: R1
Component: Drivers/Audio/OpenSound Version: R1/Development
Keywords: Cc:
Blocked By: Blocking: #6849
Platform: All


This ticket is being split off from my comments made in #6849, as there may be possible confusion between the various OpenSound packages (which are not part of build/jam/OptionalPackages, due to concerns of known issues).

This package of opensound-232d0de71550 was built on hrev39567 with GCC4. It contains extra dprintf()'s to help pinpoint the exact location of failure.

The failure occurs when

  1. The above OpenSound package is installed
  2. /boot/system/add-ons/kernel/drivers/dev/audio/* is archived and the original files are removed
  3. On reboot, oss detects the hd audio chipset and triggers a KDL.

The failure is in os_beos.c oss_map_pci_mem()

oss_map_pci_mem (oss_device_t * osdev, int nr, int phaddr, int size)
  status_t err;
  void *va = NULL;
  FENTRYA("%p,%d,%u,%d", osdev, nr, phaddr, size);
  //XXX:align phaddr ?
  /* round up to page size */
  size += B_PAGE_SIZE - 1;
  size &= ~(B_PAGE_SIZE - 1);
  err = map_physical_memory(OSS_PCI_AREA_NAME, (void *)phaddr, size,
                            B_ANY_KERNEL_BLOCK_ADDRESS, 0, &va);
  dprintf("oss_map_pci_mem() -- past map_physical_memory\n");
  if (err < B_OK)
    va = NULL;
  return (caddr_t)va;

Blocking: 6849 added

Setting this ticket as a blocker for #6849, as the current OpenSound package in build/jam/OptionalPackages ( does not contain the code to allow co-existence with native drivers.

The current 4.2_git-2 package has a fix for this (the KDL on 64bit). I thought I upstreamed it but it doesn't seem to be in their git tree yet.

Please test on a recent nightly.
