[Qemu-devel] [PATCH V2] DMA timeouts running a FreeBSD guest

[Carlo Marcelo Arenas Belon]

Greetings,

the following patch moves the initialization for bm->cur_addr from the
ide_dma_start function to bmdma_addr_writel, so that it is set in sync 
with the call to set the destination address for DMA (bm->addr) and to 
avoid timeouts in guests that set this address after they have called 
the READ_DMA command (FreeBSD).

the final package has been tested with the following guests :

  FreeBSD 6.2 (amd64 and i386)
  FreeBSD 5.3 (i386)
  Fedora Core 6 (i386)
  Gentoo Linux 2006.1 (i386)
  NexentaOS Alpha 6 (amd64)
  OpenSolaris Nevada b55b (amd64)
  OpenBSD 4.0 (amd64 and i386)
  Windows 2000 (i386)
