[Qemu-devel] [PATCH 0/6] [AHCI]resend all patches to add ahci support in

When ahci init ,driver will send ATA_SRST command,ahci device report device 
type through port's sig register.
Ahci disk lookup change from IF_SD to IF_SCSI now,because IF_SD does not 
support cdrom media.
I just copy ide_atapi_cmd from hw/ide/core.c into hw/ahci.c,change a 
little,then the cdrom can be identified,and read by os.
If qemu can change dma_buf_prepare,dma_buf_rw,dma_buf_commit to a function 
pointer in BMDMAState,then I can rewrite three functions to support ahci's 
prtd,because it is different from ide's.

test a sata disk like this:
./i386-softmmu/qemu -cdrom KNOPPIX_V6.0.1CD-2009-02-08-EN.iso -drive 
if=scsi,file=/tmp/disk
test a sata cd like this:
./i386-softmmu/qemu -cdrom KNOPPIX_V6.0.1CD-2009-02-08-EN.iso -drive 
if=scsi,media=cdrom,file=KNOPPIX_V6.0.1CD-2009-02-08-EN.iso

QiaoChong (5):
  add ahci support into qemu,only support sata disk.
  add ahci device into i386 pc just for test.
  add  WIN_STANDBYNOW1 process into ahci.
  ahci pci ids  into pci_ids.h,add warning messages.
  add cdrom support for ahci.

Sebastian Herbszt (1):
  fix port count,cap and version etc to ahci.
