Hi,Alexander Graf.
I am very glad you noticed my patch about ahci.I love qemu just like I love linux.I wish I could do much more work on
qemu development.
I had cloned qemu from master branch,add my patch into it,and tested ahci on
i386 softmmu.
If anyone is interested on ahci,you can test my patch like this:
git-clone -ls git://git.savannah.nongnu.org/qemu
patch -p1 -i 0001-add-ahci-support-into-qemu-only-support-sata-disk.patch
patch -p1 -i 0002-add-ahci-device-into-i386-pc-just-for-test.patch
The last submission was missing the qemu "glue", but this one looks complete. Nonetheless the old one was working fine
enough.
./configure --target-list=i386-softmmu
make
dd if=/dev/zero of=/tmp/disk bs=1M count=100
./i386-softmmu/qemu -cdrom KNOPPIX_V6.0.1CD-2009-02-08-EN.iso -boot d -drive
if=sd,file=/tmp/disk
After linux boot,you will find a ahci device named sda.
Now this patch only support sata disk.
Most ahci registers and operations which are not necessary on linux are ignored.
Now this patch support disk identify,dma read,dma write,ignore other opertions.
Do you intent to work on this and complet the support?
There are also some minor changes needed like moving PCI_VENDOR_MYDEVICE
and PCI_PRODUCT_MYDEVICE to pci.h and others.
Did you use the Intel document #301473 for reference?
By the way how you send patch to mail list?
Try "git send-email".

Sebastian
