Different AHCI controllers have a different number of ports, so the core shouldn't care about the amount of ports available. This patch makes the number of ports available to the AHCI core runtime configurable, allowing us to have multiple different AHCI implementations with different amounts of ports.

The ahci code was missing its soft reset functionality. This wasn't really an issue for Linux guests, but Windows gets confused when the controller doesn't reset when it tells it so. Using this patch I can now successfully boot Windows 7 from AHCI using AHCI enabled SeaBIOS. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

The drive sends a d2h init fis on initialization. Usually, the guest doesn't receive fises yet at that point though, so the delivery is deferred. Let's reflect that by sending the init fis on fis receive enablement. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

Sebastian's patch already did a pretty good job at splitting up ICH-9 AHCI code and the AHCI core. We need some more though. Copyright was missing, the lspci dump belongs to ICH-9, we don't need the AHCI core to have its own qdev device duplicate. So let's split them a bit more in this patch, making things easier to read an understand. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

There are multiple ahci devices out there. The currently implemented ich-9 is only one of the many. So let's split that one out into a separate file to stress the difference.

Before commit 622b520f, index=12 meant bus=1,unit=5. Since the commit, it means bus=0,unit=12. The drive is created, but not the guest device. That's because the controllers we use with if=scsi drives (lsi53c895a and esp) support only 7 units, and scsi_bus_legacy_handle_cmdline() ignores drives with unit numbers exceeding that limit. Changing the mapping of index to bus, unit is a regression. Breaking -drive invocations that used to work just makes it worse. Revert the part of commit 622b520f that causes this, and clean up some. Note that the fix only affects if=scsi. You can still put more than 7 units on a SCSI bus with -device & friends.

The len and is_write arguments to cpu_physical_memory_unmap() were swapped. This patch changes calls to use the correct argument ordering. Signed-off-by: NStefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

This patch adds an emulation layer for an ICH-9 AHCI controller. For now this controller does not do IDE legacy emulation. It is a pure AHCI controller. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NKevin Wolf <kwolf@redhat.com>
