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>

qemu-kvm carries the IOAPIC base address in its v2 vmstate. We only support the default base address so far, and saving even that in the device state was rejected. Add a padding field to be able to read qemu-kvm's old state, but increase our version to 3, indicating that we are not saving a valid address. This also gives downstream the chance to change to stop evaluating the base_address and move to v3 as well.

When MSI is off, each interrupt needs to be bounced through the io thread when it's set/cleared, so vhost-net causes more context switches and higher CPU utilization than userspace virtio which handles networking in the same thread. We'll need to fix this by adding level irq support in kvm irqfd, for now disable vhost-net in these configurations. Added a vhostforce flag to force vhost-net back on. Signed-off-by: NMichael S.

The Ubuntu 10.10 gcc for ARM complains that we might be overrunning the cpu_irqs[][] array: silence this by correcting the bounds on the loop. (In fact we would not have overrun the array because bit MAX_PILS in pil_pending and irl_out will always be 0.) Also add a comment about why the loop's lower bound is OK.

Watch this: (qemu) drive_add 0 if=none (qemu) info block none0: type=hd removable=0 [not inserted] (qemu) drive_del none0 Segmentation fault (core dumped) add_init_drive() is confused about drive_init()'s failure modes, and cleans up when it shouldn't. This leaves the DriveInfo with member opts dangling. drive_del attempts to free it, and dies. drive_init() behaves as follows: * If it created a drive with media, it returns its DriveInfo. * If it created a drive without media, it clears *fatal_error and returns NULL. * If it couldn't create a drive, it sets *fatal_error and returns NULL. Of its three callers: * drive_init_func() is correct. * usb_msd_init() assumes drive_init() failed when it returns NULL. This is correct only because it always passes option "file", and "drive without media" can't happen then. * add_init_drive() assumes drive_init() failed when it returns NULL. This is incorrect. Clean up drive_init() to return NULL on failure and only on failure. Drop its parameter fatal_error.

Before, type & index were hidden in printf-like fmt, ... parameters, which get expanded into an option string. Rather inconvenient for uses later in this series.

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.

drive_init() picks the first free bus and unit number, unless the user specifies them. This isn't a good fit for the drive_add monitor command, because there we specify the controller by PCI address instead of using bus number set by drive_init(). scsi_hot_add() takes care to replace the unit number set by drive_init() by the real one, but it neglects to replace the bus number. Thus, bus/unit in DriveInfo may be bogus. Affects drive_get() and drive_get_max_bus(). I'm not aware of anything bad happening because of that; looks like by the time we're hot-plugging, the two functions aren't used anymore. Fix it anyway.

For some unknown reason, the MIPS kernel briefly changes the RTC to binary mode during boot, switch back to BCD mode and read the time. As the registers are updated only every second, they may still be in the old format when they are read. This patch forces a register update immediately after a format change (BCD/binary or 12/24H). This avoid long fsck during boot due to time wrap. Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>

Recent PowerPC kernel end up in kernel panic during boot in -nographic mode. In this mode the second serial port is used as the udbg console, and thus a few characters are sent on this port. This activates the tx interrupt flag, and later choke the Linux kernel, as it was not expecting such a flag to be set. The problem here comes from the fact that contrary to most devices the interrupt flags are only set if the interrupt is enabled. Quoting the datasheet: "If the corresponding IE bit is not set, the IP for that source of interrupt will never be set." This patch fixes that by enabling the interrupt flag only when the corresponding interrupt is enabled. Cc: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>
