* q35: document gigabyte_alignMichael S. Tsirkin2014-01-261-0/+13

* q35: gigabyte alignment for ramGerd Hoffmann2014-01-261-2/+5
| | | | | | | | | | | | | Map 2G (q35) of memory below 4G, so the RAM pieces are nicely aligned to gigabyte borders. Keep old memory layout for (a) old machine types and (b) in case all memory fits below 4G and thus we don't have to split RAM into pieces in the first place. The later makes sure this change doesn't take away memory from 32bit guests. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
* acpi: Fix PCI hole handling on build_srat()Eduardo Habkost2014-01-261-5/+5
| | | | | | | | | | | | | | The original SeaBIOS code used the RamSize variable, that was used by SeaBIOS for the size of RAM below 4GB, not for all RAM. When copied to QEMU, the code was changed to use the full RAM size, and this broke the build_srat() code that handles the PCI hole. Change build_srat() to use ram_size_below_4g instead of ram_size, to restore the original behavior from SeaBIOS. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Michael S.

* hw/pci: fix error flow in pci multifunction initMarcel Apfelbaum2014-01-261-10/+10
| | | | | | | | | | | | | | | Scenario: - There is a non multifunction pci device A on 00:0X.0. - Hot-plug another multifunction pci device B at 00:0X.1. - The operation will fail of course. - Try to hot-plug the B device 2-3 more times, qemu will crash. Reason: The error flow leaves the B's address space into global address spaces list, but the device object is freed. Fixed that.

* acpi-build: enable hotplug for PCI bridgesMichael S. Tsirkin2014-01-263-94/+297
| | | | | | | | | | | | | | | | | | | This enables support for device hotplug behind pci bridges. Bridge devices themselves need to be pre-configured on qemu command line. Design: - at machine init time, assign "bsel" property to bridges with hotplug support - dynamically (At ACPI table read) generate ACPI code to handle hotplug events for each bridge with "bsel" property Note: ACPI doesn't support adding or removing bridges by hotplug. We detect and prevent removal of bridges by hotplug, unless they were added by hotplug previously (and so, are not described by ACPI). Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

| | | | | | | | | | | | | | | | | | | | Add ACPI based PCI hotplug library with bridge hotplug support. Design - each bus gets assigned "bsel" property. - ACPI code writes this number to a new BNUM register, then uses existing UP/DOWN registers to probe slot status; to eject, write number to BNUM register, then slot into existing EJ. The interface is actually backwards-compatible with existing PIIX4 ACPI (though not migration compatible). This is split out from PIIX4 codebase so we can reuse it for Q35 as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SeaBIOS waits for LUN0 to respond to the TEST UNIT READY command in order to decide whether it should part of the boot sequence. If LUN0 does not respond to the command, boot is delayed by up to 5 seconds. This currently happens when there is no LUN0 on a target. Fix that by adding a trivial implementation of the command.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is still a small window that occurs when a cancel I/O affects an asynchronous I/O operation that hasn't started. In other words, when the residual data length equals the expected data length. Today, the routine virtio_scsi_command_complete fails because the VirtIOSCSIReq pointer (from the hba_private field in SCSIRequest) was cleared earlier when virtio_scsi_complete_req was called by the virtio_scsi_request_cancelled routine. As a result, the virtio_scsi_command_complete routine needs to simply return when it is processing a SCSIRequest block that was marked canceled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux prefers WRITE SAME to UNMAP if the limits are zero, and WRITE SAME does not discard anything unless the device can guarantee that the resulting block is zero. Setting the maximum unmap block and descriptor counts to non-zero makes Linux choose UNMAP and fixes thin provisioning on glusterfs. While the maximum unmap block count can have some effect on performance, the (suggested) maximum number of descriptors is not particularly important so I didn't add a customization option. SCSI drivers are used to online firmware updates so I'm not yet adding versioning support for SCSI, but we're probably getting close to the point when it's worth thinking about it.

We used to try and make addresses aligned so they are easier to cover with MTRRs, but since they are cosmetic on KVM, this is probably not worth worrying about. Of course the firmware can use less than that. Leaving space unused is no problem, mapping pci bars outside the hole causes problems though.

| * | | qdev: switch reset to post-orderPaolo Bonzini2013-12-233-22/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Post-order is the only sensible direction for the reset signals. For example, suppose pre-order is used and the parent has some data structures that cache children state (for example a list of active requests). When the reset method is invoked on the parent, these caches could be in any state. If post-order is used, on the other hand, these will be in a known state when the reset method is invoked on the parent. This change means that it is no longer possible to block the visit of the devices, so the callback is changed to return void. This is not a problem, because PCI was returning 1 exactly in order to achieve the same ordering that this patch implements. PCI can then rely on the qdev core having sent a "reset signal" (whatever that means) to the device, and only do the PCI-specific initialization with pci_do_device_reset.

| * | | qdev: allow both pre- and post-order vists in qdev walking functionsPaolo Bonzini2013-12-231-12/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Resetting should be done in post-order, not pre-order. However, qdev_walk_children and qbus_walk_children do not allow this. Fix it by adding two extra arguments to the functions. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
