2014-11-14ahci: unify sglist preparationJohn Snow
The intent of this patch is to further unify the creation and deletion of the sglist used for all AHCI transfers, including emulated PIO, ATAPI R/W, and native DMA R/W. By replacing ahci_start_transfer's call to ahci_populate_sglist with ahci_dma_prepare_buf, we reduce the number of direct calls where we manipulate the scatter-gather list in the AHCI code. To make this switch, the constant "0" passed as an offset in ahci_dma_prepare_buf is adjusted to use io_buffer_offset. For DMA pathways, this has no effect: io_buffer_offset is always updated to 0 at the beginning of a DMA transfer loop regardless. DMA pathways through ide_dma_cb() update the io_buffer_offset accordingly, and for circumstances where we might make several trips through this loop, this may actually correct a design flaw. For PIO pathways, the newly updated ahci_dma_prepare_buf will now prepare the sglist at the correct offset. It will also set io_buffer_size, but this is not used in the cmd_read_pio or cmd_write_pio pathways.

2014-11-14ide: repair PIO transfers for cases where nsector > 1John Snow
Currently, for emulated PIO transfers through the AHCI device, any attempt made to request more than a single sector's worth of data will result in the same sector being transferred over and over. For example, if we request 8 sectors via PIO READ SECTORS, the AHCI device will give us the same sector eight times. This patch adds offset tracking into the PIO pathways so that we can fulfill these requests appropriately.

2014-11-14ahci: Fix byte count regression for ATAPI/PIOJohn Snow
This patch fixes a regression caused by commit 659142ecf71a0da240ab0ff7cf929ee25c32b9bc. The problem occurs when we wish to return early from the ahci_start_transfer function, but are now updating the transferred byte count in the AHCI command header via ahci_commit_buf. This will cause problems in the Windows 8 installer. Don't update the byte count in the command header for the transmission of ATAPI packets: These commands will distort the final byte count of the actual data payload. The call to ahci_commit_buf remains in the "out" portion of the call in order to clean up the sglist. The byte count is maintained by forcing size to be 0.

Old BIOSes left some padding by mistake after the req_size/resp_size. New QEMU does not like it, thinking it is a bidirectional command. As a workaround, we can check if the ANY_LAYOUT bit is set; if not, we always consider the first buffer as the virtio-scsi request/response, because, back when QEMU did not support ANY_LAYOUT, it expected the payload to start at the second element of the iovec.

2014-11-04PPC: e500: Support dynamically spawned sysbus devicesAlexander Graf
For e500 our approach to supporting dynamically spawned sysbus devices is to create a simple bus from the guest's point of view within which we map those devices dynamically. We allocate memory regions always within the "platform" hole in address space and map IRQs to predetermined IRQ lines that are reserved for platform device usage. This maps really nicely into device tree logic, so we can just tell the guest about our virtual simple bus in device tree as well. Signed-off-by: Alexander Graf <agraf@suse.de>
2014-11-04sysbus: Add new platform bus helper deviceAlexander Graf
We need to support spawning of sysbus devices dynamically via the command line. The easiest way to represent these dynamically spawned devices in the guest's memory and IRQ layout is by preallocating some space for dynamic sysbus devices. This is what the "platform bus" device does. It is a sysbus device that exports a configurably sized MMIO region and a configurable number of IRQ lines. When this device encounters sysbus devices that have been dynamically created and not manually wired up, it dynamically connects them to its own pool of resources. The machine model can then loop through all of these devices and create a guest configuration (device tree) to make them visible to the guest. Signed-off-by: Alexander Graf <agraf@suse.de>
2014-11-04sysbus: Expose MMIO enumeration helperAlexander Graf
Sysbus devices have a range of MMIO regions they expose. The exact number of regions is device specific and internal information to the device model.

2014-11-04sysbus: Expose IRQ enumeration helpersAlexander Graf
Sysbus devices can get their IRQ lines connected to other devices. It is possible to figure out which IRQ line a connection is on and whether a sysbus device even provides an IRQ connector at a specific offset. This patch exposes helpers to make this information publicly accessible. We will need it for the platform bus dynamic sysbus enumeration. Signed-off-by: Alexander Graf <agraf@suse.de>
2014-11-04sysbus: Make devices spawnable via -deviceAlexander Graf
Now that we can properly map sysbus devices that haven't been connected to something forcefully by C code, we can allow the -device command line option to spawn them. For machines that don't implement dynamic sysbus assignment in their board files we add a new bool "has_dynamic_sysbus" to the machine class. When that property is false (default), we bail out when we see dynamically spawned sysbus devices, like we did before. Signed-off-by: Alexander Graf <agraf@suse.de>
2014-11-04sysbus: Add dynamic sysbus device searchAlexander Graf

2014-11-04spapr: Cleanup machine naming conventions, and prepare for 2.2 releaseDavid Gibson
As of qemu-2.1, spapr/pseries, has a set of versioned machine classes to represent the machine type as it appeared to the guest in different qemu versions. This allows for safe migration of guests between current and future qemu versions. However, these are organized a bit differently from those for PC: on PC, the default plain "pc" machine type is just an alias for the most recent versioned machine type. In sPAPR, it names the base machine class from which the versioned types are derived. The PC approach is preferable; it makes it clearer which explicit version is the current one. Additionally updating the "current" machine as the base class makes it even more likely than otherwise to incorrectly alter the versioned machines' behaviour when updating the current machine. Therefore this patch changes sPAPR to the PC approach - the base class becomes abstract, and plain "pseries" becomes an alias for the most recent versioned machine class. Since qemu-2.1 is now released, we also create a new pseries-2.2 machine type, to incorporate changes during this development cycle (for now it is identical to pseries-2.1).

2014-11-03target-i386: Rename KVM auto-feature-enable compat functionEduardo Habkost
The x86_cpu_compat_disable_kvm_features() name was a bit confusing, as it won't forcibly disable the feature for all CPU models (i.e. add it to kvm_default_unset_features), but it will instead turn off the KVM auto-enabling of the feature (i.e. remove it from kvm_default_features), meaning the feature may still be enabled by default in some CPU models).
