[Qemu-devel] [PATCH 24/27] Implement PAPR virtual SCSI interface (ibmvscsi)

From: Ben Herrenschmidt This patch implements the infrastructure and hypercalls necessary for the PAPR specified Virtual SCSI interface. This is the normal method for providing (virtual) disks to PAPR partitions. Signed-off-by: Ben Herrenschmidt Signed-off-by: David Gibson --- Makefile.targe

[Qemu-devel] [PATCH 25/27] Add a PAPR TCE-bypass mechanism for the pSeries machine

From: Ben Herrenschmidt Usually, PAPR virtual IO devices use a virtual IOMMU mechanism, TCEs, to mediate all DMA transfers. While this is necessary for some sorts of operation, it can be complex to program and slow for others. This patch implements a mechanism for bypassing TCE translation, tre

[Qemu-devel] [PATCH 26/27] Implement PAPR VPA functions for pSeries shared processor partitions

Shared-processor partitions are those where a CPU is time-sliced between partitions, rather than being permanently dedicated to a single partition. qemu emulated partitions, since they are just scheduled with the qemu user process, behave mostly like shared processor partitions. In order to bette

[Qemu-devel] [PATCH 21/27] Implement TCE translation for sPAPR VIO

This patch implements the necessary infrastructure and hypercalls for sPAPR's TCE (Translation Control Entry) IOMMU mechanism. This is necessary for all virtual IO devices which do DMA (i.e. nearly all of them). Signed-off-by: Ben Herrenschmidt Signed-off-by: David Gibson --- hw/spapr.c |

[Qemu-devel] [PATCH 20/27] Add (virtual) interrupt to PAPR virtual tty device

Now that we have implemented the PAPR "xics" virtualized interrupt controller, we can add interrupts in PAPR VIO devices. This patch adds interrupt support to the PAPR virtual tty/console device. Signed-off-by: David Gibson --- hw/spapr.c |6 -- hw/spapr_vio.h |3 ++- hw/spapr_v

[Qemu-devel] [PATCH 07/27] Clean up slb_lookup() function

The slb_lookup() function, used in the ppc translation path returns a number of slb entry fields in reference parameters. However, only one of the two callers of slb_lookup() actually wants this information. This patch, therefore, makes slb_lookup() return a simple pointer to the located SLB entr

[Qemu-devel] [PATCH 10/27] Better factor the ppc hash translation path

Currently the path handling hash page table translation in get_segment() has a mix of common and 32 or 64 bit specific code. However the division is not done terribly well which results in a lot of messy code flipping between common and divided paths. This patch improves the organization, consoli

[Qemu-devel] [PATCH 23/27] Implement PAPR CRQ hypercalls

From: Ben Herrenschmidt This patch implements the infrastructure and hypercalls necessary for the PAPR specified CRQ (Command Request Queue) mechanism. This general request queueing system is used by many of the PAPR virtual IO devices, including the virtual scsi adapter. Signed-off-by: Ben Her

[Qemu-devel] [PATCH V3] floppy: save and restore DIR register

We need to keep DIR register unchanged across migration, but currently it depends on the media_changed flags from block layer. Since we do not save/restore it and the bdrv_open() called in dest node may set the media_changed flag when trying to open floppy image, guest driver may think the floppy h

Hi. SLIC table can be fed dynamically by utilize the existing fw_cfg interface. Something like this. (This requires your qemu patch.) This is just for showing the idea. thanks, diff --git a/src/acpi.c b/src/acpi.c index 6428d9c..e0815bd 100644 --- a/src/acpi.c +++ b/src/acpi.c @@ -627,6 +627,7 @@
