[S390] kvm: use console_initcall() to initialize s390 virtio console

2009-09-11T08:29:52Z

Use a console_initcall() to initialize the s390 virtio console and clean up s390 console initialization in setup.c. Signed-off-by: Hendrik Brueckner Tested-by: Christian Borntraeger Signed-off-by: Martin Schwidefsky

virtio: find_vqs/del_vqs virtio operations

2009-06-12T12:46:36Z

This replaces find_vq/del_vq with find_vqs/del_vqs virtio operations, and updates all drivers. This is needed for MSI support, because MSI needs to know the total number of vectors upfront. Signed-off-by: Michael S. Tsirkin Signed-off-by: Rusty Russell (+ lguest/9p compile fixes)

virtio: add names to virtqueue struct, mapping from devices to queues.

2009-06-12T12:46:36Z

Add a linked list of all virtqueues for a virtio device: this helps for debugging and is also needed for upcoming interface change. Also, add a "name" field for clearer debug messages. Signed-off-by: Rusty Russell

s390: remove s390_root_dev_*()

2009-01-06T18:44:34Z

Replace s390_root_dev_register() with root_device_register() etc. [Includes fix from Cornelia Huck] Signed-off-by: Mark McLoughlin Cc: Cornelia Huck Signed-off-by: Greg Kroah-Hartman

kvm-s390: implement config_changed for virtio on s390

2008-12-29T22:56:11Z

This patch implements config_changed for the s390 virtio transport. We use the least significant bit of the interrupt parameter field to decide, if this interrupt should call the virtio virtqueue callback or the config_changed callback. This method is compatible with old host and guest code. Old 64 bit guests will not check the bit and trigger a harmless additional vring_interrupt call. Old host code will never set this bit, this is also safe. This patch also takes care of a potential future 31 bit virtio transport for s390. On 31 bit _LC_PFAULT_INTPARM and __LC_EXT_PARAMS are identical. We exploit the alignment of the token and fold the change bit into the lsb of the token itself.

virtio: hand virtio ring alignment as argument to vring_new_virtqueue

2008-12-29T22:56:03Z

This allows each virtio user to hand in the alignment appropriate to their virtio_ring structures. Signed-off-by: Rusty Russell Acked-by: Christian Borntraeger

virtio: use KVM_S390_VIRTIO_RING_ALIGN instead of relying on pagesize

2008-12-29T22:56:03Z

This doesn't really matter, since s390 pagesize is 4k anyway. Signed-off-by: Rusty Russell Acked-by: Christian Borntraeger

[S390] kvm_s390: Fix oops in virtio device detection with "mem="

2008-11-14T17:18:52Z

The current virtio model on s390 has the descriptor page above the main memory. The guest virtio detection will oops if the mem= parameter is used to reduce/change the memory size. We have to use real_memory_size instead of max_pfn to detect the virtio descriptor pages. Signed-off-by: Christian Borntraeger

[S390] Use s390_root_dev_* in kvm_virtio.

2008-10-10T19:33:51Z

No need to define a static device for the kvm_s390 root device, just use s390_root_dev_register(). This is needed for the bus_id rework Acked-by: Carsten Otte Cc: Kay Sievers Signed-off-by: Cornelia Huck Signed-off-by: Greg Kroah-Hartman Signed-off-by: Martin Schwidefsky

[S390] virtio console: fix section mismatch warning.

2008-08-01T14:39:35Z

Fix these two false positive warnings: WARNING: vmlinux.o(.text+0x2e1cc4): Section mismatch in reference from the function s390_virtio_console_init() to the function .init.text:early_put_chars() The function s390_virtio_console_init() references the function __init early_put_chars(). This is often because s390_virtio_console_init lacks a __init annotation or the annotation of early_put_chars is wrong. WARNING: vmlinux.o(.text+0x2e1cd0): Section mismatch in reference from the function s390_virtio_console_init() to the function .init.text:virtio_cons_early_init() The function s390_virtio_console_init() references the function __init virtio_cons_early_init(). This is often because s390_virtio_console_init lacks a __init annotation or the annotation of virtio_cons_early_init is wrong.
