2022-09-02vdpa: Delete CVQ migration blockerEugenio Pérez
We can restore the device state in the destination via CVQ now. Remove the migration blocker. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vdpa: Add virtio-net mac address via CVQ at startEugenio Pérez
This is needed so the destination vdpa device see the same state a the guest set in the source. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vhost_net: add NetClientState->load() callbackEugenio Pérez
It allows per-net client operations right after device's successful start. In particular, to load the device status. Vhost-vdpa net will use it to add the CVQ buffers to restore the device status. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vdpa: extract vhost_vdpa_net_cvq_add from vhost_vdpa_net_handle_ctrl_availEugenio Pérez
So we can reuse it to inject state messages. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> -- v7: * Remove double free error v6: * Do not assume in buffer sent to the device is sizeof(virtio_net_ctrl_ack) v5: * Do not use an artificial !NULL VirtQueueElement * Use only out size instead of iovec dev_buffers for these functions. Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vdpa: Move command buffers map to start of net deviceEugenio Pérez
As this series will reuse them to restore the device state at the end of a migration (or a device start), let's allocate only once at the device start so we don't duplicate their map and unmap. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vdpa: add net_vhost_vdpa_cvq_info NetClientInfoEugenio Pérez
Next patches will add a new info callback to restore NIC status through CVQ. Since only the CVQ vhost device is needed, create it with a new NetClientInfo. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vhost_net: Add NetClientInfo stop callbackEugenio Pérez
Used by the backend to perform actions after the device is stopped. In particular, vdpa net use it to unmap CVQ buffers to the device, cleaning the actions performed in prepare(). Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vhost_net: Add NetClientInfo start callbackEugenio Pérez
This is used by the backend to perform actions before the device is started. In particular, vdpa net use it to map CVQ buffers to the device, so it can send control commands using them. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vhost: Do not depend on !NULL VirtQueueElement on vhost_svq_flushEugenio Pérez
Since QEMU will be able to inject new elements on CVQ to restore the state, we need not to depend on a VirtQueueElement to know if a new element has been used by the device or not. Instead of check that, check if there are new elements only using used idx on vhost_svq_flush. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vhost: Delete useless read memory barrierEugenio Pérez
As discussed in previous series [1], this memory barrier is useless with the atomic read of used idx at vhost_svq_more_used. Deleting it. [1] https://lists.nongnu.org/archive/html/qemu-devel/2022-07/msg02616.html Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vhost: use SVQ element ndescs instead of opaque data for desc validationEugenio Pérez
Since we're going to allow SVQ to add elements without the guest's knowledge and without its own VirtQueueElement, it's easier to check if an element is a valid head checking a different thing than the VirtQueueElement. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vhost: stop transfer elem ownership in vhost_handle_guest_kickEugenio Pérez
It was easier to allow vhost_svq_add to handle the memory. Now that we will allow qemu to add elements to a SVQ without the guest's knowledge, it's better to handle it in the caller. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vdpa: Use ring hwaddr at vhost_vdpa_svq_unmap_ringEugenio Pérez
Reduce code duplication. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vhost: Always store new kick fd on vhost_svq_set_svq_kick_fdEugenio Pérez
We can unbind twice a file descriptor if we call twice vhost_svq_set_svq_kick_fd because of this. Since it comes from vhost and not from SVQ, that file descriptor could be a different thing that guest's vhost notifier. Likewise, it can happens the same if a guest start and stop the device multiple times. Reported-by: Lei Yang <leiyang@redhat.com> Fixes: dff4426fa6 ("vhost: Add Shadow VirtQueue kick forwarding capabilities") Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vdpa: Make SVQ vring unmapping return voidEugenio Pérez
Nothing actually reads the return value, but an error in cleaning some entries could cause device stop to abort, making a restart impossible. Better ignore explicitely the return value. Reported-by: Lei Yang <leiyang@redhat.com> Fixes: 34e3c94eda ("vdpa: Add custom IOTLB translations to SVQ") Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vdpa: Remove SVQ vring from iova_tree at shutdownEugenio Pérez
Although the device will be reset before usage, the right thing to do is to clean it. Reported-by: Lei Yang <leiyang@redhat.com> Fixes: 34e3c94eda ("vdpa: Add custom IOTLB translations to SVQ") Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02util: accept iova_tree_remove_parameter by valueEugenio Pérez
It's convenient to call iova_tree_remove from a map returned from iova_tree_find or iova_tree_find_iova. With the current code this is not possible, since we will free it, and then we will try to search for it again. Fix it making accepting the map by value, forcing a copy of the argument. Not applying a fixes tag, since there is no use like that at the moment. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vdpa: do not save failed dma maps in SVQ iova treeEugenio Pérez
If a map fails for whatever reason, it must not be saved in the tree. Otherwise, qemu will try to unmap it in cleanup, leaving to more errors. Fixes: 34e3c94eda ("vdpa: Add custom IOTLB translations to SVQ") Reported-by: Lei Yang <leiyang@redhat.com> Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-09-02vdpa: Skip the maps not in the iova treeEugenio Pérez
Next patch will skip the registering of dma maps that the vdpa device rejects in the iova tree. We need to consider that here or we cause a SIGSEGV accessing result.

2022-08-31ppc/ppc4xx: Introduce a DCR device modelCédric Le Goater
The Device Control Registers (DCR) of on-SoC devices are accessed by software through the use of the mtdcr and mfdcr instructions. These are converted in transactions on a side band bus, the DCR bus, which connects the on-SoC devices to the CPU. Ideally, we should model these accesses with a DCR namespace and DCR memory regions but today the DCR handlers are installed in a DCR table under the CPU. Instead, introduce a little device model wrapper to hold a CPU link and handle registration of DCR handlers. The DCR device inherits from SysBus because most of these devices also have MMIO regions and/or IRQs. Being a SysBusDevice makes things easier to install the device model in the overall SoC.

Drop the use of ppc4xx_init() and duplicate a bit of code related to clocks in the SoC realize routine. We will clean that up in the following patches. ppc_dcr_init() simply allocates default DCR handlers for the CPU. Maybe this could be done in model initializer of the CPU families needing it.

It is an initial model to start QOMification of the PPC405 board. QOM'ified devices will be reintroduced one by one. Start with the memory regions, which name prefix is changed to "ppc405". Also, initialize only one RAM bank. The second bank is a dummy one (zero size) which is here to match the hard coded number of banks in ppc405ep_init().
