2020-05-13bus: vexpress-config: Merge vexpress-syscfg into vexpress-configRob Herring3-290/+0
The only thing that vexpress-syscfg does is provide a regmap to vexpress-config bus child devices. There's little reason to have 2 components for this. The current structure with initcall ordering requirements makes turning these components into modules more difficult. So let's start to simplify things and merge vexpress-syscfg into vexpress-config. There's no functional change in this commit and it's still separate components until subsequent commits.

This caused a regression for mei_me_synchronize_irq() waiting for the wrong irq number. On my laptop this causes a hang on shutdown. Fix the issue by storing the irq number after enabling MSI.

2020-04-20vhost: disable for OABIMichael S. Tsirkin1-1/+1
vhost is currently broken on the some ARM configs. The reason is that the ring element addresses are passed between components with different alignments assumptions. Thus, if guest selects a pointer and host then gets and dereferences it, then alignment assumed by the host's compiler might be greater than the actual alignment of the pointer. compiler on the host from assuming pointer is aligned. This actually triggers on ARM with -mabi=apcs-gnu - which is a deprecated configuration. With this OABI, compiler assumes that all structures are 4 byte aligned - which is stronger than virtio guarantees for available and used rings, which are merely 2 bytes. Thus a guest without -mabi=apcs-gnu running on top of host with -mabi=apcs-gnu will be broken. The correct fix is to force alignment of structures - however that is an intrusive fix that's best deferred until the next release. We didn't previously support such ancient systems at all - this surfaced after vdpa support prompted removing dependency of vhost on VIRTULIZATION. So for now, let's just add something along the lines of depends on !ARM || AEABI to the virtio Kconfig declaration, and add a comment that it has to do with struct member alignment. Note: we can't make VHOST and VHOST_RING themselves have a dependency since these are selected. Add a new symbol for that. We should be able to drop this dependency down the road.

2020-04-01vhost: refine vhost and vringh kconfigJason Wang1-4/+0
Currently, CONFIG_VHOST depends on CONFIG_VIRTUALIZATION. But vhost is not necessarily for VM since it's a generic userspace and kernel communication protocol. Such dependency may prevent archs without virtualization support from using vhost. To solve this, a dedicated vhost menu is created under drivers so CONIFG_VHOST can be decoupled out of CONFIG_VIRTUALIZATION. While at it, also squash Kconfig.vringh into vhost Kconfig file. This avoids the trick of conditional inclusion from VOP or CAIF. Then it will be easier to introduce new vringh users and common dependency for both vringh and vhost.

When moving from manual to automatic power management mode in GOYA, the driver didn't correctly place the device in LOW power mode.
