The emulation functions which supply default BlockDriver .bdrv_*() functions given another implemented .bdrv_*() function should not use public bdrv_*() interfaces. This patch ensures they invoke .bdrv_*() directly to avoid adding an extra layer of coroutine request processing and possibly entering an infinite loop.

We will unify block layer request processing across sync, aio, and coroutines and this means a .bdrv_co_*() emulation function should not call back into the public interface. There's no need here, just call .bdrv_aio_*() directly. The gory details: bdrv_co_io_em() cannot call back into the public bdrv_aio_*() interface since that will be handled using coroutines, which causes us to call into bdrv_co_io_em() again in an infinite loop :).

This commit adds support to the BlockDriverState type to keep track of devices' I/O status. There are three possible status: BDRV_IOS_OK (no error), BDRV_IOS_ENOSPC (no space error) and BDRV_IOS_FAILED (any other error). The distinction between no space and other errors is important because a management application may want to watch for no space in order to extend the space assigned to the VM and put it to run again. Qemu devices supporting the I/O status feature have to enable it explicitly by calling bdrv_iostatus_enable() _and_ have to be configured to stop the VM on errors (ie. werror=stop|enospc or rerror=stop). In case of multiple errors being triggered in sequence only the first one is stored. The I/O status is always reset to BDRV_IOS_OK when the 'cont' command is issued. Next commits will add support to some devices and extend the query-block/info block commands to return the I/O status information.

The alarm is a fully general one-shot time comparator, which will be usable under Linux as a hrtimer source. It's much more flexible than the RTC source available on real hardware. The wall clock allows the guest access to the host timekeeping. Much like the KVM wall clock source for other guests. Both are accessed via the PALcode Cserve entry point.

Currently there is no implementation for set-time-of-day rtas function, which causes the following warning "setting the clock failed (-1)" on the guest. This patch just creates this function, get the timedate diff and store in the papr environment, so that the correct value will be returned by get-time-of-day. In order to try it, just adjust the hardware time, run hwclock --systohc, so that, on when the system runs hwclock --hctosys, the value is correctly adjusted, i.e. the host time plus the timediff.

Paulo Bonzini changed the original spapr code, which manually assigned irq numbers for each virtual device, to allocate them automatically from the device initialization. That allowed spapr virtual devices to be constructed with -device, which is a good start. However, the way that patch worked doesn't extend nicely for the future when we want to support devices other than sPAPR VIO devices (e.g. virtio and PCI). This patch rearranges the irq allocation to be global across the sPAPR environment, so it can be used by other bus types as well.

While working on the emulation of the freescale p2010 (e500v2) I realized that there's no implementation of booke's timers features. Currently mpc8544 uses ppc_emb (ppc_emb_timers_init) which is close but not exactly like booke (for example booke uses different SPR).

When running with PR KVM, we need to set HIOR directly. Thankfully there is now a new interface to set registers individually so we can just use that and poke HIOR into the guest vcpu's HIOR register. While at it, this also sets SDR1 because -M pseries requires it to run. With this patch, -M pseries works properly with PR KVM. Signed-off-by: NAlexander Graf <agraf@suse.de>
