iommufd_ctx is stored in vfio_device for emulated devices per bind_iommufd. However, as iommufd_access is created in bind, no more need to stored it since iommufd_access implicitly stores it.

2023-03-31iommufd: Create access in vfio_iommufd_emulated_bind()Nicolin Chen1-1/+2
There are needs to created iommufd_access prior to have an IOAS and set IOAS later. Like the vfio device cdev needs to have an iommufd object to represent the bond (iommufd_access) and IOAS replacement. Moves the iommufd_access_create() call into vfio_iommufd_emulated_bind(), making it symmetric with the __vfio_iommufd_access_destroy() call in the vfio_iommufd_emulated_unbind(). This means an access is created/destroyed by the bind()/unbind(), and the vfio_iommufd_emulated_attach_ioas() only updates the access->ioas pointer. Since vfio_iommufd_emulated_bind() does not provide ioas_id, drop it from the argument list of iommufd_access_create(). Instead, add a new access API iommufd_access_attach() to set the access->ioas pointer. Also, set vdev->iommufd_attached accordingly, similar to the physical pathway.

2023-03-31driver core: create class_is_registered()Greg Kroah-Hartman1-0/+1
Some classes (i.e. gpio), want to know if they have been registered or not, and poke around in the class's internal structures to try to figure this out. Because this is not really a good idea, provide a function for classes to call to try to figure this out. Note, this is racy as the state of the class could change at any moment in time after the call is made, but as usually a class only wants to know if it has been registered yet or not, it should be fairly safe to use, and is just as safe as the previous "poke at the class internals" check was. Move the gpiolib code to use this function as proof that it works properly.

2023-03-30dm: split discards further if target sets max_discard_granularityMike Snitzer2-2/+8
The block core (bio_split_discard) will already split discards based on the 'discard_granularity' and 'max_discard_sectors' queue_limits. But the DM thin target also needs to ensure that it doesn't receive a discard that spans a 'max_discard_sectors' boundary. Introduce a dm_target 'max_discard_granularity' flag that if set will cause DM core to split discard bios relative to 'max_discard_sectors'. This treats 'discard_granularity' as a "min_discard_granularity" and 'max_discard_sectors' as a "max_discard_granularity".

2023-03-30KVM: arm64: nv: timers: Support hyp timer emulationMarc Zyngier2-2/+8
Emulating EL2 also means emulating the EL2 timers. To do so, we expand our timer framework to deal with at most 4 timers. At any given time, two timers are using the HW timers, and the two others are purely emulated. The role of deciding which is which at any given time is left to a mapping function which is called every time we need to make such a decision.

2023-03-30KVM: arm64: nv: timers: Add a per-timer, per-vcpu offsetMarc Zyngier1-0/+5
Being able to set a global offset isn't enough. With NV, we also need to a per-vcpu, per-timer offset (for example, CNTVCT_EL0 being offset by CNTVOFF_EL2). Use a similar method as the VM-wide offset to have a timer point to the shadow register that contains the offset value.

2023-03-30KVM: arm64: timers: Move the timer IRQs into arch_timer_vm_dataMarc Zyngier1-4/+14
Having the timer IRQs duplicated into each vcpu isn't great, and becomes absolutely awful with NV. So let's move these into the per-VM arch_timer_vm_data structure. This simplifies a lot of code, but requires us to introduce a mutex so that we can reason about userspace trying to change an interrupt number while another vcpu is running, something that wasn't really well handled so far.

2023-03-30KVM: arm64: timers: Abstract per-timer IRQ accessMarc Zyngier1-0/+2
As we are about to move the location of the per-timer IRQ into the VM structure, abstract the location of the IRQ behind an accessor. This will make the repainting sligntly less painful.

2023-03-30KVM: arm64: timers: Rationalise per-vcpu timer initMarc Zyngier1-1/+0
The way we initialise our timer contexts may be satisfactory for two timers, but will be getting pretty annoying with four. Cleanup the whole thing by removing the code duplication and getting rid of unused IRQ configuration elements.

2023-03-30KVM: arm64: timers: Allow userspace to set the global counter offsetMarc Zyngier1-0/+3
And this is the moment you have all been waiting for: setting the counter offset from userspace. We expose a brand new capability that reports the ability to set the offset for both the virtual and physical sides. In keeping with the architecture, the offset is expressed as a delta that is substracted from the physical counter value. Once this new API is used, there is no going back, and the counters cannot be written to to set the offsets implicitly (the writes are instead ignored).

2023-03-30KVM: arm64: timers: Use CNTPOFF_EL2 to offset the physical timerMarc Zyngier2-0/+3
With ECV and CNTPOFF_EL2, it is very easy to offer an offset for the physical timer. So let's do just that. Nothing can set the offset yet, so this should have no effect whatsoever (famous last words...).

2023-03-30KVM: arm64: timers: Use a per-vcpu, per-timer accumulator for fractional nsMarc Zyngier1-0/+1
Instead of accumulating the fractional ns value generated every time we compute a ns delta in a global variable, use a per-vcpu, per-timer variable. This keeps the fractional ns local to the timer instead of contributing to any odd, unrelated timer.

2023-03-30iov_iter: overlay struct iovec and ubuf/lenJens Axboe1-9/+35
Add an internal struct iovec that we can return as a pointer, with the fields of the iovec overlapping with the ITER_UBUF ubuf and length fields. Then we can have iter_iov() check for the appropriate type, and return &iter->__ubuf_iovec for ITER_UBUF and iter->__iov for ITER_IOVEC and things will magically work out for a single segment request regardless of either type.

2023-03-30iov_iter: add iter_iovec() helperJens Axboe1-3/+6
This returns a pointer to the current iovec entry in the iterator. Only useful with ITER_IOVEC right now, but it prepares us to treat ITER_UBUF and ITER_IOVEC identically for the first segment. Rename struct iov_iter->iov to iov_iter->__iov to find any potentially troublesome spots, and also to prevent anyone from adding new code that accesses iter->iov directly.
