| | * | | | xen: events: refactor GSI pirq bindings functionsIan Campbell2011-03-101-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Following the example set by xen_allocate_pirq_msi and xen_bind_pirq_msi_to_irq: xen_allocate_pirq becomes xen_allocate_pirq_gsi and now only allocates a pirq number and does not bind it. xen_map_pirq_gsi becomes xen_bind_pirq_gsi_to_irq and binds an existing pirq.

However in the 2.6.39 version of pciback xen_pirq_from_irq is, correctly AFAICT, used instead. Only a minority of functions in events.h use "extern" so drop it from those places for consistency.

Instead of leaking memory, use pages that have already been ballooned out and so have no valid mapping. This removes the need for the bad-page leak workaround as pages are repopulated by the balloon driver.

This is especially bad in the case of GNTMAP_contains_pte mapping type mappings where m2p_add_override will destroy the kernel mapping of the page. This was observed via a failure of map_grant_pages in gntdev_mmap (due to userspace using a bad grant reference), which left the page in question unmapped (because it was a GNTMAP_contains_pte mapping) which led to a crash later on.

Note: The HVM path for map and unmap is slightly different: HVM keeps the pages mapped until the area is deleted, while the PV case (use_ptemod being true) must unmap them when userspace unmaps the range. In the normal use case, this makes no difference to users since unmap time is deletion time.

Change to a global limit and remove the ioctl() as the parameter can now be changed via sysfs. Xen tools changeset 22768:f8d801e5573e is needed to eliminate the error this change produces in xc_gnttab_set_max_grants.

The guest is expected to acknowledge that it will complete a request by clearing the control node. Previously it would acknowledge any request, even if it did not know what to do with it. Specifically in the case where CONFIG_PM_SLEEP is not enabled the kernel would acknowledge a suspend request even though it was not actually going to do anything. Instead make the kernel only acknowledge requests if it is actually going to do something with it. This will improve the toolstack's ability to diagnose and deal with failures.
