Our driver supports overlay planes, and as expected, some userspace compositor takes advantage of these features. If the userspace is not enabling the cursor, they can use multiple planes as they please. Nevertheless, we start to have constraints when userspace tries to enable hardware cursor with various planes. Basically, we cannot draw the cursor at the same size and position on two separated pipes since it uses extra bandwidth and DML only run with one cursor. For those reasons, when we enable hardware cursor and multiple planes, our driver should accept variations like the ones described below: +-------------+ +--------------+ | +---------+ | | | | |Primary | | | Primary | | | | | | Overlay | | +---------+ | | | |Overlay | | | +-------------+ +--------------+ In this scenario, we can have the desktop UI in the overlay and some other framebuffer attached to the primary plane (e.g., video). However, userspace needs to obey some rules and avoid scenarios like the ones described below (when enabling hw cursor): +--------+ |Overlay | +-------------+ +-----+-------+ +-| |--+ | +--------+ | +--------+ | | +--------+ | | |Overlay | | |Overlay | | | | | | | | | | | | | | +--------+ | +--------+ | | | | Primary | | Primary | | Primary | +-------------+ +-------------+ +-------------+ +-------------+ +-------------+ | +--------+ | Primary | | |Overlay | | | | | | | | | +--------+ | +--------+ | | Primary | | |Overlay | | +-------------+ +-| |--+ +--------+ If the userspace violates some of the above scenarios, our driver needs to reject the commit; otherwise, we can have unexpected behavior. Since we don't have a proper driver validation for the above case, we can see some problems like a duplicate cursor in applications that use multiple planes. This commit fixes the cursor issue and others by adding adequate verification for multiple planes. Change since V1 (Harry and Sean): - Remove cursor verification from the equation.

So when vga_arbiter_notify_clients() iterates over registered clients, it causes NULL pointer dereference. Since there's no reason to register VGA clients that early, so solve the issue by putting them after all the goto cleanups. v2: - Remove redundant vga_switcheroo cleanup in failed: label.

After draining the stale retry fault, or failed to validate the range to recover, have to remove the fault address from fault filter ring, to be able to handle subsequent retry interrupt on same address. Otherwise the retry fault will not be processed to recover until timeout passed. Signed-off-by:

Add interface to remove address from fault filter ring by resetting fault ring entry key, then future vm fault on the address will be processed to recover. Define fault key as atomic64_t type to use atomic read/set/cmpxchg key to protect fault ring access by interrupt handler and interrupt deferred work for vg20. Change fault->timestamp to 48-bit to share same uint64_t with 8-bit fault->next, it is enough for 48bit IH timestamp. Signed-off-by:

Retry fault interrupt maybe pending in IH ring after GPU page table is updated to recover the vm fault, because each page of the range generate retry fault interrupt. There is race if application unmap range to remove and free the range first and then retry fault work restore_pages handle the retry fault interrupt, because range can not be found, this vm fault can not be recovered and report incorrect GPU vm fault to application. Before unmap to remove and free range, drain retry fault interrupt from IH ring1 to ensure no retry fault comes after the range is removed. Drain retry fault interrupt skip the range which is on deferred list to remove, or the range is child range, which is split by unmap, does not add to svms and have interval notifier. Signed-off-by:
