Fix our pointer offset usage in error_state_read when there is no i915_gpu_coredump but buf offset is non-zero. This fixes a kernel page fault can happen when multiple tests are running concurrently in a loop and one is producing engine resets and consuming the i915 error_state dump while the other is forcing full GT resets. (takes a while to trigger).

PVC also has a hwconfig table. Actually the current expectation is that all future platforms will have hwconfig, so let's just change the condition to an IP version check so that we don't need to keep updating this for each new platform that shows up.

Let's reorganize some of the forcewake/shadow handling in intel_uncore.c and consolidate the cargo-cult comments on each table into more general comments that apply to all tables. We'll probably move forcewake handling to its own dedicated file in the near future and further enhance this with true kerneldoc.

Currently we have some corner cases where area calculation fails. For these sel fetch area calculation ends up having update area as y1 = 0, y2 = 4. Instead of these values safer option is full update. One of such for example is big fb with offset. We don't have usable offset in psr2_sel_fetch_update.

Nathan Chancellor authored
When an attribute group is created with sysfs_create_group(), the ->sysfs_ops() callback is set to kobj_sysfs_ops, which sets the ->show() callback to kobj_attr_show(). kobj_attr_show() uses container_of() to get the ->show() callback from the attribute it was passed, meaning the ->show() callback needs to be the same type as the ->show() callback in 'struct kobj_attribute'. However, show_dynamic_id() has the type of the ->show() callback in 'struct device_attribute', which causes a CFI violation when opening the 'id' sysfs node under drm/card0/metrics. This happens to work because the layout of 'struct kobj_attribute' and 'struct device_attribute' are the same, so the container_of() cast happens to allow the ->show() callback to still work. Change the type of show_dynamic_id() to match the ->show() callback in 'struct kobj_attributes' and update the type of sysfs_metric_id to match, which resolves the CFI violation.

There are 2 ways an engine can get reset in i915 and the method of reset affects how KMD labels a context as guilty/innocent. (1) GuC initiated engine-reset: GuC resets a hung engine and notifies KMD. The context that hung on the engine is marked guilty and all other contexts are innocent. The innocent contexts are resubmitted. (2) GT based reset: When an engine heartbeat fails to tick, KMD initiates a gt/chip reset. All active contexts are marked as guilty and discarded. In order to correctly mark the contexts as guilty/innocent, pass a mask of engines that were reset to __guc_reset_context.
