the failure

HW has limited bits for wave scratch base address stride. Enforcement
prevents programs with larger than supported scratch allocations from
running and clobbering neighboring scratch space.

BaseQueue class has a member function GetQueueType so m_Type
is duplicated. m_Type is only used in one function. Move it to
a local variable.

EPERM means "operation not permitted" and is returned when CGroup
access checks fail. EACCES means "permission denied" and is returned
when the device file permission bits or access control list don't
allow access.
EPERM can fail silently, since we assume the administrator disabled
a device on purpose in the CGroup. EACCESS should produce an error
message and an info message to check the device file permissions.

Also rename blit_agent to region_gpu and add comments to clarify
its role in deprecated region API support rather than to do blits.

During registration we must not call any function that depends on registered
data as the lists are not yet complete. This includes signal allocation since
allocating shared GPU mapped memory depends on the list of GPUs.
