Most occurances of U32 were converted to u32. These are cases where
the data represents something that will be written to the hardware.
Other cases were converted to 'unsigned int'.
U32 was the last type in xgi_types.h, so that file is removed.
These two structures were used as the request and reply for certain
ioctls. Having a different type for an ioctl's input and output is
just wierd. In addition, each structure contained fields (e.g., pid)
that had no business being there.
This change requires updates to user-space.
Allows multiple references to a single object, needed to support PCI(E)GART
scatter-gather DMA objects which would quickly fill PRAMIN if each channel
had its own.
Handle per-channel private instmem areas. This is needed to support NV50,
but might be something we want to do on earlier chipsets at some point?
Everything that touches PRAMIN is a GPU object.
Two large blocks of code were moved out of this function into separate
functions. This brought some much needed sanity to the indentation.
Some dead varaibles were removed.
Dave Airlie pointed out on IRC that idr_replace lets us know if the ID hasn't
been allocated, so we don't need a special pointer value for allocated IDs that
don't have valid information yet.
There's a difference between a drawable ID not having valid drawable
information and not being allocated at all. Not making the distinction would
break i915 DRM swap scheduling with older X servers that don't push drawable
cliprect information to the DRM.
The whole purpose of xgi_pcie_heap_check is to log information about
entries on the used_list. If XGI_DEBUG is not set, it doesn't print
anything. Therefore we can #ifdef the whole function body.
Convert open-code list iteration to use list_for_each_entry.
Comment in the code explains it. Basically, I put an if-statement
around a block of code to prevent a NULL pointer dereference that
should never happen in the first place. Eventually, this will need to
come out.
This function used to return 'void *', which was then cast to
'xgi_pcie_block_t *' at the only caller. I changed the return type to
'struct xgi_pcie_block_s *' and removed the explicit cast.
