2018-05-23drm/vmwgfx: Fix 32-bit VMW_PORT_HB_[IN|OUT] macrosThomas Hellstrom1-8/+17
Depending on whether the kernel is compiled with frame-pointer or not, the temporary memory location used for the bp parameter in these macros is referenced relative to the stack pointer or the frame pointer. Hence we can never reference that parameter when we've modified either the stack pointer or the frame pointer, because then the compiler would generate an incorrect stack reference. Fix this by pushing the temporary memory parameter on a known location on the stack before modifying the stack- and frame pointers.

2016-05-20drm/vmwgfx: Add VMWare host messaging capabilitySinclair Yeh1-0/+191
This patch adds capabilities for a VMWare guest to send and receive messages from the host, and adds functions to sending log messages to vmware.log and to request device settings that aren't available through the virtual hardware, e.g. certain settings in the VMX file.
