kernel/drivers/gpu/drm/vmwgfx/vmwgfx_msg.h, branch linux-4.17.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-4.17.y2018-05-23T14:11:24Zdrm/vmwgfx: Fix 32-bit VMW_PORT_HB_[IN|OUT] macros2018-05-23T14:11:24ZThomas Hellstromthellstrom@vmware.com2018-05-23T14:11:24Zurn:sha1:938ae7259c908ad031da35d551da297640bb640c
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.

drm/vmwgfx: Add VMWare host messaging capability2016-05-20T15:12:33ZSinclair Yehsyeh@vmware.com2016-04-28T02:10:19Zurn:sha1:89da76fde68de1205756707133508e930be4f389
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.
