[virglrenderer-devel] [PATCH 0/4] Provide the means to inject info about the host GL into a qemu guest

[Gert Wollny]

Dear all, 

this is a reworked proposal to make it possible to obtain information about 
the host GL and virglrender version from within the guest. The series doesn't
require any changes to the guest version of virgl or to qemu. Instead it
provides the means to inject this information into the guest system by using
smbios OEM strings. 

The first two patches are simple fixes to the existing code, the third patch 
adds the means to inject the git sha for the current version into the build
(mostly taken from mesa), and adds and exposes a function to read this and the
OpenGL version information of the currenly active context. This function could
also be called from Qemu, and if you think that this is a good idea, then I
will propose a patch (It would make sure that the information inside the guest
really corresponds to the GL context Qemu is using.) 
The last patch finally adds a command line program that prints out the version
information that can be injected into the guest via the -smbios command line 
parameter provided by qemu (see corresponding commit message).

Best, 
Gert
