Subject: [PATCH xserver] mustard: xfree86: Only call the driver's
|
|
|
976099 |
platformProbe
|
|
|
976099 |
|
|
|
976099 |
The code to detangle what's a PCI device and what's platform is... bad.
|
|
|
976099 |
The PCI-specific initialization path should never be necessary these
|
|
|
976099 |
days, and the ancient "just probe something" path should especially
|
|
|
976099 |
never be necessary, so we can avoid a bunch of fragile code by simply
|
|
|
976099 |
never calling into the non-platform probe paths and letting platform
|
|
|
976099 |
handle everything.
|
|
|
976099 |
|
|
|
976099 |
Among other things this fixes hypervdrm on v1 devices, which have both a
|
|
|
976099 |
PCI and a platform presentation, in a way that would cause X to fail to
|
|
|
976099 |
start.
