The problem is:
- Currently thoses fields are not initialised. Since the structure is declared
"static", they are initialised at 0.
So the driver claim to be compatible with DRM version 0.0.0 and the pointers
are NULL. This lead to the following log in dmesg:
Oct 5 19:18:48 portable kernel: [drm] Initialized drm 1.0.1 20051102
Oct 5 19:18:48 portable kernel: ACPI: PCI Interrupt 0000:01:00.0[A] -> Link
[LNKC] -> GSI 5 (level, low) -> IRQ 5
Oct 5 19:18:48 portable kernel: [drm] Initialized <NULL> 0.0.0 <NULL> on minor 0
Oct 5 19:18:48 portable kernel: [drm:mach64_dma_init] *ERROR* mach64_dma_init
called without lock held
Oct 5 19:18:48 portable kernel: [drm:drm_unlock] *ERROR* Process 2971 using
kernel context 0
And X complain that the DRM version is incompatible then DRI fail to initialize.
With the patch, the driver claim to support the correct version, and everything
is fine:
Oct 8 20:50:48 portable kernel: [drm] Initialized drm 1.0.1 20051102
Oct 8 20:50:48 portable kernel: ACPI: PCI Interrupt 0000:01:00.0[A] -> Link
