kernel graphics drivers

All OEM graphics devices on HP-UX IPF systems use multiple kernel graphics drivers. These
kernel drivers include GVID (General VIDeo driver) and separate graphics DLKM (Dynamic
Loadable Kernel Modules). All DLKMs are loaded when needed, instead of being statically
linked into the kernel. This means that a new kernel does not need to be built every time a new
graphics module is needed. GVID is not a DLKM, but it is statically built into the kernel. GVID
is device-independent.
The usage of DLKMs is very different for the 11.22 version of HP-UX and subsequent versions
of HP-UX. Both versions of DLKMs are discussed in this section.
Like any other part of the system, there is the potential that the DLKMs become corrupted. There
are simple commands that allow you to determine if the DLKMs are functioning properly.

correctly configured 11.22 system

To determine if the DLKMs are loaded correctly on HP-UX 11.22 systems, run the command
/usr/sbin/kmadmin -s (as root). This displays the currently loaded/used DLKMs. The
DLKMs that you should see for a correctly configured graphics system are gvid_info, the DRM,
and the HIM (Hardware Init Module). For example, for an ATI FireGL X1 device, you should
verify that the following three modules are present (there may be other modules listed, but these
three are needed):
Name
gvid_info
drmfglrx
gvid_him_rad
The status of the drmfglrx and gvid_him_rad modules may be LOADED if you are currently
using the graphics device (for example, the X Server is running). If you do not see the above
modules listed, you may have to reload the modules.
