(Tunable Kernel Parameters)
NAME
gvid_no_claim_dev - PCI Vendor/Device ID that the gvid graphics driver will not claim
VALUES
Failsafe
0
Default
0
Allowed values
0 to 0xFFFFFFFF (4294967295)
Recommended values
Specific to the device you wish to prevent
gvid from claiming.
DESCRIPTION
This tunable specifies the PCI Vendor ID and/or Device ID of a graphics device that the HP
gvid graph-
ics driver should not claim.
The
gvid graphics driver was designed to be a general purpose driver for all PCI graphics cards. As a
result, the gvid driver will attempt to claim any PCI graphics display device found on the system. This
can be a problem for graphics device developers who need their own graphics driver to claim their own
graphics device.
The value of
gvid_no_claim_dev
will specify a PCI Vendor ID and/or Device ID of a graphics card
that the gvid graphics driver should not claim. It is a 32 bit number, with the upper 16 bits containing
the PCI Vendor ID and the lower 16 bits containing the PCI Device ID. Either the Vendor ID or Device
ID can use a wildcard value of
0xFFFF.
For example, if
gvid_no_claim_dev
is set to the value 0x1234ABCD, the gvid driver will ignore
graphics devices with a PCI Vendor ID of
0x1234 and a Device ID of
0xABCD.If
gvid_no_claim_dev
is set to 0x4567FFFF, the gvid driver will not claim any graphics cards with a
Vendor ID of
0x4567, regardless of the Device ID.
Who Is Expected to Change This Tunable?
Anyone who wishes the
gvid graphics driver to ignore a specific graphics device. This will typically be
someone writing their own graphics driver for their own hardware.
Restrictions on Changing
Changes to this tunable take effect at the next reboot.
What Other Tunables Should Be Changed at the Same Time?
None.
WARNINGS
All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its
meaning changed in future releases of HP-UX.
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parame-
ter values. After installation, some tunable parameters may no longer be at the default or recommended
values. For information about the effects of installation on tunable values, consult the documentation for
the kernel software being installed. For information about optional kernel software that was factory
installed on your system, see HP-UX Release Notes at
