NAME
gvid_no_claim_dev — PCI Vendor/Device ID that the gvid graphics driver will not claim
VALUES
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
graphics 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 parameter 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
