|
|
** Look for "EDIT THIS LIST" to add to the list of known devices
|
|
**
|
|
**
|
|
** There are a number of assumptions made in this code.
|
|
**
|
|
** - That the console supports a minimal set of ANSI escape sequences
|
|
** (See the screen manipulation section for a summary)
|
|
** and has at least 24 rows.
|
|
** - That values less than or equal to zero for any of the device
|
|
** parameters indicate that the driver does not use the parameter.
|
|
** - That the only tunable parameter for PCI devices are their flags.
|
|
** - That flags are _always_ editable.
|
|
**
|
|
** Devices marked as disabled are imported as such. It is possible to move
|
|
** a PCI device onto the inactive list, but it is not possible to actually
|
|
** prevent the device from being probed. The ability to move is considered
|
|
** desirable in that people will complain otherwise 8)
|
|
**
|
|
** For this tool to be useful, the list of devices below _MUST_ be updated
|
|
** when a new driver is brought into the kernel. It is not possible to
|
|
** extract this information from the drivers in the kernel, as the devconf
|
|
** structure for the device is not registered until the device is probed,
|
|
** which is too late.
|
|
**
|
|
** XXX - TODO:
|
|
**
|
|
** - FIX OPERATION WITH PCVT!
|
|
**
|
|
** - Display _what_ a device conflicts with.
|
|
** - Implement page up/down (as what?)
|
|
** - Wizard mode (no restrictions)
|
|
** - Find out how to put syscons back into low-intensity mode so that the
|
|
** !b escape is useful on the console.
|
|
** - The min and max values used for editing parameters are probably
|
|
** very bogus - fix?
|
|
**
|
|
** - Only display headings with devices under them. (difficult)
