permissions when no access to HW registers is required. For API changes
which mostly involve the modifications to make the RRFunc (introduced
with 6.8) more flexible please check Bugzilla #2407. NOTE: This patch
applies changes to OS specific files for other OSes which I cannot
test.
but includes debugging to ensure that the reg being submitted is the
one that follows in the packet. Convert most uses of OUT_RING to it,
and convert a couple of OUT_REG sets to DMA_PACKET0/OUT_RING_REG. Also,
add checking to see if more registers are submitted to a DMA_PACKET0
than should be, to avoid hangs during stupid mistakes (checking for
less isn't done).
virtually impossible to determine if the old code did what it was
supposed to do. Also changed paradigm: Trust the based address more
than the (guessed) size. (Bugzilla #2383)
reading a register/attempting DMA. Now it'll wait for a certain number
of seconds rather than a certain number of times through the loop
before deciding that it's timed out and resetting the hardware. Also,
add more timeout handling, and reset the draw state after resetting the
engine.
problems on may systems which don't support APM standby and might not
be required as according to the APM specs the chips should receive
enough power to retain its state.
- Print out power state change requests to log file in all verbosity
levels.
- Don't change server state if no driver PM function is registered.

relied on the generic VGA layer to restore text console fonts for us
when shutting down the server or VT switching back to the text console.
This has worked rather well but it has some downsides on Linux: a. Many
people use fbdev as console text mode. In this case it is not necessary
to save/restore console fonts as the console is running in graphics
mode anyway. b. Some architectures don't have a fbdev console but
require a full POST of even the primary card (ie. IA64). This posting
has to take place before we even have a chance to save anything.
Therefore the fonts we save are the once written to the chip by POST,
not what has been programmed by the user. c. Certain chipsets utilize
the BIOS to perform mode setting. This may interfer with the vga
save/restore font function in a strange way. It would therefore be
preferrable to let the OS - which has been used to set up the font in
the first place - take care of saving/restoring the data. I will attach
a patch which will do so for Linux. To make this fully functional a
small patch needs to be applied to the Linux kernel. To disable this
feature add: #define DoOSFontRestore NO to your host.def. (Bugzilla
#2277)
Make sure the pixmap is a valid new resource
Make sure the context is a legal new resource.

"translucent window".
