Revision 8f4fd86aa5d6aa122619623910065d236592e37c authored by David Woodhouse on 06 January 2021, 15:39:55 UTC, committed by Juergen Gross on 13 January 2021, 15:12:03 UTC
With INTX or GSI delivery, Xen uses the event channel structures of CPU0. If the interrupt gets handled by Linux on a different CPU, then no events are seen as pending. Rather than introducing locking to allow other CPUs to process CPU0's events, just ensure that the PCI interrupts happens only on CPU0.

Default video modes
-------------------
At the moment, there are two kernel command line arguments supported:
- mode:640x480
- mode:800x600
- mode:1024x768
Full support for startup video modes (modedb) will be integrated soon.
Version 1.9.9.1
---------------
* Fix memory detection for 512kB case
* 800x600 mode
* Fixed timings
* Hint for AXP: Use -accel false -vyres -1 when changing resolution
Version 1.9.4.4
---------------
* Preliminary Laguna support
* Overhaul color register routines.
* Associated with the above, console colors are now obtained from a LUT
called 'palette' instead of from the VGA registers. This code was
modelled after that in atyfb and matroxfb.
* Code cleanup, add comments.
* Overhaul SR07 handling.
* Bug fixes.
Version 1.9.4.3
---------------
* Correctly set default startup video mode.
* Do not override ram size setting. Define
CLGEN_USE_HARDCODED_RAM_SETTINGS if you _do_ want to override the RAM
setting.
* Compile fixes related to new 2.3.x IORESOURCE_IO[PORT] symbol changes.
* Use new 2.3.x resource allocation.
* Some code cleanup.
Version 1.9.4.2
---------------
* Casting fixes.
* Assertions no longer cause an oops on purpose.
* Bug fixes.
Version 1.9.4.1
---------------
* Add compatibility support. Now requires a 2.1.x, 2.2.x or 2.3.x kernel.
Version 1.9.4
-------------
* Several enhancements, smaller memory footprint, a few bugfixes.
* Requires kernel 2.3.14-pre1 or later.
Version 1.9.3
-------------
* Bundled with kernel 2.3.14-pre1 or later.
