OpenChrome DDX Version 0.6 (March 7th, 2017)
|
|
--------------------------------------------
|
|
|
|
OpenChrome DDX Version 0.6 is an improved version of OpenChrome DDX
|
|
Version 0.5 with a number of improvements made to the code. OpenChrome
|
|
DDX Version 0.6 is written in a way to completely replace Version
|
|
0.2.904 through 0.5.
|
|
|
|
OpenChrome DDX Version 0.6 has added the following new features.
|
|
|
|
- First official support for CX700, VX700, and VX800 chipsets
|
|
integrated TMDS transmitter (i.e., DVI support)
|
|
- Initial support for Silicon Image SiI 164 TMDS transmitter
|
|
|
|
|
|
OpenChrome DDX Version 0.6 has the following improvements.
|
|
|
|
- Improved FP reinitialization when resuming from standby
|
|
(HP 2133 Mini-Note, FIC CE260 / CE261 based netbooks like
|
|
Everex CloudBook and Sylvania g netbook)
|
|
- Improved automatic detection of display resources
|
|
- Improved X Server stability in dual monitor mode
|
|
- Automatic active steering of the display controller channel to the
|
|
correct display output device
|
|
|
|
|
|
OpenChrome DDX Version 0.6 fixes the following bugs.
|
|
|
|
- Fix for the disruption of the VT (Virtual Terminal) screen bug
|
|
introduced in Version 0.5
|
|
- Fix for HP 2133 Mini-Note's PCIe WLAN getting turned off
|
|
inadvertently bug introduced in Version 0.5
|
|
|
|
|
|
OpenChrome Version 0.5 (July 6th, 2016)
|
|
---------------------------------------
|
|
|
|
Based on OpenChrome Version 0.4.0 code, OpenChrome Version 0.5 fixes
|
|
several bugs while adding two new features.
|
|
|
|
- Major code cleanup
|
|
- Removal of more manual options (BusWidth, ForcePanel, and AccelMethod)
|
|
- Fix for runtime screen resolution change X.Org Server crash bug
|
|
- Fix for CLE266 chipset not being able to function correctly if
|
|
"CRT + TV" option was chosen in BIOS setup
|
|
- Initial support for VIA Technologies VT1632A TMDS transmitter for DVI
|
|
- Initial support for multiple display output (i.e., RandR)
|
|
|
|
|
|
OpenChrome Version 0.4.0 (March 31st, 2016)
|
|
-------------------------------------------
|
|
|
|
OpenChrome Version 0.4.0 is a major break from the past versions where
|
|
configuring the display resources were done manually. Now the displays
|
|
are detected mostly automatically, although a few manual options still
|
|
remain. These will be retired in the near future. Besides that, two
|
|
alternative mode setting options were discontinued (VBE mode setting
|
|
and "legacy" mode setting), in order to simplify the code. A regression
|
|
affecting those with a DVI to VGA adapter, which appeared in OpenChrome
|
|
Version 0.3.x, is now fixed. More importantly, devices that were not
|
|
registered with a known device table (a large table that is located
|
|
internally inside the code) used to crash during boot time, but since
|
|
this table was removed completely, this bug does not appear anymore.
|
|
|
|
- Removal of VBE (VESA BIOS Extension) mode setting
|
|
(removal of VBEModes and VbeSaveRestore options)
|
|
- Removal of "legacy" mode setting
|
|
(removal of ModeSwitchMethod option)
|
|
- Removal of ActiveDevice option
|
|
- Removal of ForcePanel option
|
|
- Removal of PanelSize option
|
|
- Removal of a known device table internally
|
|
- Mostly automatic display detection
|
|
- Fix for a regression affecting those with DVI to VGA adapter
|
|
- Fix for a boot time crash for devices that were not on the known
|
|
device table
|
|
- Fix for a possible OLPC XO-1.5 detection issue (untested)
|
|
- Fix for various small compilation warnings / errors
|
|
|
|
|
|

|
|
|
|
openchrome 0.3.0 (20/07/2012)
|
|
-----------------------------
|
|
|
|
The 0.3.0 release is a major step forward for the openchrome X.org
|
|
driver. It brings most of the features that are needed with todays X
|
|
server. The code has seen a major overhaul, with a lot of new features
|
|
and a lot of cleanup. It has been tested on most of the available VIA
|
|
IGPs and we believe there are no regression at this point. However, the
|
|
testing was done on a limited range of hardware, so your mileage may
|
|
vary. Please let us know if you have any trouble using it.
|
|
|
|
* New Features :
|
|
- TTM/GEM support.
|
|
- KMS support.
|
|
- Better RandR support.
|
|
- XAA removal.
|
|
- DGA removal.
|
|
- Support for X server 1.13 API.

|
- Code cleanup and bug fixes.
|
|
|
|
* Known bugs and limitations :
|
|
- Dual screen is not fully working.
|
|
- EXA compositing is disabled.
|
|
- KMS-enabled DRM module is not in upstream kernel yet.
|
|
|
|

|
|
freedesktop.org bug tracker.

openchrome 0.2.902 (08/04/2008)
|
|
-------------------------------
|
|
* Enhancements and bug fixes:
|
|
- libpciaccess support.
|
|
- Fix Xv on LCD for VM800/CN700/P4M800pro.
|
|
- Fix P4M900 fifo setting.

|
|
(aka Everex Cloudbook CE1200V), VIA Epia SN.
|
|
|
|
* Notes:
|
|
- The "HWCursor" option has been removed. Hardware-accelerated cursor is on by
|
|
default, so this option was useless. Use the "SWCursor" option if you want to
|
|
disable HW cursor.
|
|
- AGPDMA has been disabled for K8M800 and VM800/CN700/P4M800pro in this release
|
|
because it causes screen repaint and lockup issues. The problem has been
|
|
tracked down to a bug in kernel drm. All kernel >= 2.6.22 are affected. This
|
|
bug will be fixed in the upcoming 2.6.25-rc7. It is also fixed in current
|
|
drm git tree. If you're using one of the affected kernels, you'll have to
|
|
either keep AGPDMA disabled or build the modules from the fixed drm git
|
|
tree. This option brings extra performance for some operations. To use it,
|
|
add 'Option "EnableAGPDMA"' in the Device section of the xorg configuration.
|
|
|

|
|
|

|
|

|
|
- Never enable IRQ on KM400, KM400A owner will still need to enable manually.
