1OpenChrome DDX Version 0.6 (March 7th, 2017) 2-------------------------------------------- 3 4OpenChrome DDX Version 0.6 is an improved version of OpenChrome DDX 5Version 0.5 with a number of improvements made to the code. OpenChrome 6DDX Version 0.6 is written in a way to completely replace Version 70.2.904 through 0.5. 8 9OpenChrome DDX Version 0.6 has added the following new features. 10 11- First official support for CX700, VX700, and VX800 chipsets 12 integrated TMDS transmitter (i.e., DVI support) 13- Initial support for Silicon Image SiI 164 TMDS transmitter 14 15 16OpenChrome DDX Version 0.6 has the following improvements. 17 18- Improved FP reinitialization when resuming from standby 19 (HP 2133 Mini-Note, FIC CE260 / CE261 based netbooks like 20 Everex CloudBook and Sylvania g netbook) 21- Improved automatic detection of display resources 22- Improved X Server stability in dual monitor mode 23- Automatic active steering of the display controller channel to the 24 correct display output device 25 26 27OpenChrome DDX Version 0.6 fixes the following bugs. 28 29- Fix for the disruption of the VT (Virtual Terminal) screen bug 30 introduced in Version 0.5 31- Fix for HP 2133 Mini-Note's PCIe WLAN getting turned off 32 inadvertently bug introduced in Version 0.5 33 34 35OpenChrome Version 0.5 (July 6th, 2016) 36--------------------------------------- 37 38Based on OpenChrome Version 0.4.0 code, OpenChrome Version 0.5 fixes 39several bugs while adding two new features. 40 41- Major code cleanup 42- Removal of more manual options (BusWidth, ForcePanel, and AccelMethod) 43- Fix for runtime screen resolution change X.Org Server crash bug 44- Fix for CLE266 chipset not being able to function correctly if 45 "CRT + TV" option was chosen in BIOS setup 46- Initial support for VIA Technologies VT1632A TMDS transmitter for DVI 47- Initial support for multiple display output (i.e., RandR) 48 49 50OpenChrome Version 0.4.0 (March 31st, 2016) 51------------------------------------------- 52 53OpenChrome Version 0.4.0 is a major break from the past versions where 54configuring the display resources were done manually. Now the displays 55are detected mostly automatically, although a few manual options still 56remain. These will be retired in the near future. Besides that, two 57alternative mode setting options were discontinued (VBE mode setting 58and "legacy" mode setting), in order to simplify the code. A regression 59affecting those with a DVI to VGA adapter, which appeared in OpenChrome 60Version 0.3.x, is now fixed. More importantly, devices that were not 61registered with a known device table (a large table that is located 62internally inside the code) used to crash during boot time, but since 63this table was removed completely, this bug does not appear anymore. 64 65- Removal of VBE (VESA BIOS Extension) mode setting 66 (removal of VBEModes and VbeSaveRestore options) 67- Removal of "legacy" mode setting 68 (removal of ModeSwitchMethod option) 69- Removal of ActiveDevice option 70- Removal of ForcePanel option 71- Removal of PanelSize option 72- Removal of a known device table internally 73- Mostly automatic display detection 74- Fix for a regression affecting those with DVI to VGA adapter 75- Fix for a boot time crash for devices that were not on the known 76 device table 77- Fix for a possible OLPC XO-1.5 detection issue (untested) 78- Fix for various small compilation warnings / errors 79 80 81openchrome 0.3.3 (23/05/2013) 82----------------------------- 83 84This is a bugfix release. 85- Fix integer overflow in libchromeXvMC (CVE-2013-1994). 86- Various bug fixes and improvements. 87 88 89openchrome 0.3.2 (27/03/2013) 90----------------------------- 91 92This is a bugfix release. 93- EXA fixes.

It mainly fixes a crash at startup with X server 1.13. 107 108 109openchrome 0.3.0 (20/07/2012) 110----------------------------- 111 112The 0.3.0 release is a major step forward for the openchrome X.org 113driver. It brings most of the features that are needed with todays X 114server. The code has seen a major overhaul, with a lot of new features 115and a lot of cleanup. It has been tested on most of the available VIA 116IGPs and we believe there are no regression at this point. However, the 117testing was done on a limited range of hardware, so your mileage may 118vary.

Hardware-accelerated cursor is on by 329 default, so this option was useless. Use the "SWCursor" option if you want to 330 disable HW cursor. 331- AGPDMA has been disabled for K8M800 and VM800/CN700/P4M800pro in this release 332 because it causes screen repaint and lockup issues. The problem has been 333 tracked down to a bug in kernel drm. All kernel >= 2.6.22 are affected. This 334 bug will be fixed in the upcoming 2.6.25-rc7. It is also fixed in current 335 drm git tree. If you're using one of the affected kernels, you'll have to 336 either keep AGPDMA disabled or build the modules from the fixed drm git 337 tree. This option brings extra performance for some operations. To use it, 338 add 'Option "EnableAGPDMA"' in the Device section of the xorg configuration. 339 340 341openchrome 0.2.901 (02/01/2008) 342------------------------------- 343* Enhancements : 344- New pci ids : FIC CE260, Hasee F700C, MSI P4M900M / P4M900M2-F/L, 345 PCChips V21G, Biostar P4M900M-M7 SE. 346- Identify the driver as Openchrome, with CHROME as a shorthand. 347- Report chipset too in case of an unknown card id. 348- Improve P4M890 memory detection. 349- Add VT1625 720x480Under, 720x480Fit and 720x480Over NTSC modes. 350- Add VT1625 720x576 PAL mode. 351 352* Fixes : 353- Panel on CX700 needs VBE. 354- K8M890 can use DDR667. 355- Never enable IRQ on KM400, KM400A owner will still need to enable manually. 356- Various code cleanups. 357 358openchrome 0.2.900 (20/10/2007) 359------------------------------- 360- First openchrome official release. 361
