DPMS support for DFP on R128
Meanwhile I have tried te patch against xorg-x11-drv-ati-6.5.7.3-4 and it
works.
I add the current patch as file here.
I've applied this upstream and to our ati driver, thanks! |
Description of problem: No DPMS on DFP monitor with ATI R128. Version-Release number of selected component (if applicable): currently xorg-x11-drv-ati-6.5.7.3-4 How reproducible: Always. Steps to Reproduce: 1. xset dpms force off 2. 3. Actual results: screen blanks, background light remains on; monitor sometimes gives signal error Expected results: monitor goes off Additional info: Before I used fedora I had my Xfree compiled by myself. To get DPMS working I need to add the following patch to the driver: ---------------------------------- --- xc/programs/Xserver/hw/xfree86/drivers/ati/r128_driver.c.orig 2003-07-29 23:45:08.000000000 +0200 +++ xc/programs/Xserver/hw/xfree86/drivers/ati/r128_driver.c 2003-07-29 23:50:00.000000000 +0200 @@ -3651,6 +3651,18 @@ OUTREGP(R128_CRTC_EXT_CNTL, mask, ~mask); break; } + if(info->isDFP) { + switch (PowerManagementMode) { + case DPMSModeOn: + OUTREG(R128_FP_GEN_CNTL, INREG(R128_FP_GEN_CNTL) | (R128_FP_FPON | R128_FP_TDMS_EN)); + break; + case DPMSModeStandby: + case DPMSModeSuspend: + case DPMSModeOff: + OUTREG(R128_FP_GEN_CNTL, INREG(R128_FP_GEN_CNTL) & ~(R128_FP_FPON | R128_FP_TDMS_EN)); + break; + } + } } static int r128_set_backlight_enable(ScrnInfoPtr pScrn, int on); ------------------------------ I haven't tried this patch on the current driver version but I guess it will more or less apply. It would be nice if we could have a r128 driver that supports DPMS on DFP monitors. Thanks! Ronald
