Hi,
I'm running xorg-server 1.8.2 on my device and I have run into
problems with Damage Extension registration in the new Xorg-server
code.
A little bit of history:
I have a system having Intel Integrated graphics with psb driver
(psb_drv.so) and i had modified the driver code to register with
damage extension with no problems in Xserver 1.6.5.
I used in the psb driver load function:
DrawablePtr RootWinDraw = &WindowTable[DisplayNum]->drawable;
// Report
Func , Clean Func RawRectangles, isInternal=TRUE ,
ScreenPtr, CustomStructure
DamagePtr dmg= DamageCreate(dmgReportFunc, dmgCleanFunc,
DamageReportLevel, TRUE, pScr, pScrn);
if (dmg)
//DrawablePtr , DamagePtr
DamageRegister(RootWinDraw,dmg);
This section of code worked correctly in Xserver 1.6.5 and I was able
to obtain damage reports whenever there was a change in screen.
But in the xorg-server 1.8.2, My XServer crashes and I root caused it
to the RootWinDraw pointer. The problem seems to be that the
WindowTable[0]->drawable is not giving me root window anymore.
Is there any way in which i can get the root window drawable from
within the driver? And also what has changed in the WindowTable
mechanism from 1.6.5 to 1.8.2? I didnt find anything different in
their initialization mechanisms.
Any pointers will be very helpful.
Thanks.
