Hi. I am trying to make a ddx exa video driver at my owned target. When I test the driver, I have met some error from Xserver. The error log is bleow, ========================================= Fatal server error: exaGetPixmapFirstPixel called for invalid bpp 1 =========================================
And backtrace at the exaGetPixmapFirstPixel function is below ========================================================== Breakpoint 1, exaGetPixmapFirstPixel (pPixmap=0x477618) at ../../exa/exa_unaccel.c:507 507 switch (pPixmap->drawable.bitsPerPixel) { (gdb) bt #0 exaGetPixmapFirstPixel (pPixmap=0x477618) at ../../exa/exa_unaccel.c:507 #1 0x406529c0 in exaTryDriverSolidFill (pSrc=0x488ec0, pDst=0x488ce0, xSrc=0, ySrc=0, xDst=5, yDst=10, width=1, height=127) at ../../exa/exa_render.c:300 #2 0x40654c88 in exaComposite (op=1 '\001', pSrc=0x488ec0, pMask=0x0, pDst=0x488ce0, xSrc=0, ySrc=0, xMask=0, yMask=0, xDst=5, yDst=10, width=1, height=127) at ../../exa/exa_render.c:923 #3 0x0014ccc4 in damageComposite (op=1 '\001', pSrc=0x488ec0, pMask=0x0, pDst=0x488ce0, xSrc=0, ySrc=0, xMask=0, yMask=0, xDst=5, yDst=10, width=1, height=127) at ../../../miext/damage/damage.c:643 #4 0x0013392c in CompositePicture (op=1 '\001', pSrc=0x488ec0, pMask=0x0, pDst=0x488ce0, xSrc=0, ySrc=0, xMask=0, yMask=0, xDst=5, yDst=10, width=1, height=127) at ../../render/picture.c:1718 #5 0x0013b24c in ProcRenderComposite (client=0x433898) at ../../render/render.c:723 #6 0x00140324 in ProcRenderDispatch (client=0x433898) at ../../render/render.c:2056 #7 0x00024650 in Dispatch () at ../../dix/dispatch.c:445 #8 0x00022414 in main (argc=11, argv=0xbec9bd04, envp=0xbec9bd34) at ../../dix/main.c:285 (gdb) p pPixmap->drawable.bitsPerPixel $1 = 1 '\001' ============================================================= At exaGetPixmapFirstPixel, the xserver calls the FatalError when the bpp of the pixmap is 1. I have two questions at this point. 1. Is this exa module bug? I mean the xserver has the bug? 2. Or my ddx video driver does not being working properly? Especially, should I fix the createpixmap in my ddx driver? - Should the my ddx driver deal with 1bpp pixmap as the special case when the driver create the pixmap or modify the pixmap header? I mean that the createpixmap in the ddx driver makes the bitsPerPixel 8bits when the pixmap with 1bpp is requested . Is there anyone who has the solution in this case? Thanks. soolim.
