Hello, We ran into a performance problem with pixman 0.19.6 on a PXA270 ARM Linux system, where we were getting unaligned exceptions. The backtrace is:
#0 bits_image_fetch_bilinear_affine (image=0x177280, offset=<value optimized out>, line=<value optimized out>, width=500, buffer=0xbeba03a0, mask=0x0) at pixman-bits-image.c:885 ‣ #1 bits_image_fetch_bilinear_affine_none_r5g6b5 (image=0x177280, offset=<value optimized out>, line=<value optimized out>, width=500, buffer=0xbeba03a0, mask=0x0) at pixman-bits-image.c:963 ‣ #2 0x40138440 in _pixman_image_get_scanline_32 (image=0xe4, x=228, y=-256, width=-65536, buffer=0xbeba03a0, mask=0x0) at pixman-image.c:145 ‣ #3 0x40168908 in general_composite_rect (imp=0x20505042, op=3657433216, src=Cannot access memory at address 0x88) at pixman-general.c:219 ‣ #4 0x4016a458 in pixman_image_composite32 (op=PIXMAN_OP_SRC, src=0x177280, mask=0x0, dest=0x177370, src_x=11, src_y=200, mask_x=0, mask_y=0, dest_x=20, dest_y=400, width=500, height=33) at pixman.c:839 ‣ #5 0x0005f4a8 in fbComposite () ‣ #6 0x000cc048 in damageComposite () ‣ #7 0x000b6420 in CompositePicture () ‣ #8 0x000bc1a0 in ProcRenderComposite () ‣ #9 0x000b9250 in ProcRenderDispatch () ‣ #10 0x00097db8 in XaceCatchExtProc () ‣ #11 0x0002d5e0 in Dispatch () ‣ #12 0x00014604 in main () With pixman 0.20.0, we don't see the problem. Just wanted to report in case there might still be something lurking.
