We are able to repro 100% in the Android container under Chrome OS running Linux kernel 4.4 and Mesa 18. We can also repro under Celadon/NUC/drm tip running kernel 4.19 and Mesa 18. The code from the upper layer is here : <a href="http://androidxref.com/9.0.0_r3/xref/external/skia/gm/mixedtextblobs.cpp#20">http://androidxref.com/9.0.0_r3/xref/external/skia/gm/mixedtextblobs.cpp#20</a> There are 3 main draw calls() 26 SkPaint paint(skPaint); 28 canvas->drawRect(clipRect, clipHairline); 30 canvas->drawTextBlob(blob, 0, 0, paint); 33 canvas->drawTextBlob(blob, 0, 0, paint); We are still trying to see what these functions are in GL apis (more soon). The IPHER, which points to the command that hung is at IPEHR: 0x78260000, and that address point to 3DSTATE_BINDING_TABLE_POINTERS_VS 0xe60003ac: 0x784f0000: 3D UNKNOWN: 3d_965 opcode = 0x784f 0xe60003b0: 0x90000100: UNKNOWN 0xe60003b4: 0x78230000: 3D UNKNOWN: 3d_965 opcode = 0x7823 0xe60003b8: 0x00000140: MI_NOOP 0xe60003bc: 0x78260000: 3DSTATE_BINDING_TABLE_POINTERS_VS 0xe60003c0: 0x00000000: dword 1 0xe60003c4: 0x78270000: 3DSTATE_BINDING_TABLE_POINTERS_HS 0xe60003c8: 0x00000000: dword 1 0xe60003cc: 0x78280000: 3DSTATE_BINDING_TABLE_POINTERS_DS 0xe60003d0: 0x00000000: dword 1 0xe60003d4: 0x78290000: 3DSTATE_BINDING_TABLE_POINTERS_GS 0xe60003d8: 0x00000000: dword 1 0xe60003dc: 0x782a0000: 3DSTATE_BINDING_TABLE_POINTERS_PS 0xe60003e0: 0x00000160: dword 1 The documentation says this: The 3DSTATE_BINDING_TABLE_POINTERS_VS command is used to define the location of fixed functions' BINDING_TABLE_STATE. Only some of the fixed functions utilize binding tables.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
