Re: [Beignet] Unrecoverable system lockup when allocating too much memory

Would this be better if you turn off the overcommit via proc fs? Only if you also disable any swap space ( sudo swapoff -a && sudo sh -c "echo -n 2 > /proc/sys/vm/overcommit_memory" #warning, this may itself crash your desktop); if I disable overcommit but leave swap on, I get a hang with

[Beignet] [PATCH v6 2/4] Add extensions intel_accelerator and basic intel_motion_estimation.

v2: 1. Just upload the first vme_state. 2. Remove duplicated code in check_opt1_extension. 3. Check image format before cl_gpgpu_bind_image_for_vme. 4. Fix error of getting mv. Because we suppose this kernel run in SIMD16 mode, so dword 0 of grf 1 should be __gen_ocl_region(8,vme_result.s0),

[Beignet] [PATCH v6 1/4] Add built-in function __gen_ocl_vme.

__gen_ocl_vme is used for hardware accelerated video motion estimation. It gets payload values as parameters and uses MOV to pass these payload values to VME SEND Message's payload grfs. The int8 return value is used to store SEND Message writeback. v2: Remove unnecessary 5 parameters(src_grf*)

Re: [Beignet] [PATCH] GBE: fix printf class static variable bug

Thread_local is not needed to pass data from one llvm pass to another. You can still access the info after pass that has already run. In a later llvm pass, you can use getAnalysis() to get the the PrintfParser pass handle. Then expose an interface in PrintfParser like map

Re: [Beignet] [PATCH] GBE: fix printf class static variable bug

Yes, but the problem is that if two thread has kernel with printf functions, the map printfs will be cleared in construction and destructor. This will cause the one who is still need info in printfs get null pointer. thread_local now is to protect printfs from other thread but not pass data from
