Modularize code: main.c -> device-cpu + device-gpu This patch is an initial attempt to re-structure cgminer source code from its monolithic design (with nearly all code being concentrated in main.c) to a more modular one. In this first stage, the conditionally compiled functions for GPU and CPU mining were extracted into dedicated files: * device-cpu.h and device-cpu.c covering WANT_CPUMINE functions * device-gpu.h and device-gpu.c covering HAVE_OPENCL functions The main.c file is left untouched as reference, while the remainder without the extracted parts is located in cgminer.c. The Makefile.am has been updated to use the re-structured source files for the build. Above pure re-structuring *NO* functional modifications were made. The sources were tested to compile and run on on a current Linux system with working CPU and GPU mining (Bitforce not tested due to loack of hardware).

Modularize code: main.c -> device-cpu + device-gpu This patch is an initial attempt to re-structure cgminer source code from its monolithic design (with nearly all code being concentrated in main.c) to a more modular one. In this first stage, the conditionally compiled functions for GPU and CPU mining were extracted into dedicated files: * device-cpu.h and device-cpu.c covering WANT_CPUMINE functions * device-gpu.h and device-gpu.c covering HAVE_OPENCL functions The main.c file is left untouched as reference, while the remainder without the extracted parts is located in cgminer.c.

Modularize code: main.c -> device-cpu + device-gpu This patch is an initial attempt to re-structure cgminer source code from its monolithic design (with nearly all code being concentrated in main.c) to a more modular one. In this first stage, the conditionally compiled functions for GPU and CPU mining were extracted into dedicated files: * device-cpu.h and device-cpu.c covering WANT_CPUMINE functions * device-gpu.h and device-gpu.c covering HAVE_OPENCL functions The main.c file is left untouched as reference, while the remainder without the extracted parts is located in cgminer.c. The Makefile.am has been updated to use the re-structured source files for the build. Above pure re-structuring *NO* functional modifications were made. The sources were tested to compile and run on on a current Linux system with working CPU and GPU mining (Bitforce not tested due to loack of hardware).

/* If we make it here we have succeeded in getting fresh work */
Revert "Rewrite the convoluted get_work() function to be much simpler and roll work as much as possible with each new work item." This reverts commit dec99ab739d16f2dd4f48482e713a25ebaef8e66. This seems to cause a race on work in free_work(). Presumably other threads are still accessing the structure.

Modularize code: main.c -> device-cpu + device-gpu This patch is an initial attempt to re-structure cgminer source code from its monolithic design (with nearly all code being concentrated in main.c) to a more modular one. In this first stage, the conditionally compiled functions for GPU and CPU mining were extracted into dedicated files: * device-cpu.h and device-cpu.c covering WANT_CPUMINE functions * device-gpu.h and device-gpu.c covering HAVE_OPENCL functions The main.c file is left untouched as reference, while the remainder without the extracted parts is located in cgminer.c. The Makefile.am has been updated to use the re-structured source files for the build. Above pure re-structuring *NO* functional modifications were made. The sources were tested to compile and run on on a current Linux system with working CPU and GPU mining (Bitforce not tested due to loack of hardware).

Modularize code: main.c -> device-cpu + device-gpu This patch is an initial attempt to re-structure cgminer source code from its monolithic design (with nearly all code being concentrated in main.c) to a more modular one. In this first stage, the conditionally compiled functions for GPU and CPU mining were extracted into dedicated files: * device-cpu.h and device-cpu.c covering WANT_CPUMINE functions * device-gpu.h and device-gpu.c covering HAVE_OPENCL functions The main.c file is left untouched as reference, while the remainder without the extracted parts is located in cgminer.c. The Makefile.am has been updated to use the re-structured source files for the build. Above pure re-structuring *NO* functional modifications were made. The sources were tested to compile and run on on a current Linux system with working CPU and GPU mining (Bitforce not tested due to loack of hardware).

Modularize code: main.c -> device-cpu + device-gpu This patch is an initial attempt to re-structure cgminer source code from its monolithic design (with nearly all code being concentrated in main.c) to a more modular one. In this first stage, the conditionally compiled functions for GPU and CPU mining were extracted into dedicated files: * device-cpu.h and device-cpu.c covering WANT_CPUMINE functions * device-gpu.h and device-gpu.c covering HAVE_OPENCL functions The main.c file is left untouched as reference, while the remainder without the extracted parts is located in cgminer.c. The Makefile.am has been updated to use the re-structured source files for the build. Above pure re-structuring *NO* functional modifications were made. The sources were tested to compile and run on on a current Linux system with working CPU and GPU mining (Bitforce not tested due to loack of hardware).
