      OpenCL: auto config two threads per GPU · e46226fa
      psychocrypt authored
      The auto config generates for AMD devices now by default two threads per GPU.
      
      - remove the savety 128MiB memory now only from the max available GPU memory not from the avaialble memory for one alloc call
      - extend the memory documentation in amd.txt

      OpenCL: thread interleaving · d8316f7d
      psychocrypt authored
      If two threads are using the same GPU device the start time of each hash round is optimized based on the average time needed to calculate a bunch of hashes.
      
      This way to optimize the hash rate was first introduced by @SChernykh. This implementation based on the implementation in xmrig but differen in the details.
      
      - introduce a new config option `interleave`
      - implement thread interleaving

      change load order for backends · cf959a1c
      psychocrypt authored
      If CUDA is loaded before AMD but no CUDA is available it can be happen that the embadded OpenCL code is empty.
      This is only an issue if the binary is builded static on a different system.

      NVIDIA: fix wrong number of threads · 954296ed
      psychocrypt authored
      In the cuda backend for monero we start always twice as much threads as needed.
      Those threads are than removed after the AES matrix is copied to the shared memory.
      Never the less it is the result of an copy past bug.
      
      - start correct number of threads for `monero`

      fix broken AMD OpenCL compile · 2a0d565b
      psychocrypt authored
      The AMD compiler for OpenCL shipped with the driver 14XX is broken
      and can not compile xmr-stak since the monero v8 changes are introduced.
      
      - workaround a simple compare.
      - add new device define `OPENCL_DRIVER_MAJOR`

      NVIDIA: support for multiple CUDA libs · 732b0e41
      psychocrypt authored
      Allow to ship the miner with multiple cuda backends those depends on different driver versions.
      This will allow to support Turing/Volta and old Fermi GPU within one release.
      
      - add support to search for the first working CUDA backend
      - add some more messages to support better debugging (if a user has some issues)

      NVIDIA: rename config option `comp_mode` · bd4a4c94
      psychocrypt authored
      The name `comp_mode` for a memoy load pattern if a bad choosen name.
      Therefore I changed it to `mem_mode` which also gives use the possibility
      to add new mode later if needed.
      
      - rename `comp_mode` to `mem_mode`
      - fix documentation

      fix right bitshift in `amd_bitalign` · b4387ac0
      psychocrypt authored
      In the current implementation the bit align is using signed integer which results in pulling in
      ones in the case the sign bit is set.
      
      - cast to unsigned integer before using bitshift

      CUDA: fix invalid results · ed2168b4
      psychocrypt authored
      If `comp_mode` is false the results on a windows platform will be invalid.
      The reason for that is that `ulong4` is in windows 16byte and in linux 32byte.
      
      thx @xmrig for finding and solving the issue

      fix crash with monero and strided_index · 1c0ef154
      psychocrypt authored
      Strided index 1 is not allowed for cryptonight_v8 and monero.
      In the case the dev pool is set to monero and the user tuned there settings for
      an other currency the miner will crash if strided index or memChunk is not
      fitting the requirement to mine monero.
      This PR detects wrong configurations and will set strided index and memChunk to a valid
      value but only for cryptonight_v8. The user pool settings will only be changed if monero or
      cryptonight_v8 is selected.
