From 0d15414ed6c144f7f7e4ce63476b3eb9b94acceb Mon Sep 17 00:00:00 2001 From: Chris Johns Date: Wed, 5 Aug 2009 00:00:54 +0000 Subject: 009-08-05 Chris Johns * libmisc/dummy/dummy-networking.c: New. * libmisc/dummy/dummy.c, libmisc/Makefile.am: Move trhe networking configuration into a separate file so configuration varations do not cause conflicts. * score/inline/rtems/score/object.inl, score/include/rtems/score/object.h: Remove warnings. * score/inline/rtems/score/object.inl: Add _Chain_First, _Chain_Last, _Chain_Mext, and _Chain_Previous. * sapi/inline/rtems/chain.inl: Add rtems_chain_first, rtems_chain_last, rtems_chain_mext, and rtems_chain_previous. * libblock/include/rtems/diskdevs.h: Remove the bdbuf pool id and block_size_log2. Add media_block_size. * libblock/src/diskdevs.c: Remove size restrictions on block size. Add media block size initialisation. Remove comment to clean up the bdbuf cache. * libblock/src/blkdev.c: Remove references to block_size_log2. Allow any block size. * libblock/include/rtems/bdbuf.h, libblock/src/bdbuf.c: Remove all references to pools and make the cache handle demand driver variable buffer size allocation. Added worker threads support the swapout task. * sapi/include/confdefs.h: Updated the bdbuf configutation. --- cpukit/sapi/include/confdefs.h | 51 +++++++++++++++++++++++-------------- cpukit/sapi/inline/rtems/chain.inl | 52 +++++++++++++++++++++++++++++++++++++- 2 files changed, 83 insertions(+), 20 deletions(-) (limited to 'cpukit/sapi') diff --git a/cpukit/sapi/include/confdefs.h b/cpukit/sapi/include/confdefs.h index 6cc93086e0..c8f5c57d5d 100644 --- a/cpukit/sapi/include/confdefs.h +++ b/cpukit/sapi/include/confdefs.h @@ -727,32 +727,45 @@ rtems_fs_init_functions_t rtems_fs_init_helper = #define CONFIGURE_SWAPOUT_BLOCK_HOLD \ RTEMS_BDBUF_SWAPOUT_TASK_BLOCK_HOLD_DEFAULT #endif + #ifndef CONFIGURE_SWAPOUT_WORKER_TASKS + #define CONFIGURE_SWAPOUT_WORKER_TASKS \ + RTEMS_BDBUF_SWAPOUT_WORKER_TASKS_DEFAULT + #endif + #ifndef CONFIGURE_SWAPOUT_WORKER_TASK_PRIORITY + #define CONFIGURE_SWAPOUT_WORKER_TASK_PRIORITY \ + RTEMS_BDBUF_SWAPOUT_WORKER_TASK_PRIORITY_DEFAULT + #endif + #ifndef CONFIGURE_BDBUF_CACHE_MEMORY_SIZE + #define CONFIGURE_BDBUF_CACHE_MEMORY_SIZE \ + RTEMS_BDBUF_CACHE_MEMORY_SIZE_DEFAULT + #endif + #ifndef CONFIGURE_BDBUF_BUFFER_MIN_SIZE + #define CONFIGURE_BDBUF_BUFFER_MIN_SIZE \ + RTEMS_BDBUF_BUFFER_MIN_SIZE_DEFAULT + #endif + #ifndef CONFIGURE_BDBUF_BUFFER_MAX_SIZE + #define CONFIGURE_BDBUF_BUFFER_MAX_SIZE \ + RTEMS_BDBUF_BUFFER_MAX_SIZE_DEFAULT + #endif #ifdef CONFIGURE_INIT - rtems_bdbuf_config rtems_bdbuf_configuration = { + const rtems_bdbuf_config rtems_bdbuf_configuration = { CONFIGURE_BDBUF_MAX_READ_AHEAD_BLOCKS, CONFIGURE_BDBUF_MAX_WRITE_BLOCKS, CONFIGURE_SWAPOUT_TASK_PRIORITY, CONFIGURE_SWAPOUT_SWAP_PERIOD, - CONFIGURE_SWAPOUT_BLOCK_HOLD + CONFIGURE_SWAPOUT_BLOCK_HOLD, + CONFIGURE_SWAPOUT_WORKER_TASKS, + CONFIGURE_SWAPOUT_WORKER_TASK_PRIORITY, + CONFIGURE_BDBUF_CACHE_MEMORY_SIZE, + CONFIGURE_BDBUF_BUFFER_MIN_SIZE, + CONFIGURE_BDBUF_BUFFER_MAX_SIZE }; #endif - #ifndef CONFIGURE_HAS_OWN_BDBUF_TABLE - #ifndef CONFIGURE_BDBUF_BUFFER_COUNT - #define CONFIGURE_BDBUF_BUFFER_COUNT 64 - #endif - - #ifndef CONFIGURE_BDBUF_BUFFER_SIZE - #define CONFIGURE_BDBUF_BUFFER_SIZE 512 - #endif - #ifdef CONFIGURE_INIT - rtems_bdbuf_pool_config rtems_bdbuf_pool_configuration[] = { - {CONFIGURE_BDBUF_BUFFER_SIZE, CONFIGURE_BDBUF_BUFFER_COUNT, NULL} - }; - size_t rtems_bdbuf_pool_configuration_size = - (sizeof(rtems_bdbuf_pool_configuration) / - sizeof(rtems_bdbuf_pool_configuration[0])); - #endif /* CONFIGURE_INIT */ - #endif /* CONFIGURE_HAS_OWN_BDBUF_TABLE */ + #if defined(CONFIGURE_HAS_OWN_BDBUF_TABLE) || \ + defined(CONFIGURE_BDBUF_BUFFER_SIZE) || \ + defined(CONFIGURE_BDBUF_BUFFER_COUNT) + #error BDBUF Cache does not use a buffer configuration table.
