From 263f4beceae0ec5602cb41e792c25ebe3ec49c97 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Mon, 7 Apr 2014 14:50:37 +0200 Subject: score: Statically initialize IO manager This simplifies the RTEMS initialization and helps to avoid a memory overhead. The workspace demands of the IO manager were not included in the workspace size estimate. This is also fixed as a side-effect. Update documentation and move "Specifying Application Defined Device Driver Table" to the section end. This sub-section is not that important for the user. Mentioning this at the beginning may lead to confusion. --- cpukit/sapi/include/rtems/io.h | 13 ++----------- 1 file changed, 2 insertions(+), 11 deletions(-) (limited to 'cpukit/sapi/include/rtems/io.h') diff --git a/cpukit/sapi/include/rtems/io.h b/cpukit/sapi/include/rtems/io.h index 799a30582d..ce750b0f69 100644 --- a/cpukit/sapi/include/rtems/io.h +++ b/cpukit/sapi/include/rtems/io.h @@ -250,18 +250,9 @@ rtems_status_code rtems_io_lookup_name( rtems_driver_name_t *device_info ) RTEMS_COMPILER_DEPRECATED_ATTRIBUTE; -SAPI_IO_EXTERN uint32_t _IO_Number_of_drivers; +extern const size_t _IO_Number_of_drivers; -SAPI_IO_EXTERN rtems_driver_address_table *_IO_Driver_address_table; - -/** - * @brief Initialization of device drivers. - * - * NOTE: The IO manager has been extended to support runtime driver - * registration.
