Detailed Description

Tests some Cache Manager directives.

This test case performs the following actions:

• Call the rtems_cache_disable_data() and rtems_cache_enable_data() directives.
• Call the rtems_cache_disable_data() and rtems_cache_enable_data() directives with maskable interrupts disabled.
• Call the rtems_cache_disable_instruction() and rtems_cache_enable_instruction() directives.
• Call the rtems_cache_disable_instruction() and rtems_cache_enable_instruction() directives with maskable interrupts disabled.
• Call the rtems_cache_freeze_data() and rtems_cache_unfreeze_data() directives.
• Call the rtems_cache_freeze_data() and rtems_cache_unfreeze_data() directives with maskable interrupts disabled.
• Call the rtems_cache_freeze_instruction() and rtems_cache_unfreeze_instruction() directives.
• Call the rtems_cache_freeze_instruction() and rtems_cache_unfreeze_instruction() directives with maskable interrupts disabled.
• Call the rtems_cache_invalidate_entire_data() directive with maskable interrupts disabled.
• Call the rtems_cache_invalidate_entire_instruction() directive.
• Call the rtems_cache_invalidate_entire_instruction() directive with maskable interrupts disabled.
• Call the rtems_cache_flush_entire_data() directive.
• Call the rtems_cache_flush_entire_data() directive with maskable interrupts disabled.
• Call the rtems_cache_flush_multiple_data_lines() directive with a sample set of memory areas.
• Call the rtems_cache_flush_multiple_data_lines() directive with a sample set of memory areas with maskable interrupts disabled.
• Call the rtems_cache_invalidate_multiple_data_lines() directive with a sample set of memory areas.
• Call the rtems_cache_invalidate_multiple_data_lines() directive with a sample set of memory areas with maskable interrupts disabled.
• Call the rtems_cache_invalidate_multiple_instruction_lines() directive with a sample set of memory areas.
• Call the rtems_cache_invalidate_multiple_instruction_lines() directive with a sample set of memory areas with maskable interrupts disabled.
• Call the rtems_cache_instruction_sync_after_code_change() directive with a sample set of memory areas.
• Call the rtems_cache_instruction_sync_after_code_change() directive with a sample set of memory areas with maskable interrupts disabled.
• Call the rtems_cache_get_data_line_size(), rtems_cache_get_instruction_line_size(), and the rtems_cache_get_maximal_line_size() directives.
  • Check that the maximal cache line size is greater than or equal to the data cache line size.
  • Check that the maximal cache line size is greater than or equal to the instruction cache line size.
• Call the rtems_cache_get_data_line_size(), rtems_cache_get_instruction_line_size(), and the rtems_cache_get_maximal_line_size() directives with maskable interrupts disabled.
  • Check that the maximal cache line size is greater than or equal to the data cache line size.
  • Check that the maximal cache line size is greater than or equal to the instruction cache line size.
• Call the rtems_cache_get_data_cache_size() directive with increasing level starting with zero until it returns zero.
• Call the rtems_cache_get_data_cache_size() directive with increasing level starting with zero until it returns zero with maskable interrupts disabled.
• Call the rtems_cache_get_instruction_cache_size() directive with increasing level starting with zero until it returns zero.
• Call the rtems_cache_get_instruction_cache_size() directive with increasing level starting with zero until it returns zero with maskable interrupts disabled.
