[Devel] [RFC PATCH 0/7] ACPICA: Tables: Cleanup table sanity checks

[Lv Zheng <lv.zheng at intel.com>]

[-- Attachment #1: Type: text/plain, Size: 1757 bytes --]

Originally AML table sanity check is only done for Load opcode, as
acpi_tb_compare_tables() is only invoked in
acpi_tb_install_standard_table(). While LoadTable opcode cannot be covered
as it directly invokes acpi_tb_load_table() without invoking
acpi_tb_install_standard_table(). Furthermore, standard table load also
cannot be covered as acpi_ns_load_table() is invoked instead of
acpi_tb_install_standard_table() and acpi_tb_load_table().

So it becomes a problem if a duplicate table is in RSDT/XSDT, there is no
such check implemented for static load tables and LoadTable opcode.

This patchset combines code paths (in return reduces some redundant code
blocks and enhances checks/locks) so that duplicate table detection can be
applied to all cases.

Lv Zheng (7):
  ACPICA: Tables: Cleanup table handler invokers
  ACPICA: Tables: Add sanity check for load_table opcode
  ACPICA: Tables: Add sanity check for table install
  ACPICA: Tables: Fix an unwanted exception for table reloading
  ACPICA: Tables: Enable acpi_ut_is_aml_table() for all ACPICA modules
  ACPICA: Tables: Add sanity check for static table load
  ACPICA: Tables: Change table comparison using table header for static
    load tables
