[Qemu-devel] [PATCH for-2.10 0/5] tests: acpi: make sure FADT is compared to reference table

[Igor Mammedov]

While refactoring i386/FADT generation to build_append_int_noprefix()            
and testing it, It turned out that FADT is only tested for valid                 
checksum but actual test for unintended changes isn't applied to it              
even though we have reference tables in tree.                                    
So here goes a couple of cleanups to reflect what fuctions do +                  
some comments and actual fix.                                                    
                                                                                 
Note to maintainer:                                                              
  FADT reference table is out of sync and should be updated along with           
  series applied.

[Qemu-devel] [PATCH for-2.10 1/5] tests: acpi: move tested tables array allocation outside of test_acpi_dsdt_table()

[Igor Mammedov]

at best it's confusing that array for list of tables to be tested
against reference tables is allocated within test_acpi_dsdt_table()
and at worst it would just overwrite list of tables if they were
added before test_acpi_dsdt_table().
Move array initialization to test_acpi_one() before we start
processing tables.

[Qemu-devel] [PATCH for-2.10 3/5] tests: acpi: rename test_acpi_tables()/test_dst_table() to reflect its usage

[Igor Mammedov]

Main purpose of test_dst_table() is loading a table from QEMU
with checking that checksum in header matches actual one,
rename it reflect main action it performs.

Likewise test_acpi_tables() name is to broad, while the function
only loads tables referenced by RSDT, rename it to reflect it.

[Qemu-devel] [PATCH for-2.10 5/5] tests: acpi: fix FADT not being compared to reference table

[Igor Mammedov]

It turns out that FADT isn't actually tested for changes
against reference table, since it happens to be the 1st
table in RSDT which is currently ignored.
Fix it by making sure that all tables from RSDT are added
to test list.

Anyway, we should also add the expected file, right?

they are there see: tests/acpi-test-data/*/FACP
files obviously stale as they haven't been actually used.
Michael should update them when he applies this series.
