Len:
The following two item patch series fixes a calculation in
./drivers/acpi/tables/tbutils.c::acpi_tb_parse_root_table() that
determines how many ACPI table entries will be truncated when the
number of RSDT/XSDT entries is greater than the statically allocated
'initial_tables[]' array.
As currently implemented, the calculation will always yield a value
of 0. The following output shows the issue (Note the line with
"...: Truncating ..." which incorrectly indicates 0):
ACPI: RSDP 32A82014, 0024 (r2 HP )
ACPI: XSDT 32A82580, 0494 (r1 HP XXXXXX 0 1000013)
ACPI Error (tbinstal-0207): Resize of Root Table Array is not allowed [20070126]
ACPI Warning (tbutils-0519): Truncating 0 table entries! [20070126]
ACPI: FACP 32A6C000, 00F4 (r3 HP XXXXXX 0 HP 0)
ACPI: DSDT 32A52000, 8E83 (r2 HP XXXXXX 8 INTL 20061109)
...
With the patch applied, the output correctly shows the number of
(missing) truncated entries:
ACPI: RSDP 32A82014, 0024 (r2 HP )
ACPI: XSDT 32A82580, 0494 (r1 HP XXXXXX 0 1000013)
ACPI Error (tbinstal-0207): Resize of Root Table Array is not allowed [20070126]
ACPI Warning (tbutils-0519): Truncating 5 table entries! [20070126]
ACPI: FACP 32A6C000, 00F4 (r3 HP XXXXXX 0 HP 0)
ACPI: DSDT 32A52000, 8E83 (r2 HP XXXXXX 8 INTL 20061109)
...
[PATCH 1/2] fixes the truncation message related calculation.
[PATCH 2/2] is non-functional white space fixes - 80 column adherence -
for the same file.
The underlying code affected is common to both x86 and ia64. I have
tested the patch on an ia64 platform.
All comments welcome.
