ACPI / OSL: Add support to install tables via initrd

2016-03-09T22:55:02+00:00

This patch adds support to install tables from initrd. If a table in the initrd wasn't used by the override mechanism, the table would be installed after initializing all RSDT/XSDT tables.

ACPI: Add acpi_force_32bit_fadt_addr option to force 32 bit FADT addresses

2016-03-09T22:46:07+00:00

Some HP laptops seem to have invalid 64 bit FADT X_PM* addresses which are causing various boot issues. In these cases, it would be useful to force ACPI to use the valid legacy 32 bit equivalent PM addresses. Add a acpi_force_32bit_fadt_addr to set the ACPICA acpi_gbl_use32_bit_fadt_addresses to TRUE to force this override.

ACPI / tables: test the correct variable

2015-10-14T23:31:24+00:00

The intent was to test "proc[i].handler" instead of "proc->handler". Signed-off-by: Dan Carpenter Signed-off-by: Rafael J. Wysocki

ACPI / tables: Add acpi_subtable_proc to ACPI table parsers

2015-10-14T23:29:39+00:00

ACPI subtable parsing needs to be extended to allow two or more handlers to be run in the same ACPI table walk, thus adding acpi_subtable_proc structure which stores () ACPI table id () handler that processes table () counter how many items has been processed and passing it to acpi_parse_entries_array() and acpi_table_parse_entries_array(). This is needed to fix CPU enumeration when APIC/X2APIC entries are interleaved. Signed-off-by: Lukasz Anaczkowski Reviewed-by: Marc Zyngier Tested-by: Marc Zyngier Signed-off-by: Rafael J. Wysocki

ACPI: Remove FSF mailing addresses

2015-07-08T00:27:32+00:00

There is no need to carry potentially outdated Free Software Foundation mailing address in file headers since the COPYING file includes it. Signed-off-by: Jarkko Nikula Signed-off-by: Rafael J. Wysocki

ACPI / table: Print GIC information when MADT is parsed

2015-03-25T11:49:31+00:00

When MADT is parsed, print GIC information as debug message: ACPI: GICC (acpi_id[0x0000] address[00000000e112f000] MPIDR[0x0] enabled) ACPI: GICC (acpi_id[0x0001] address[00000000e112f000] MPIDR[0x1] enabled) ... ACPI: GICC (acpi_id[0x0201] address[00000000e112f000] MPIDR[0x201] enabled) This debug information will be very helpful to bring up early systems to see if acpi_id and MPIDR are matched or not as spec defined.

ACPI / table: Use pr_debug() instead of pr_info() for MADT table scanning

2015-03-25T11:49:30+00:00

For a normal 8 cpu sockets system, it will up to 240 cpu threads (Xeon E7 v2 family for now), and we need 240 entries for local apic or local x2apic in MADT table, so it will be much verbose information printed with a slow uart console when system booted, this will be even worse with large system with 16/32 cpu sockets. This patch just use pr_debug() instead of pr_info() for ioapic/iosapic, local apic/x2apic/sapic structures when scanning the MADT table to remove those verbose information, but leave other structures unchanged.

ACPI / table: Always count matched and successfully parsed entries

2014-11-27T01:07:41+00:00

acpi_parse_entries() allows to traverse all available table entries (aka subtables) by passing max_entries parameter equal to 0, but since its count variable is only incremented if max_entries is not 0, the function always returns 0 for max_entries equal to 0. It would be more useful if it returned the number of entries matched instead, so make it increment count in that case too.

ACPI / table: Add new function to get table entries

2014-11-27T01:06:17+00:00

The acpi_table_parse() function has a callback that passes a pointer to a table_header. Add a new function which takes this pointer and parses its entries. This eliminates the need to re-traverse all the tables for each call. e.g. as in acpi_table_parse_madt() which is normally called after acpi_table_parse().
