Replace C library macros such as ACPI_STRLEN with the standard names such as strlen. The original purpose for these macros is long since obsolete. Also cast various invocations as necessary.

ACPICA commit ab29013cfa2424140446aff196a70b211ab343a9 The /dev/mem can be configured out, in which case, acpidump should still work with "-c" option as tables can be found in /sys/firmware/acpi/tables. This patch allows acpidump to work without /dev/mem. This patch has been tested with "acpidump -c" and "acpidump -c -n FADT". And it worked as expected. Lv Zheng.

ACPICA commit 5d00e67a74542d030f0a55e7a947a020ef0d9693 This patch copies EFI interface definitions to the ACPICA code base so that the EFI utility support can be ported to other EFI implementation. Known issues: 1. MS Builds of uefi_call_wrapper() The uefi_call_wrapper() in GNU EFI is implemented in a the way to work around the ABI difference between Unix and MS. While I don't have environment to test the MS builds. In order to port the ACPICA utilities to other EFI implementation, all that need to be done is to impelement the 64-bit division support and the program entry point where the efi_main() is invoked. Code to impelement these is platform specific, and ACPICA currently choose to hide such platform specific code within the specific EFI impelementation. Lv Zheng.

The platform reports 2 FACS tables (which is not allowed by ACPI specification) and the new 32-bit address favor rule forces OSPMs to use the FACS table reported via FADT's X_FIRMWARE_CTRL field. The root cause of the reported bug might be one of the followings: 1. BIOS may favor the 64-bit firmware waking vector address when the version of the FACS is greater than 0 and Linux currently only supports resuming from the real mode, so the 64-bit firmware waking vector has never been set and might be invalid to BIOS while the commit enables higher version FACS. 2. BIOS may favor the FACS reported via the "FIRMWARE_CTRL" field in the FADT while the commit doesn't set the firmware waking vector address of the FACS reported by "FIRMWARE_CTRL", it only sets the firware waking vector address of the FACS reported by "X_FIRMWARE_CTRL". This patch excludes the cases that can trigger the bugs caused by the root cause 2. There is no handshaking mechanism can be used by OSPM to tell BIOS which FACS is currently used. Thus the FACS reported by "FIRMWARE_CTRL" may still be used by BIOS and the 0 value of the 32-bit firmware waking vector might trigger such failure. This patch enables the firmware waking vectors for both 32bit/64bit FACS tables in order to ensure we can exclude the cases that trigger the bugs caused by the root cause 2. The exclusion is split into 2 commits so that if it turns out not to be necessary, this single commit can be reverted without affecting the useful one. Lv Zheng, Bob Moore.

This patch tries to favor 32bit FACS address in another way where both the FACS reported by "FIRMWARE_CTRL" and the FACS reported by "X_FIRMWARE_CTRL" are loaded so that further commit can set firmware waking vector in the both tables to ensure we can exclude the cases that trigger the bugs caused by the root cause 2. The exclusion is split into 2 commits as this commit is also useful for dumping more ACPI tables, it won't get reverted when such exclusion is no longer necessary. Lv Zheng.

This patch excludes the cases that can trigger the bugs caused by the root cause 1. ACPI specification says: A. 32-bit FACS address (FIRMWARE_CTRL field in FADT): Physical memory address of the FACS, where OSPM and firmware exchange control information. If the X_FIRMWARE_CTRL field contains a non zero value then this field must be zero. A zero value indicates that no FACS is specified by this field. B. 64-bit FACS address (X_FIRMWARE_CTRL field in FADT): 64bit physical memory address of the FACS. This field is used when the physical address of the FACS is above 4GB. If the FIRMWARE_CTRL field contains a non zero value then this field must be zero. A zero value indicates that no FACS is specified by this field. Thus the 32bit and 64bit firmware waking vector should indicate completely different resuming environment - real mode (1MB addressable) and non real mode (4GB+ addressable) and currently Linux only supports resuming from real mode. This patch enables 64-bit firmware waking vector for selected FACS via new acpi_set_firmware_waking_vectors() API so that it's up to OSPMs to determine which resuming mode should be used by BIOS and ACPICA changes won't trigger the bugs caused by the root cause 1.
