ACPICA: Linuxize: Restore and fix Intel compiler build

2017-02-09T13:35:59Z

ACPICA commit b59347d0b8b676cb555fe8da5cad08fcd4eeb0d3 The following commit cleans up compiler specific inclusions: Commit: 9fa1cebdbfff3db8953cebca8ee327d75edefc40 Subject: ACPICA: OSL: Cleanup the inclusion order of the compiler-specific headers But breaks one thing due to the following old issue: Buidling Linux kernel with Intel compiler originally depends on acgcc.h not acintel.h. So after making Intel compiler build working in ACPICA upstream by correctly using acintel.h, it becomes unable to build Linux kernel using Intel compiler as there is no acintel.h in the kernel source tree. This patch releases acintel.h to Linux kernel and fixes its inclusion in acenv.h.

ACPICA: Tables: Back port acpi_get_table_with_size() and early_acpi_os_unmap_memory() from Linux kernel

2016-12-21T01:36:38Z

ACPICA commit cac6790954d4d752a083e6122220b8a22febcd07 This patch back ports Linux acpi_get_table_with_size() and early_acpi_os_unmap_memory() into ACPICA upstream to reduce divergences. The 2 APIs are used by Linux as table management APIs for long time, it contains a hidden logic that during the early stage, the mapped tables should be unmapped before the early stage ends. During the early stage, tables are handled by the following sequence: acpi_get_table_with_size(); parse the table early_acpi_os_unmap_memory(); During the late stage, tables are handled by the following sequence: acpi_get_table(); parse the table Linux uses acpi_gbl_permanent_mmap to distinguish the early stage and the late stage. The reasoning of introducing acpi_get_table_with_size() is: ACPICA will remember the early mapped pointer in acpi_get_table() and Linux isn't able to prevent ACPICA from using the wrong early mapped pointer during the late stage as there is no API provided from ACPICA to be an inverse of acpi_get_table() to forget the early mapped pointer. But how ACPICA can work with the early/late stage requirement? Inside of ACPICA, tables are ensured to be remained in "INSTALLED" state during the early stage, and they are carefully not transitioned to "VALIDATED" state until the late stage. So the same logic is in fact implemented inside of ACPICA in a different way. The gap is only that the feature is not provided to the OSPMs in an accessible external API style. It then is possible to fix the gap by providing an inverse of acpi_get_table() from ACPICA, so that the two Linux sequences can be combined: acpi_get_table(); parse the table acpi_put_table(); In order to work easier with the current Linux code, acpi_get_table() and acpi_put_table() is implemented in a usage counting based style: 1. When the usage count of the table is increased from 0 to 1, table is mapped and .Pointer is set with the mapping address (VALIDATED); 2. When the usage count of the table is decreased from 1 to 0, .Pointer is unset and the mapping address is unmapped (INVALIDATED). So that we can deploy the new APIs to Linux with minimal effort by just invoking acpi_get_table() in acpi_get_table_with_size() and invoking acpi_put_table() in early_acpi_os_unmap_memory().

ACPICA: OSL: Fix a regression that old GCC requires a workaround for strchr()

2016-08-13T01:16:39Z

ACPICA commit be836c36454a624a4fb1d17234080ef8c07993fc There is a GCC false-warning issue on specific GCC versions that "strchr" will be preprocessed and extracted to contain !__buildin_constant_p() checker and it surely is a constant logical value "1" for strchr() arguments. Then -Wlogical-op errorneously reports a warning. The regression is triggered after the standard headers are re-ordered in the EFI porting task. This patch fixes this regression by moving the workaround to a new position after including all other standard headers.
