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.

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().

| | * | ACPI: Implement acpi_dma_configureLorenzo Pieralisi2016-11-291-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On DT based systems, the of_dma_configure() API implements DMA configuration for a given device. On ACPI systems an API equivalent to of_dma_configure() is missing which implies that it is currently not possible to set-up DMA operations for devices through the ACPI generic kernel layer. This patch fills the gap by introducing acpi_dma_configure/deconfigure() calls that for now are just wrappers around arch_setup_dma_ops() and arch_teardown_dma_ops() and also updates ACPI and PCI core code to use the newly introduced acpi_dma_configure/acpi_dma_deconfigure functions. Since acpi_dma_configure() is used to configure DMA operations, the function initializes the dma/coherent_dma masks to sane default values if the current masks are uninitialized (also to keep the default values consistent with DT systems) to make sure the device has a complete default DMA set-up. The DMA range size passed to arch_setup_dma_ops() is sized according to the device coherent_dma_mask (starting at address 0x0), mirroring the DT probing path behaviour when a dma-ranges property is not provided for the device being probed; this changes the current arch_setup_dma_ops() call parameters in the ACPI probing case, but since arch_setup_dma_ops() is a NOP on all architectures but ARM/ARM64 this patch does not change the current kernel behaviour on them.

Address this problem by making intel_pstate use the ACPI-defined mechanism as well. However, intel_pstate is not modular and it doesn't need the module refcount tricks played by acpi_processor_notify_smm(), so export the core of this function to it as acpi_processor_pstate_control() and make it call that. [The changes in processor_perflib.c related to this should not make any functional difference for the acpi_processor_notify_smm() users]. To be safe, only call acpi_processor_notify_smm() from intel_pstate if ACPI _PPC support is enabled in it.

The math for delivered performance per the CPPCv5.0+ spec is: reference perf * delta(delivered perf ctr)/delta(ref perf ctr) Maintaining deltas of the counters in the kernel is messy, as it depends on when the reads are triggered. (e.g. via the cpufreq ->get() interface). Also the ->get() interace only returns one value, so cant return raw values. So instead, leave it to userspace to keep track of raw values and do its math for CPUs it cares about. delivered and reference perf counters are exposed via the same sysfs file to avoid the potential "skid", if these values are read individually from userspace.

Currently the access to pcc is serialized by a spin lock which does not scale well as we increase the number of cores in the system. This patch improves the scalability by allowing the differnt CPU cores to update PCC subspace in parallel and by batching requests which will reduce the certain types of operation(checking command completion bit, ringing doorbell) by a significant margin. Profiling shows significant improvement in the overall effeciency to service freq. transition requests. With this patch we observe close to 30% of the frequency transition requests being batched with other requests while running apache bench on a ARM platform with 6 independent domains(or sets of related cpus).

The original implementation of MLC in ACPICA had several issues: 1. Out of any control method, besides of the object creating opcodes, only the code blocks wrapped by "If/Else/While" opcodes were supported. 2. The supported MLC code blocks were executed after loading the table rather than being executed right in place. ============================================================ The demo of this order issue is as follows: Name (OBJ1, 1) If (CND1 == 1) { Name (OBJ2, 2) } Name (OBJ3, 3) The original MLC support created OBJ2 after OBJ3's creation. ============================================================ Other than these limitations, MLC support in ACPICA looks correct. And supporting this should be easy/natural for ACPICA, but enabling of this was blocked by some ACPICA internal and OSPM specific initialization order issues we've fixed recently. The wrong support started from the following false bug fixing commit: Commit: 7f0c826a437157d2b19662977e9cf3b472cf24a6 Subject: ACPICA: Add support for module-level executable AML code Commit: 9a884ab64a4d092b4c3bf24fd9a30f7fbd4591e7 Subject: ACPICA: Add additional module-level code support ... We can confirm Windows interpreter behavior via reverse engineering means. It can be proven that not only If/Else/While wrapped code blocks, all opcodes can be executed at the module level, including operation region accesses. And it can be proven that the MLC should be executed right in place, not in such a deferred way executed after loading the table. And the above facts indeed reflect the spec words around ACPI definition block tables (DSDT/SSDT/...), the entire table and the Scope object is defined by the AML specification in BNF style as: AMLCode := def_block_header term_list def_scope := scope_op pkg_length name_string term_list The bodies of the scope opening terms (AMLCode/Scope) are all term_list, thus the table loading should be no difference than the control method evaluations as the body of the Method is also defined by the AML specification as term_list: def_method := method_op pkg_length name_string method_flags term_list The only difference is: after evaluating control method, created named objects may be freed due to no reference, while named objects created by the table loading should only be freed after unloading the table. So this patch follows the spec and the de-facto standard behavior, enables the new grammar (term_list) for the table loading. By doing so, beyond the fixes to the above issues, we can see additional differences comparing to the old grammar based table loading: 1. Originally, beyond the scope opening terms (AMLCode/Scope), If/Else/While wrapped code blocks under the scope creating terms (Device/power_resource/Processor/thermal_zone) are also supported as deferred MLC, which violates the spec defined grammar where object_list is enforced. With MLC support improved as non-deferred, the interpreter parses such scope creating terms as term_list rather object_list like the scope opening terms. After probing the Windows behavior and proving that it also parses these terms as term_list, we submitted an ECR (Engineering Change Request) to the ASWG (ACPI Specification Working Group) to clarify this. The ECR is titled as "ASL Grammar Clarification for Executable AML Opcodes" and has been accepted by the ASWG. The new grammar will appear in ACPI specification 6.2. 2. Originally, Buffer/Package/operation_region/create_XXXField/bank_field arguments are evaluated in a deferred way after loading the table. With MLC support improved, they are also parsed right in place during the table loading. This is also Windows compliant and the only difference is the removal of the debugging messages implemented before acpi_ds_execute_arguments(), see Link # [1] for the details. A previous commit should have ensured that acpi_check_address_range() won't regress. Note that enabling this feature may cause regressions due to long term Linux ACPI support on top of the wrong grammar. So this patch also prepares a global option to be used to roll back to the old grammar during the period between a regression is reported and the regression is root-cause-fixed. Lv Zheng.

* | ACPICA: OSL: Fix a regression that old GCC requires a workaround for strchr()Lv Zheng2016-08-133-12/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
