2019-02-18ACPICA: Remove legacy module-level code supportErik Schmauss1-8/+0
ACPICA commit 47f5607c204719d9239a12b889df725225098c8f Module-level code refers to executable ASL code that runs during table load. This is typically used in ASL to declare named objects based on a condition evaluated during table load like so: definition_block(...) { opreation_region (OPR1, system_memory, ...) Field (OPR1) { FLD1, 8 /* Assume that FLD1's value is 0x1 */ } /* The if statement below is referred to as module-level code */ If (FLD1) { /* Declare DEV1 conditionally */ Device (DEV1) {...} } Device (DEV2) { ... } } In legacy module-level code, the execution of the If statement was deferred after other modules were loaded. The order of code execution for the table above is the following: 1.) Load OPR1 to the ACPI Namespace 2.) Load FLD1 to the ACPI Namespace (not intended for drivers) 3.) Load DEV2 to the ACPI Namespace 4.) Execute If (FLD1) and load DEV1 if the condition is true This legacy approach can be problematic for tables that look like the following: definition_block(...) { opreation_region (OPR1, system_memory, ...) Field (OPR1) { FLD1, 8 /* Assume that FLD1's value is 0x1 */ } /* The if statement below is referred to as module-level code */ If (FLD1) { /* Declare DEV1 conditionally */ Device (DEV1) {...} } Scope (DEV1) { /* Add objects DEV1's scope */ Name (OBJ1, 0x1234) } } When loading this in the legacy approach, Scope DEV1 gets evaluated before the If statement. The following is the order of execution: 1.) Load OPR1 to the ACPI Namespace 2.) Load FLD1 to the ACPI Namespace (not intended for drivers) 3.) Add OBJ1 under DEV1's scope -- ERROR. DEV1 does not exist 4.) Execute If (FLD1) and load DEV1 if the condition is true The legacy approach can never succeed for tables like this due to the deferral of the module-level code. Due to this limitation, a new module-level code was developed. This new approach exeutes if statements in the order that they appear in the definition block. With this approach, the order of execution for the above defintion block is as follows: 1.) Load OPR1 to the ACPI Namespace 2.) Load FLD1 to the ACPI Namespace (not intended for drivers) 3.) Execute If (FLD1) and load DEV1 because the condition is true 4.) Add OBJ1 under DEV1's scope. Since DEV1 is loaded in the namespace in step 3, step 4 executes successfully. This change removes support for the legacy module-level code execution. From this point onward, the new module-level code execution will be the official approach.

2019-02-07ACPI / APEI: Don't update struct ghes' flags in read/clear estatusJames Morse1-1/+0
ghes_read_estatus() sets a flag in struct ghes if the buffer of CPER records needs to be cleared once the records have been processed. This flag value is a problem if a struct ghes can be processed concurrently, as happens at probe time if an NMI arrives for the same error source. The NMI clears the flag, meaning the interrupted handler may never do the ghes_estatus_clear() work. The GHES_TO_CLEAR flags is only set at the same time as buffer_paddr, which is now owned by the caller and passed to ghes_clear_estatus(). Use this value as the flag. A non-zero buf_paddr returned by ghes_read_estatus() means ghes_clear_estatus() should clear this address. ghes_read_estatus() already checks for a read of error_status_address being zero, so CPER records cannot be written here.

2019-02-07ACPI / APEI: Don't store CPER records physical address in struct ghesJames Morse1-1/+0
When CPER records are found the address of the records is stashed in the struct ghes. Once the records have been processed, this address is overwritten with zero so that it won't be processed again without being re-populated by firmware. This goes wrong if a struct ghes can be processed concurrently, as can happen at probe time when an NMI occurs. If the NMI arrives on another CPU, the probing CPU may call ghes_clear_estatus() on the records before the handler had finished with them. Even on the same CPU, once the interrupted handler is resumed, it will call ghes_clear_estatus() on the NMIs records, this memory may have already been re-used by firmware. Avoid this stashing by letting the caller hold the address. A later patch will do away with the use of ghes->flags in the read/clear code too.

2019-02-07ACPI / APEI: Make estatus pool allocation a static sizeJames Morse1-1/+1
Adding new NMI-like notifications duplicates the calls that grow and shrink the estatus pool. This is all pretty pointless, as the size is capped to 64K.

2019-02-07ACPI / APEI: Make hest.c manage the estatus memory poolJames Morse1-0/+2
ghes.c has a memory pool it uses for the estatus cache and the estatus queue. The cache is initialised when registering the platform driver. For the queue, an NMI-like notification has to grow/shrink the pool as it is registered and unregistered. This is all pretty noisy when adding new NMI-like notifications, it would be better to replace this with a static pool size based on the number of users. As a precursor, move the call that creates the pool from ghes_init(), into hest.c. Later this will take the number of ghes entries and consolidate the queue allocations. Remove ghes_estatus_pool_exit() as hest.c doesn't have anywhere to put this. The pool is now initialised as part of ACPI's subsys_initcall(): (acpi_init(), acpi_scan_init(), acpi_pci_root_init(), acpi_hest_init()) Before this patch it happened later as a GHES specific device_initcall().

2018-10-18ACPICA: Remove acpi_gbl_group_module_level_code and only use ↵Erik Schmauss1-7/+0
acpi_gbl_execute_tables_as_methods instead acpi_gbl_group_module_level_code and acpi_gbl_execute_tables_as_methods were used to enable different table load behavior. The different table load behaviors are as follows: A.) acpi_gbl_group_module_level_code enabled the legacy approach where ASL if statements are executed after the namespace object has been loaded. B.) acpi_gbl_execute_tables_as_methods is currently used to enable the table load to be a method invocation. This meaning that ASL If statements are executed in-line rather than deferred until after the ACPI namespace has been populated. This is the correct behavior and option A will be removed in the future. We do not support a table load behavior where these variables are assigned the same value. In otherwords, we only support option A or B and do not need acpi_gbl_group_module_level_code to enable A. From now on, acpi_gbl_execute_tables_as_methods == 0 enables option A and acpi_gbl_execute_tables_as_methods == 1 enables option B. Note: option A is expected to be removed in the future and option B will become the only supported table load behavior. Signed-off-by: Erik Schmauss <erik.schmauss@intel.com> Signed-off-by: Rafael J.
