* ACPICA: Tables: Fix global table list issues by removing fixed table indexesLv Zheng2015-08-251-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | ACPICA commit c0b38b4c3982c2336ee92a2a14716107248bd941 The fixed table indexes leave holes in the global table list: 1. One hole can be seen when there is only 1 FACS provided by the BIOS. 2. Tow holes can be seen when it is a reduced hardware platform. The holes do not break OSPMs but have broken ACPI debugger "tables" command. Also the "fixed table indexes" mechanism may make the descriptors of the standard tables installed earlier than DSDT to be overwritten by the descriptors of the fixed tables. For example, FACP disappears from the global table list after DSDT is installed. This patch fixes all above issues by removing the "fixed table indexes" mechanism which is too complicated to be maintained in a regression safe manner. After removal, the table loader will determine the indexes of the fixed tables. Lv Zheng.

* ACPICA: Tables: Enable both 32-bit and 64-bit FACSLv Zheng2015-07-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ACPICA commit f7b86f35416e3d1f71c3d816ff5075ddd33ed486 The following commit is reported to have broken s2ram on some platforms: Commit: 0249ed2444d65d65fc3f3f64f398f1ad0b7e54cd ACPICA: Add option to favor 32-bit FADT addresses. 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 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.

* ACPICA: Tables: Avoid SSDT installation with acpi_gbl_disable_ssdt_table_load.Lv Zheng2014-04-201-13/+0
| | | | | | | | | | | | | It is reported that when acpi_gbl_disable_ssdt_table_load is specified, user still can see it installed into /sys/firmware/acpi/tables on Linux boxes. This is because the option only stops table "loading", but doesn't stop table "installing", thus it is still in the acpi_gbl_root_table_list. With previous cleanups, it is possible to prevent SSDT installations to make it not such confusing. The global variable is also renamed. Lv Zheng.

* ACPICA: Tables: Cleanup ACPI_TABLE_ORIGIN_xxx flags.Lv Zheng2014-04-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch refines ACPI_TABLE_ORIGIN_xxx flags. No functional changes. The previous commits have introduced the following internal APIs: 1. acpi_tb_acquire_table: Acquire struct acpi_table_header according to ACPI_TABLE_ORIGIN_xxx flags. 2. acpi_tb_release_table: Release struct acpi_table_header according to ACPI_TABLE_ORIGIN_xxx flags. 3. acpi_tb_install_table: Make struct acpi_table_desc.Address not NULL according to ACPI_TABLE_ORIGIN_xxx flags. 4. acpi_tb_uninstall_table: Make struct acpi_table_desc.Address NULL according to ACPI_TABLE_ORIGIN_xxx flags. 5. acpi_tb_validate_table: Make struct acpi_table_desc.Pointer not NULL according to ACPI_TABLE_ORIGIN_xxx flags. 6. acpi_tb_invalidate_table: Make struct acpi_table_desc.Pointer NULL according to ACPI_TABLE_ORIGIN_xxx flags. It thus detects that the ACPI_TABLE_ORIGIN_UNKNOWN is redundant to ACPI_TABLE_ORIGIN_OVERRIDE. The ACPI_TABLE_ORIGIN_xxTERN_VIRTUAL flags are named as VIRTUAL in order not to confuse with x86 logical address, this patch also renames all "logical override" into "virtual override".

* ACPICA: Tables: Fix table checksums verification before installation.Lv Zheng2014-04-201-10/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original table handling code does not always verify checksums before installing a table, this is because code to achieve this must be implemented here and there in the redundant code blocks. There are two stages during table initialization: 1. "INSTALLED" after acpi_tb_install_table() and acpi_tb_override_table(), struct acpi_table_desc.Pointer is ensured to be NULL. This can be safely used during OSPM's early boot stage. 2. "VALIDATED" after acpi_tb_validate_table(), struct acpi_table_desc.Pointer is ensured to be not NULL. This must not be used during OSPM's early boot stage. This patch changes acpi_tb_add_table() into an early boot safe API to reduce code redundancies by changing the table state that is returned by this function from "VALIDATED" to "INSTALLED". Then the table verification code can be done in a single place. Originally, the acpi_tb_add_table() can only be used by dynamic table loadings that are executed after early boot stage, it cannot be used by static table loadings that are executed in early boot stage as: 1. The address of the table is a virtual address either maintained by OSPMs who call acpi_load_table() or by ACPICA whenever "Load" or "LoadTable" opcodes are executed, while during early boot stage, physical address of the table should be used for table loading. 2. The API will ensure the state of the loaded table to be "VALIDATED" while during early boot stage, tables maintained by root table list should be kept as "INSTALLED". To achieve this: 1. Rename acpi_tb_install_table() to acpi_tb_install_fixed_table() as it only applies to DSDT/FACS installation. Rename acpi_tb_add_table() to acpi_tb_install_non_fixed_table() as it will be applied to the installation of the rest kinds of tables. 2. Introduce acpi_tb_install_table(), acpi_tb_install_and_override_table to collect redudant code where their invocations actually have slight differences. 1. acpi_tb_install_table() is used to fill an struct acpi_table_desc where the table length is known to the caller. 2. acpi_tb_install_and_override_table() is used to perform necessary overriding before installation. 3. Change a parameter of acpi_tb_install_non_fixed_table() from struct acpi_table_desc to acpi_physical_address to allow it to be invoked by static table loadings. Also cleanup acpi_ex_load_op() and acpi_load_table() to accomodate to the parameter change. 4. Invoke acpi_tb_install_non_fixed_table() for all table loadings other than DSDT/FACS in acpi_tb_parse_root_table() to improve code maintainability (logics are collected in the single function). Also delete useless code from acpi_tb_parse_root_table(). 5. Remove all acpi_tb_validate_table() from acpi_tb_install_non_fixed_table() and acpi_tb_install_fixed_table() so that the table descriptor is kept in the state of "INSTALLED" but not "VALIDATED" after returning from these functions. 6. Introduce temporary struct acpi_table_desc (new_table_desc/old_table_desc) into the functions to indicate a table descriptor that is not maintained by acpi_gbl_root_table_list. Introduce acpi_tb_acquire_temporal_table() and acpi_tb_release_temporal_table() to handle the use cases of such temporal tables. They are only used for verified installation. 7. Introduce acpi_tb_verify_table() to validate table and verify table checksum, also remove table checksum verification from acpi_tb_validate_table(). Invoke acpi_tb_validate_table() in the functions that will convert a table into "LOADED" state or invoke it from acpi_get_table_XXX() APIs. Invoke acpi_tb_verify_table() on temporary struct acpi_table_desc(s) that are going to be "INSTALLED". 8. Change acpi_tb_override_table() logic so that a temporary struct acpi_table_desc will be overridden before installtion, this makes code simpler. After applying the patch, tables are always installed after being overridden and the table checksums are always verified before installation.

* ACPICA: Tables: Clean up split INSTALLED/VALIDATED table state logics.Lv Zheng2014-04-201-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is mainly a naming cleanup to clarify hidden logics, no functional changes. acpi_initialize_tables() is used by Linux to install table addresses for early boot steps. During this stage, table addresses are mapped by early_ioremap() mechanism which is different from the runtime IO mappings. Thus it is not safe for ACPICA to keep mapped pointers in struct acpi_table_desc structure during this stage. In order to support this in ACPICA, table states are divided into 1. "INSTALLED" (where struct acpi_table_desc.Pointer is always NULL) and 2. "VALIDATED" (where struct acpi_table_desc.Pointer is always not NULL). During acpi_initialize_tables(), table state are ensured to be "INSTALLED" but not "VALIDATED". This logic is ensured by the original code in very ambigious way. For example, currently acpi_tb_delete_table() is invoked in some place to perform an uninstallation while it is invoked in other place to perform an invalidation. They happen to work just because no one enters the penalty where the 2 behaviours are not equivalent. The naming cleanups are made in this patch: A. For installation and validation: There is code setting struct acpi_table_desc.Pointer first and delete it immediately to keep the descriptor's state as "INSTALLED" during the installation. This patch implements this in more direct way. After applying it, struct acpi_table_desc.Pointer will never be set in acpi_tb_install_table() and acpi_tb_override_table() as they are the only functions invoked during acpi_initialize_tables(). This is achieved by: 1. Rename acpi_tb_verify_table() to acpi_tb_validate_table() to clarify this change. 2. Rename acpi_tb_table_override() to acpi_tb_override_table() to keep nameing consistencies as other APIs (verb. Table). 3. Stops setting struct acpi_table_desc.Pointer in acpi_tb_install_table() and acpi_tb_table_override(). 4. Introduce acpi_tb_acquire_table() to acquire the table pointer that is not maintained in the struct acpi_table_desc of the global root table list and rewrite acpi_tb_validate_table() using this new function to reduce redundancies. 5. Replace the table pointer using the overridden table pointer in acpi_tb_add_table(). As acpi_tb_add_table() is not invoked during early boot stage, tables returned from this functions should be "VALIDATED". As acpi_tb_override_table() is modified by this patch to return a "INSTALLED" but not "VALIDATED" descriptor, to keep acpi_tb_add_table() unchanged, struct acpi_table_desc.Pointer is filled in acpi_tb_add_table(). B. For invalidation and uninstallation: The original code invalidate table by invoking acpi_tb_delete_table() here and there, but actually this function should only be used to uninstall tables. This can work just because its invocations are equivalent to invalidation in some cases. This patch splits acpi_tb_delete_table() into acpi_tb_invalidate_table() and acpi_tb_uninstall_table() and cleans up the hidden logic using the new APIs. This is achieved by: 1. Rename acpi_tb_delete_table() to acpi_tb_uninstall_table() as it is mainly called before resetting struct acpi_table_desc.Address. Thus the table descriptor is in "not INSTALLED" state. This patch enforces this by setting struct acpi_table_desc.Address to NULL in this function. 2. Introduce acpi_tb_invalidate_table() to be the reversal of acpi_tb_validate_table() and invoke it in acpi_tb_uninstall_table(). 3. Introduce acpi_tb_release_table() to release the table pointer that is not maintained in acpi_gbl_root_table_list and rewrite acpi_tb_invalidate_table() using this new function to reduce redundancies. After cleaning up, the maintainability of the internal APIs are also improved: 1. acpi_tb_acquire_table: Acquire struct acpi_table_header according to ACPI_TABLE_ORIGIN_xxx flags. 2. acpi_tb_release_table: Release struct acpi_table_header according to ACPI_TABLE_ORIGIN_xxx flags. 3. acpi_tb_install_table: Make struct acpi_table_desc.Address not NULL according to ACPI_TABLE_ORIGIN_xxx flags. 4. acpi_tb_uninstall_table: Make struct acpi_table_desc.Address NULL according to ACPI_TABLE_ORIGIN_xxx flags. 5. acpi_tb_validate_table: Make struct acpi_table_desc.Pointer not NULL according to ACPI_TABLE_ORIGIN_xxx flags. 6. acpi_tb_invalidate_table: Make struct acpi_table_desc.Pointer NULL according to ACPI_TABLE_ORIGIN_xxx flags. 7. acpi_tb_override_table: Replace struct acpi_table_desc.Address and struct acpi_table_desc.Flags. It only happens in "INSTALLED" state. The patch has been unit tested in acpi_exec by: 1. Initializing; 2. Executing exc_tbl ASLTS tests; 3. Executing "Load" command. So that all original acpi_tb_install_table() and acpi_tb_override_table() invocations are covered. Known Issues: 1. Cleanup acpi_tb_add_table() to Kill Code Redundancies Current implementation in acpi_tb_add_table() is not very clean, further patch can rewrite acpi_tb_add_table() with ordered acpi_tb_install_table(), acpi_tb_override_table() and acpi_tb_validate_table(). It is not done in this patch so that it is easy for the reviewers to understand the changes in this patch.

This changes can reduce source code differences between Linux and ACPICA upstream to help improving the release automation. The side effect of applying this patch in Linux is: 1. Some ACPICA initialization/termination APIs are no longer exported in Linux, these include: acpi_load_tables acpi_initialize_subsystem acpi_enable_subsystem acpi_initialize_objects acpi_terminate 2. This patch does not affect the following APIs as they are currently not marked with ACPI_EXPORT_SYMBOL in Linux: acpi_reallocate_root_table acpi_initialize_tables Such functions should not be exported as they are internal to ACPI subsystem in Linux, and will only be invoked inside of ACPI subsystem's initialization routines marked with __init and termination routines marked with __exit. While on other OSPMs, such functions may still need to be exported. Thus this patch adds the configurability for ACPICA, so that it leaves OSPMs to determine if the __init/__exit marked functions should be exported or not. Lv Zheng.

* ACPICA: Add option to disable loading of SSDTs from the RSDT/XSDTLv Zheng2013-06-161-15/+10
| | | | | | | | | | | | Optionally do not load any SSDTs from the RSDT/XSDT during initialization. This can be useful for overriding SSDTs using DSDT overriding, thus useful for debugging ACPI problems on some machines. Lv Zheng. ACPICA BZ 1005.
