Linux tables #21

zetalog · 2014-03-19T02:40:51Z

Let me try the github functionality.

There are 2 requirements reported from Linux community and we haven't
addressed all of them in ACPICA yet:

Mapping strategy for early boot stage
In Linux during early boot stages, there are booting code using ACPI
tables. During this stage, tables are mapped using early_ioremap(), the
pointers returned by this API are not safe to be used after this stage,
so the mapped pointers should not be stored in acpi_gbl_root_table_list.
This is handled with code invoking acpi_tb_delete_table() here and there
in ACPICA and a global variable acpi_gbl_permanent_mmap in Linux to
distinguish the 2 stages.
Freeing table mappings when no users
There are large tables in the world, it is not good always mapping them
in the virtual address space even there is no users interested in them.
But currently for Linux, it is impossible to achieve this, as the API
acpi_get_table() will always map the tables and never unmap them. So
if someone reads the ACPI tables accesible through Linux
/sys/firmware/acpi/tables, they will never get unmapped.

This patchset purifies the code in ACPICA that is supporting requirement 1
and implements requirement 2 by enfocing these rules:

ACPICA never fills acpi_table_desc.pointer if it is not interested in
this table (thus only tables containing definition blocks and FACS will
have this memeber filled).
ACPICA splits the state of acpi_table_desc stored in
acpi_gbl_root_table_list into "INSTALLED" and "VALIDATED":
"INSTALLED": in this state, acpi_table_desc.adress is valid and
acpi_table_desc.pointer is ensured to be NULL. So that ACPICA will
never be interested in the ACPI tables during early boot stage (i.e.,
during acpi_initialize_tables()).
"VALIDATED": in this state, acpi_table_desc.pointer is valid. Such
state will only appear during acpi_load_tables()/acpi_load_table()
and Load/LoadTable opcodes executions.

As code in ACPICA that is supporting requirement 1 is ambigious and easily
leaves bugs (some of them are fixed in this series), this patch makes
requirement 1 supporting code clearer by introducing the following APIs:

acpi_tb_install_table:
Table is in "INSTALLED" state after calling this function, thus
acpi_table_desc.pointer is NULL while acpi_table_desc.address is filled.
acpi_tb_uninstall_table:
The reversal of acpi_tb_install_table.
acpi_tb_validate_table:
Table is in "VALIDATED" state after calling this function, thus
acpi_table_desc.address and acpi_table_desc.pointer are all filled.
acpi_tb_invalidate_table:
The reversal of acpi_tb_invalidate_table.
acpi_tb_acquire_table:
When dealing with a acpi_table_header that is not maintained by
acpi_gbl_root_table_list, this internal API is used instead to make code
more readable.
acpi_tb_release_table:
The reversal of acpi_tb_acquire_table.
acpi_tb_override_table:
This function is renamed from acpi_tb_table_override(). Table is
remained in "INSTALLED" state after calling this function.
acpi_tb_verify_table:
This function is a combination of signature/checksum verification and
table validation. All tables are ensured to be verified before
installation and thus they are only validated after installation and
the verification needn't be called again.
The original acpi_tb_delete_table() invocations are replaced by either
acpi_tb_uninstall_table() or acpi_tb_invalidate_table() according to the
context where the original acpi_tb_delete_table() is invoked.
The original acpi_tb_verify_table() invocations are replaced by either
acpi_tb_verify_table() or acpi_tb_validate_table() according to the
context where the original acpi_tb_verify_table() is invoked.
The original acpi_tb_add_table() has been modified to accomodate to all
table loading invocations.

There are several trivial issues fixed in this patchset:

The acpi_table_desc.address is not synchronized with
acpi_table_desc.flags. Some ACPI_TABLE_ORIGIN_ALLOCATED address can not
be validated again after calling acpi_tb_delete_table().
There are memory leaks in acpi_tb_add_table().
There are redundant logics in acpi_tb_add_table() and
acpi_tb_parse_root_table() that can be merged.
Table checksums are not always been verified before installation.

After applying these series:
#1. ACPICA handles table states in the following style:

Stage Early - acpi_initialize_tables()

UNINSTALLED
acpi_tb_install_fixed_table(DSDT/FACS)/acpi_tb_install_non_fixed_table(others)
acpi_tb_verify_table(tmp_table_desc) <- checksums are verified only once and for all kinds of tables before installation
acpi_tb_validate_table(tmp_table_desc)
acpi_tb_override_table(tmp_table_desc) <- overrides happens before installation
acpi_tb_install_table(gbl_table_desc)
acpi_tb_invalidate_table(tmp_table_desc)

INSTALLED

Stage Late - acpi_load_tables()

INSTALLED (All non DSDT/SSDT/PSDT/OEM/FACS remains INSTALLED as ACPICA does
not use them)
acpi_tb_validate_table(gbl_table_desc of DSDT/SSDT/PSDT/OEM/FACS)

VALIDATED (only DSDT/SSDT/PSDT/OEM/FACS)

The patchset has been unit tested in AcpiExec by:

Initializing;
Executing exc_tbl ASLTS tests;
Executing "Load" command.
So that all original AcpiTbInstallTable() and AcpiTbOverrideTable()
invocations are covered.
It has also been linuxized and tested by booting an x86-64 machine with
CONFIG_ACPI enabled. There are "Load" opcodes executed in the kernel log.

When table is overridden or reloaded, AcpiTbDeleteTable() is called where ACPI_TABLE_DESC.Pointer will be NULL. It thus is impossible for virtual addressed tables to obtain the .Pointer again in AcpiTbVerifyTable(). This patch stores virtual table addresses (ACPI_TABLE_ORIGIN_ALLOCATED, ACPI_TABLE_ORIGIN_UNKNOWN, ACPI_TABLE_ORIGIN_OVERRIDE) in the ACPI_TABLE_DESC.Address field and refills the ACPI_TABLE_DESC.Pointer using these addresses in AcpiTbVerifyTable(). Note that if a table with ACPI_TABLE_ORIGIN_ALLOCATED set is actually freed, the .Address field should be invalidated and thus must be replaced with NULL to avoid wrong future validations occuring in AcpiTbVerifyTable().

… pointer around AcpiTbAddTable(). Currently there are following issues in AcpiTbAddTable(): Following logic is currently correct: 1. When a table is allocated in AcpiExLoadOp(), if a reloading happens, the allocated memory is freed by AcpiTbAddTable() and AE_OK is returned to the caller to avoid the caller to free it again. Following logic is currently incorrect: 1. When a table is allocated in AcpiExLoadOp() or by the AcpiLoadTable() caller, if the table is already loaded, there will be twice ACPI_FREE() called for the same pointer when AcpiTbAddTable() returns AE_ALREADY_EXISTS. This patch only fixes the above incorrect logic in AcpiTbAddTable(): 1. Only invoke AcpiTbDeleteTable() if AE_OK is going to be returned. 2. After doing so, we do not invoke ACPI_FREE() when returning AE_OK; Signed-off-by: Lv Zheng <lv.zheng@intel.com>

This patch is mainly a naming cleanup to clarify hidden logics, no functional changes. AcpiInitializeTables() 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 ACPI_TABLE_DESC structure during this stage. In order to support this in ACPICA, table states are divided into 1. "INSTALLED" (where ACPI_TABLE_DESC.Pointer is always NULL) and 2. "VALIDATED" (where ACPI_TABLE_DESC.Pointer is always not NULL). During AcpiInitializeTables(), 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 AcpiTb_DeleteTable() 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 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, ACPI_TABLE_DESC.Pointer will never be set in AcpiTbInstallTable() and AcpiTbOverrideTable() as they are the only functions invoked during AcpiInitializeTables(). This is achieved by: 1. Rename AcpiTbVerifyTable() to AcpiTbValidateTable() to clarify this change. 2. Rename AcpiTbTableOverride() to AcpiTbOverrideTable() to keep nameing consistencies as other APIs (verb. Table). 3. Stops setting ACPI_TABLE_DESC.Pointer in AcpiTbInstallTable() and AcpiTbTableOverride(). 4. Introduce AcpiTbAcquireTable() to acquire the table pointer that is not maintained in the ACPI_TABLE_DESC of the global root table list and rewrite AcpiTbValidateTable() using this new function to reduce redundancies. 5. Replace the table pointer using the overridden table pointer in AcpiTbAddTable(). As AcpiTbAddTable() is not invoked during early boot stage, tables returned from this functions should be "VALIDATED". As AcpiTbOverrideTable() is modified by this patch to return a "INSTALLED" but not "VALIDATED" descriptor, to keep AcpiTbAddTable() unchanged, ACPI_TABLE_DESC.Pointer is filled in AcpiTbAddTable(). B. For invalidation and uninstallation: The original code invalidate table by invoking AcpiTbDeleteTable() 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 AcpiTbDeleteTable() into AcpiTbInvalidateTable() and AcpiTbUninstallTable() and cleans up the hidden logic using the new APIs. This is achieved by: 1. Rename AcpiTbDeleteTable() to AcpiTbUninstallTable() as it is mainly called before resetting ACPI_TABLE_DESC.Address. Thus the table descriptor is in "not INSTALLED" state. This patch enforces this by setting ACPI_TABLE_DESC.Address to NULL in this function. 2. Introduce AcpiTbInvalidateTable() to be the reversal of AcpiTbValidateTable() and invoke it in AcpiTbUninstallTable(). 3. Introduce AcpiTbReleaseTable() to release the table pointer that is not maintained in AcpiGbl_RootTableList and rewrite AcpiTbInvalidateTable() using this new function to reduce redundancies. After cleaning up, the maintainability of the internal APIs are also improved: 1. AcpiTbAcquireTable: Acquire ACPI_TABLE_HEADER according to ACPI_TABLE_ORIGIN_xxx flags. 2. AcpiTbReleaseTable: Release ACPI_TABLE_HEADER according to ACPI_TABLE_ORIGIN_xxx flags. 3. AcpiTbInstallTable: Make ACPI_TABLE_DESC.Address not NULL according to ACPI_TABLE_ORIGIN_xxx flags. 4. AcpiTbUninstallTable: Make ACPI_TABLE_DESC.Address NULL according to ACPI_TABLE_ORIGIN_xxx flags. 5. AcpiTbValidateTable: Make ACPI_TABLE_DESC.Pointer not NULL according to ACPI_TABLE_ORIGIN_xxx flags. 6. AcpiTbInvalidateTable: Make ACPI_TABLE_DESC.Pointer NULL according to ACPI_TABLE_ORIGIN_xxx flags. 7. AcpiTbOverrideTable: Replace ACPI_TABLE_DESC.Address and ACPI_TABLE_DESC.Flags. It only happens in "INSTALLED" state. The patch has been unit tested in AcpiExec by: 1. Initializing; 2. Executing exc_tbl ASLTS tests; 3. Executing "Load" command. So that all original AcpiTbInstallTable() and AcpiTbOverrideTable() invocations are covered. Known Issues: 1. Cleanup AcpiTbAddTable() to Kill Code Redundancies Current implementation in AcpiTbAddTable() is not very clean, further patch can rewrite AcpiTbAddTable() with ordered AcpiTbInstallTable(), AcpiTbOverrideTable() and AcpiTbValidateTable(). It is not done in this patch so that it is easy for the reviewers to understand the changes in this patch. Signed-off-by: Lv Zheng <lv.zheng@intel.com>

As AcpiTbValidateTable() returns failure on checksum verification without doing invalidatation, all its invocations that are not done to a descriptor stored in AcpiGbl_RootTableList are checked and balanced. But this is not a real issue as the descritors that have been passed to AcpiTbAddTable() are all virtual address tables and the validations are in fact no-op. The cleanup can ensure that any future extensions made on AcpiTbAddTable() to allow it to be invoked with physical address tables will not trigger memory leakage regressions.

…fore installation. 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 AcpiTbInstallTable() and AcpiTbOverrideTable(), ACPI_TABLE_DESC.Pointer is ensured to be NULL. This can be safely used during OSPM's early boot stage. 2. "VALIDATED" after AcpiTbValidateTable(), ACPI_TABLE_DESC.Pointer is ensured to be not NULL. This must not be used during OSPM's early boot stage. This patch changes AcpiTbAddTable() 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 AcpiTbAddTable() 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 AcpiLoadTable() 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 AcpiTbInstallTable() to AcpiTbInstallFixedTable() as it only applies to DSDT/FACS installation. Rename AcpiTbAddTable() to AcpiTbInstallNonFixedTable() as it will be applied to the installation of the rest kinds of tables. 2. Introduce AcpiTbInstallTable(), AcpiTbInstallAndOverrideTable to collect redudant code where their invocations actually have slight differences. 1. AcpiTbInstallTable() is used to fill an ACPI_TABLE_DESC where the table length is known to the caller. 2. AcpiTbInstallAndOverrideTable() is used to perform necessary overriding before installation. 3. Change a parameter of AcpiTbInstallNonFixedTable() from ACPI_TABLE_DESC to ACPI_PHYSICAL_ADDRESS to allow it to be invoked by static table loadings. Also cleanup AcpiExLoadOp() and AcpiLoadTable() to accomodate to the parameter change. 4. Invoke AcpiTbInstallNonFixedTable() for all table loadings other than DSDT/FACS in AcpiTbParseRootTable() to improve code maintainability (logics are collected in the single function). Also delete useless code from AcpiTbParseRootTable(). 5. Remove all AcpiTbValidateTable() from AcpiTbInstallNonFixedTable() and AcpiTbInstallFixedTable() so that the table descriptor is kept in the state of "INSTALLED" but not "VALIDATED" after returning from these functions. 6. Introduce temporary ACPI_TABLE_DESC (NewTableDesc/OldTableDesc) into the functions to indicate a table descriptor that is not maintained by AcpiGbl_RootTableList. Introduce AcpiTbAcquireTemporalTable() and AcpiTbReleaseTemporalTable() to handle the use cases of such temporal tables. They are only used for verified installation. 7. Introduce AcpiTbVerifyTable() to validate table and verify table checksum, also remove table checksum verification from AcpiTbValidateTable(). Invoke AcpiTbValidateTable() in the functions that will convert a table into "LOADED" state or invoke it from AcpiGetTableXXX() APIs. Invoke AcpiTbVerifyTable() on temporary ACPI_TABLE_DESC(s) that are going to be "INSTALLED". 8. Change AcpiTbOverrideTable() logic so that a temporary 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. Signed-off-by: Lv Zheng <lv.zheng@intel.com>

This patch refines ACPI_TABLE_ORIGIN_xxx flags. No functional changes. The previous commits have introduced the following internal APIs: 1. AcpiTbAcquireTable: Acquire ACPI_TABLE_HEADER according to ACPI_TABLE_ORIGIN_xxx flags. 2. AcpiTbReleaseTable: Release ACPI_TABLE_HEADER according to ACPI_TABLE_ORIGIN_xxx flags. 3. AcpiTbInstallTable: Make ACPI_TABLE_DESC.Address not NULL according to ACPI_TABLE_ORIGIN_xxx flags. 4. AcpiTbUninstallTable: Make ACPI_TABLE_DESC.Address NULL according to ACPI_TABLE_ORIGIN_xxx flags. 5. AcpiTbValidateTable: Make ACPI_TABLE_DESC.Pointer not NULL according to ACPI_TABLE_ORIGIN_xxx flags. 6. AcpiTbInvalidateTable: Make 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".

…specified. It is reported that when AcpiGbl_DisableSsdtTableLoad 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 AcpiGbl_RootTableList. With previous cleanups, it is possible to prevent SSDT installations to make it not such confusing. The global variable is also renamed. Lv Zheng. Signed-off-by: Lv Zheng <lv.zheng@intel.com>
