* ACPICA: Tables: Override all 64-bit GAS fields when ↵Lv Zheng2016-09-101-53/+49
| | | | | | | | | | | | | | | | | | | | | | | acpi_gbl_use32_bit_fadt_addresses is TRUE ACPICA commit aaace77db4c3b267a65b75c33f84ace6f65bbcf7 Originally, when acpi_gbl_use32_bit_fadt_addresses is TRUE, GAS override can only happen when the Address field mismatches. According to the investigation result, Windows may favor 32-bit FADT addresses in some cases. So we need this quirk working after enabling full GAS support. This requires us to override GAS access_size/bit_width/bit_offset fields as long as acpi_gbl_use32_bit_fadt_addresses is TRUE. This patch enhances this quirk mechanism to make it working with full GAS support. Lv Zheng.

Thus it is required to modify the linuxize result of this commit and the commits around it manually in order to have them merged to the Linux upstream.

* ACPICA: Tables: Fix FADT dependency regressionLv Zheng2015-10-141-5/+5
| | | | | | | | | | | | | | | | | | | | Some logics actually relying on the existence of FADT, currently relies on the number of loaded tables. This false dependency can easily trigger regressions. One of them has been introduced by commit 8ec3f459073e (ACPICA: Tables: Fix global table list issues by removing fixed table). The commit changing the fixed table indexes results in the change of FADT table index, originally, it was 3 (thus the installed table count should be greater than 4), while currently it is 0 (and the installed table count may be 3). This patch fixes this regression by cleaning up the code. Lv Zheng.

* ACPICA: Tables: Fix global table list issues by removing fixed table indexesLv Zheng2015-08-251-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | 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 Zheng2015-07-011-8/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Fix table checksums verification before installation.Lv Zheng2014-04-201-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Fix regression in FADT revision checksJulian Anastasov2012-03-211-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 64b3db22c04586997ab4be46dd5a5b99f8a2d390 (2.6.39), "Remove use of unreliable FADT revision field" causes regression for old P4 systems because now cst_control and other fields are not reset to 0. The effect is that acpi_processor_power_init will notice cst_control != 0 and a write to CST_CNT register is performed that should not happen. As result, the system oopses after the "No _CST, giving up" message, sometimes in acpi_ns_internalize_name, sometimes in acpi_ns_get_type, usually at random places. May be during migration to CPU 1 in acpi_processor_get_throttling. Every one of these settings help to avoid this problem: - acpi=off - processor.nocst=1 - maxcpus=1 The fix is to update acpi_gbl_FADT.header.length after the original value is used to check for old revisions. https://bugzilla.kernel.org/show_bug.cgi?id=42700 https://bugzilla.redhat.com/show_bug.cgi?id=727865 Signed-off-by: Julian Anastasov <ja@ssi.bg> Acked-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

* ACPICA: FADT: Favor 32-bit register addresses for compatibilityBob Moore2009-03-271-35/+51
| | | | | | | | | | | | | | | Use the 32-bit register addresses whenever they are non-zero. This means that the 32-bit addresses are favored over the 64-bit (GAS) addresses. The 64-bit addresses are only used if the 32-bit addresses are zero. This change provides compatibility with all versions of Windows. The worst case that this solves is when both the 32-bit and 64-bit addresses are non-zero, but only the 32-bit addresses are actually valid. This appears to happen in some BIOSes because in this case, Windows uses the 32-bit addresses.
