ACPI / scan: Fix enumeration for special SPI and I2C devices

2017-06-21T21:14:55Z

Commit f406270bf73d ("ACPI / scan: Set the visited flag for all enumerated devices") caused that two group of special SPI or I2C devices do not enumerate. SPI and I2C devices are expected to be enumerated by the SPI and I2C subsystems but change caused that acpi_bus_attach() marks those devices with acpi_device_set_enumerated(). First group of devices are matched using Device Tree compatible property with special _HID "PRP0001". Those devices have matched scan handler, acpi_scan_attach_handler() retuns 1 and acpi_bus_attach() marks them with acpi_device_set_enumerated(). Second group of devices without valid _HID such as "LNXVIDEO" have device->pnp.type.platform_id set to zero and change again marks them with acpi_device_set_enumerated(). Fix this by flagging the SPI and I2C devices during struct acpi_device object initialization time and let the code in acpi_bus_attach() to go through the device_attach() and acpi_default_enumeration() path for all SPI and I2C devices.

ACPICA: Tables: Mechanism to handle late stage acpi_get_table() imbalance

2017-06-12T12:09:29Z

Considering this case: 1. A program opens a sysfs table file 65535 times, it can increase validation_count and first increment cause the table to be mapped: validation_count = 65535 2. AML execution causes "Load" to be executed on the same table, this time it cannot increase validation_count, so validation_count remains: validation_count = 65535 3. The program closes sysfs table file 65535 times, it can decrease validation_count and the last decrement cause the table to be unmapped: validation_count = 0 4. AML code still accessing the loaded table, kernel crash can be observed. To prevent that from happening, add a validation_count threashold. When it is reached, the validation_count can no longer be incremented/decremented to invalidate the table descriptor (means preventing table unmappings) Note that code added in acpi_tb_put_table() is actually a no-op but changes the warning message into a "warn once" one.

Pull more ACPI updates from Rafael Wysocki: "These update the ACPICA code in the kernel to upstream revision 20170303 which adds a few minor fixes and improvements, update ACPI SoC drivers with new device IDs, platform-related information and similar, fix the register information in the xpower PMIC driver, introduce a concept of "always present" devices to the ACPI device enumeration code and use it to fix a problem with one platform, and fix a system resume issue related to power resources. Specifics: - Update the ACPICA code in the kernel to upstream revision 20170303 which includes: * Minor fixes and improvements in the core code (Bob Moore, Seunghun Han). * Debugger fixes (Colin Ian King, Lv Zheng). * Compiler/disassembler improvements (Bob Moore, David Box, Lv Zheng). * Build-related update (Lv Zheng). - Add new device IDs and platform-related information to the ACPI drivers for Intel (LPSS) and AMD (APD) SoCs (Hanjun Guo, Hans de Goede). - Make it possible to quirk ACPI-enumerated devices as "always present" on platforms where they are incorrectly reported as not present by the AML and add the INT0002 device ID to the list of "always present" devices (Hans de Goede). - Fix the register information in the xpower PMIC driver and add comments to map the registers to symbols used by AML to it (Hans de Goede). - Move the code turning off unused ACPI power resources during system resume to a point after all devices have been resumed to avoid issues with power resources that do not behave as expected (Hans de Goede)" * tag 'acpi-extra-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (22 commits) ACPI / power: Delay turning off unused power resources after suspend ACPI / PMIC: xpower: Fix power_table addresses ACPI / LPSS: Call pwm_add_table() for Bay Trail PWM device ACPICA: Update version to 20170303 ACPICA: iasl: add ASL conversion tool ACPICA: Local cache support: Allow small cache objects ACPICA: Disassembler: Do not unconditionally remove temporary names ACPICA: iasl: Fix IORT SMMU GSI disassembling ACPICA: Cleanup AML opcode definitions, no functional change ACPICA: Debugger: Add interpreter blocking mark for single-step mode ACPICA: debugger: fix memory leak on Pathname ACPICA: Update for automatic repair code for objects returned by evaluate_object ACPICA: Namespace: fix operand cache leak ACPICA: Fix several incorrect invocations of ACPICA return macro ACPICA: Fix a module for excessive debug output ACPICA: Update some function headers, no funtional change ACPICA: Disassembler: Enhance resource descriptor detection i2c: designware: Add ACPI HID for Hisilicon Hip07/08 I2C controller ACPI / APD: Add clock frequency for Hisilicon Hip07/08 I2C controller ACPI / bus: Add INT0002 to list of always-present devices ...
