From 2d12b6b381ba059d5f92798f5ea739672a2f5fcf Mon Sep 17 00:00:00 2001 From: Lukas Wunner Date: Wed, 25 Nov 2015 21:19:55 +0100 Subject: ACPI / utils: Add acpi_dev_present() There's an idiom in use by 7 Linux drivers to detect the presence of a particular ACPI HID by walking the namespace with acpi_get_devices(). The callback passed to acpi_get_devices() is mostly identical across the drivers, leading to lots of duplicate code. Add acpi_dev_present(), the ACPI equivalent to pci_dev_present(), allowing us to deduplicate all that boilerplate in the drivers.

But some old BIOS only defined "_PS3" for the D3COLD device, such as ZPODD device. And old kernel also believes the device with "_PS3" is a D3COLD device. So, add some logics for supporting D3 COLD device with old BIOS which is compatible with earlier ACPI spec and kernel behavior.

Redirect output destination to console: no file redirection will be needed by an in-kernel debugger, there is even no file can be accessed when the debugger is running in the kernel mode. 2. Output command prompts: programs other than acpiexec can have different prompt characters and the prompt characters may be implemented as a special character sequence to form a char device IO protocol. 3. Command ready/complete handshake: OSPM debugger may wait more conditions to implement OSPM specific semantics (for example, FIFO full/empty conditions for O_NONBLOCK or IO open/close conditions). Leaving such OSPM specific stuffs in the ACPICA debugger core blocks Linux debugger IO driver implementation. Several new OSL APIs are provided by this patch: 1. acpi_os_initialize_command_signals: initialize command handshake mechanism or any other OSPM specific stuffs. 2. acpi_os_terminate_command_signals: reversal of acpi_os_initialize_command_signals. 3. acpi_os_wait_command_ready: putting debugger task into wait state when a command is not ready. OSPMs can terminate command loop by returning AE_CTRL_TERMINATE from this API. Normally, wait_event() or wait_for_multiple_object() may be used to implement this API. 4. acpi_os_notify_command_complete: putting user task into running state when a command has been completed. OSPMs can terminate command loop by returning AE_CTRL_TERMINATE from this API. Normally, wake_up() or set_event() may be used to implement this API. This patch also converts current command signaling implementation into a generic debugger layer (osgendbg.c) to be used by the existing OSPMs or acpiexec, in return, Linux can have chance to implement its own command handshake mechanism. This patch also implements acpiexec batch mode in a multi-threading mode comaptible style as a demo (this can be confirmed by configuring acpiexec into DEBUGGER_MULTI_THREADED mode where the batch mode is still working). Lv Zheng. Note that the OSPM specific command handshake mechanism is required by Linux kernel because: 1. Linux kernel trends to use wait queue to synchronize two threads, using mutexes to achieve that will cause false "dead lock" warnings. 2. The command handshake mechanism implemented by ACPICA is implemented in this way because of a design issue in debugger IO streaming. Debugger IO outputs are simply cached using a giant buffer, this should be tuned by Linux in the future. Signed-off-by: Lv Zheng Signed-off-by: Rafael J.

They actually will get executed in this situation. Although such executions are harmless if we can correctly make acpi_db_single_step() a runtime stub, users may still do not want to see the debugger print messages logged into OSPMs' kernel logs when a debugger driver is not loaded to enable the debugger during runtime. This patch fixes this issue by introducing new stub mechanism instead of ACPI_DEBUGGER_EXEC. Lv Zheng.

Known issue: 1. IO flush support acpi_os_notify_command_complete() and acpi_os_wait_command_ready() can be used by acpi_dbg module to implement .flush() filesystem operation. While this patch doesn't go that far. It then becomes userspace tool's duty now to flush old commands before executing new batch mode commands. Signed-off-by: Lv Zheng Signed-off-by: Rafael J.

Currently these driver use this construct for this: if (acpi_video_get_backlight_type() == acpi_backlight_vendor) report_brightness_key_event(); This indirect way of detecting if acpi-video is active does not make the code easier to understand, and in some cases it is wrong because just because the preferred type != vendor does not mean that acpi-video is actually listening for brightness events, e.g. there may be no acpi-video bus on the system at all. This commit adds a acpi_video_handles_brightness_key_presses() helper function, making the code needing this functionality both easier to read and more correct.

ACPICA commit e4743959b59ad93eab7310adf756adc930be0ddb This reverts commit 8e7a8753827660c3dd1f571f3185610402b756f0. The _SUB method was found to be problematic for this interface because some implementations use control methods. Therefore, it is being removed. Operations cannot be used because this interface is called during the device discovery scan and the region handlers are not fully installed at that time.

Wysocki Date: Mon, 4 Jan 2016 22:05:20 +0100 Subject: ACPICA: Drop Linux-specific waking vector functions Commit f06147f9fbf1 (ACPICA: Hardware: Enable firmware waking vector for both 32-bit and 64-bit FACS) added three functions that aren't present in upstream ACPICA, acpi_hw_set_firmware_waking_vectors(), acpi_set_firmware_waking_vectors() and acpi_set_firmware_waking_vector64(), to allow Linux to use the previously existing API for setting the platform firmware waking vector. However, that wasn't necessary, since the ACPI sleep support code in Linux can be modified to use the upstream ACPICA's API easily and the additional functions may be dropped which reduces the code size and puts the kernel's ACPICA code more in line with the upstream. Make the changes as per the above. While at it, make the relevant function desctiption comments reflect the upstream ACPICA's ones. Signed-off-by: Rafael J.
