From 6895baa6a64fa9499e4d11696d59b3522c527ed0 Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Tue, 11 Apr 2017 15:48:05 +0800 Subject: ACPICA: Add non-linux host build support _LINUX: used to detect a target build is a linux kernel/application. __linux__: used to detect a build is on a linux hosts. Thus we can see: if a linux kernel build is performed on environments other than linux hosts, __linux__ may not be defined by the compiler and _LINUX cannot cover linux kernel resident ACPICA files, as it's only defined in and hence only allows non ACPICA kernel files to correctly include aclinux.h. As a conclusion, we don't actually support such build. This patch adds -D_LINUX for ACPICA files so that kernel builds on any hosts can use unified _LINUX as a linux kernel target indication to correctly include aclinux.h.

This causes the PWM controller to get hidden, which means Linux cannot control the backlight level on cht based tablets / laptops. Since loading the driver for this does no harm (the only in kernel user of it is the i915 driver, which will only uses it when it needs it), this commit makes acpi_bus_get_status() always set status to ACPI_STA_DEFAULT for the LPSS PWM device, fixing the lack of backlight control.

For the end_tag opcode, the second byte is defined to be either a checksum or zero. All known ASL compilers insert a zero for this byte. The disassembler now ensures this byte is zero before deciding that a buffer should be disassembled to a resource descriptor. This helps eliminate incorrect decisions when attempting to disassemble a buffer to a resource descriptor.

The function calls acpi_ns_terminate() function to delete namespace data and ACPI operand cache (acpi_gbl_module_code_list). But the deletion code in acpi_ns_terminate() function is wrapped in ACPI_EXEC_APP definition, therefore the code is only executed when the definition exists. If the define doesn't exist, ACPI operand cache (acpi_gbl_module_code_list) is leaked, and stack dump is shown in kernel log. This causes a security threat because the old kernel (<= 4.9) shows memory locations of kernel functions in stack dump, therefore kernel ASLR can be neutralized. To fix ACPI operand leak for enhancing security, I made a patch which removes the ACPI_EXEC_APP define in acpi_ns_terminate() function for executing the deletion code unconditionally.

Prevents invalid disassembly of AML created by older compilers (circa 2005).

On most devices this is not a problem as addresses above 0x34 are used for the BUC# convertors which are not used in the DSDTs I've access to but after the BUC# convertors there is a field named GPI1 in the DSTDs, which does get used in some cases and ended up turning BUC6 on and off due to the wrong addresses, resulting in turning the entire device off (or causing it to reboot). Removing the hole in the addresses fixes this, fixing one of my Bay Trail tablets turning off while booting the mainline kernel. While at it add comments with the field names used in the DSDTs to make it easier to compare the register and bits used at each address with the datasheet.

This is causing problems on a Dell Venue Pro 11 7130 (i5-4300Y) it causes the following messages to show up in dmesg: [ 131.014605] ACPI: Waking up from system sleep state S3 [ 131.150271] acpi LNXPOWER:07: Turning OFF [ 131.150323] acpi LNXPOWER:06: Turning OFF [ 131.150911] acpi LNXPOWER:00: Turning OFF [ 131.169014] ACPI : EC: interrupt unblocked [ 131.181811] xhci_hcd 0000:00:14.0: System wakeup disabled by ACPI [ 133.535728] pci_raw_set_power_state: 76 callbacks suppressed [ 133.535735] iwlwifi 0000:01:00.0: Refused to change power state, currently in D3 [ 133.597672] PM: noirq resume of devices complete after 2428.891 msecs Followed by a bunch of iwlwifi errors later on and the pcie device dropping from the bus (acpiphp thinks it has been unplugged). Disabling the turning off of unused power resources fixes this. Instead of adding a quirk for this system, this commit fixes this by moving the disabling of unused power resources to later in the resume sequence when the iwlwifi card has been moved out of D3 so the ref_count for its power resource no longer is 0. This new behavior seems to match the intend of the original commit which commit-msg says: "(... which means that no devices are going to need them any time soon) and we should turn them off". This also avoids power resources which we need when bringing devices out of D3 from getting bounced off and then back on again. Signed-off-by: Hans de Goede Signed-off-by: Rafael J.
