Previously we were only able to - use integer index to find the corresponding GPIO, which is pretty error - prone if the order changes. - - With _DSD we can now query GPIOs using name instead of an integer index, - like the below example shows: - - // Bluetooth device with reset and shutdown GPIOs - Device (BTH) - { - Name (_HID, ...) - - Name (_CRS, ResourceTemplate () - { - GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly, - "\\_SB.GPO0", 0, ResourceConsumer) {15} - GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly, - "\\_SB.GPO0", 0, ResourceConsumer) {27, 31} - }) - - Name (_DSD, Package () - { - ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), - Package () - { - Package () {"reset-gpio", Package() {^BTH, 1, 1, 0 }}, - Package () {"shutdown-gpio", Package() {^BTH, 0, 0, 0 }}, - } - }) - } - - The format of the supported GPIO property is: - - Package () { "name", Package () { ref, index, pin, active_low }} - - ref - The device that has _CRS containing GpioIo()/GpioInt() resources, - typically this is the device itself (BTH in our case). - index - Index of the GpioIo()/GpioInt() resource in _CRS starting from zero. - pin - Pin in the GpioIo()/GpioInt() resource. Typically this is zero. - active_low - If 1 the GPIO is marked as active_low. - - Since ACPI GpioIo() resource does not have field saying whether it is - active low or high, the "active_low" argument can be used here. Setting - it to 1 marks the GPIO as active low. - - In our Bluetooth example the "reset-gpio" refers to the second GpioIo() - resource, second pin in that resource with the GPIO number of 31. - - This patch implements necessary support to gpiolib for extracting GPIOs - using _DSD device properties. - - Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> - Acked-by: Linus Walleij <linus.walleij@linaro.org> - Acked-by: Grant Likely <grant.likely@linaro.org> - Signed-off-by: Rafael J.

With these properties one can pass - additional information to the drivers that would not be available - otherwise. - - ACPI is another configuration mechanism (among other things) typically - seen, but not limited to, x86 machines. ACPI allows passing arbitrary - data from methods but there has not been mechanism equivalent to Device - Tree until the introduction of _DSD in the recent publication of the - ACPI 5.1 specification. - - In order to facilitate ACPI usage in systems where Device Tree is - typically used, it would be beneficial to standardize a way to retrieve - Device Tree style properties from ACPI devices, which is what we do in - this patch. - - If a given device described in ACPI namespace wants to export properties it - must implement _DSD method (Device Specific Data, introduced with ACPI 5.1) - that returns the properties in a package of packages. For example: - - Name (_DSD, Package () { - ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), - Package () { - Package () {"name1", <VALUE1>}, - Package () {"name2", <VALUE2>}, - ... - } - }) - - The UUID reserved for properties is daffd814-6eba-4d8c-8a91-bc9bbf4aa301 - and is documented in the ACPI 5.1 companion document called "_DSD - Implementation Guide" [1], [2]. - - We add several helper functions that can be used to extract these - properties and convert them to different Linux data types. - - The ultimate goal is that we only have one device property API that - retrieves the requested properties from Device Tree or from ACPI - transparent to the caller. - - [1] http://www.uefi.org/sites/default/files/resources/_DSD-implementation-guide-toplevel.htm - [2] http://www.uefi.org/sites/default/files/resources/_DSD-device-properties-UUID.pdf - - Reviewed-by: Hanjun Guo <hanjun.guo@linaro.org> - Reviewed-by: Josh Triplett <josh@joshtriplett.org> - Reviewed-by: Grant Likely <grant.likely@linaro.org> - Signed-off-by: Darren Hart <dvhart@linux.intel.com> - Signed-off-by: Rafael J.

I'll - try to figure the rest out tomorrow.] - - Currently, we're accidentally ending up with executable stacks on - AArch64 when the ABI says we shouldn't be, and relying on glibc to fix - things up for us when we're loaded. However, SELinux will deny us - mucking with the stack, and hit us with execmem AVCs. - - The reason this is happening is somewhat complex: - - fs/binfmt_elf.c:load_elf_binary() - - initializes executable_stack = EXSTACK_DEFAULT implying the - architecture should make up its mind. - - does a pile of loading goo - - runs through the program headers, looking for PT_GNU_STACK - and setting (or unsetting) executable_stack if it finds it. - - This is our first problem, we won't generate these unless an - executable stack is explicitly requested. - - - more ELF loading goo - - sets whether we're a compat task or not (TIF_32BIT) based on compat.h - - for compat reasons (pre-GNU_STACK) checks if the READ_IMPLIES_EXEC - flag should be set for ancient toolchains - - Here's our second problem, we test if read_implies_exec based on - stk != EXSTACK_DISABLE_X, which is true since stk == EXSTACK_DEFAULT. - - So we set current->personality |= READ_IMPLIES_EXEC like a broken - legacy toolchain would want. - - - Now we call setup_arg_pages to set up the stack... - - fs/exec.c:setup_arg_pages() - - lots of magic happens here - - vm_flags gets initialized to VM_STACK_FLAGS - - Here's our third problem, VM_STACK_FLAGS on arm64 is - VM_DEFAULT_DATA_FLAG which tests READ_IMPLIES_EXEC and sets VM_EXEC - if it's true. So we end up with an executable stack mapping, since we - don't have executable_stack set (it's still EXSTACK_DEFAULT at this - point) to unset it anywhere. - - Bang. execstack AVC when the program starts running. - - The easiest way I can see to fix this is to test if we're a legacy task - and fix it up there. But that's not as simple as it sounds, because - the 32-bit ABI depends on what revision of the CPU we've enabled (not - that it matters since we're ARMv8...) Regardless, in the compat case, - set READ_IMPLIES_EXEC if we've found a GNU_STACK header which explicitly - requested it as in arch/arm/kernel/elf.c:arm_elf_read_implies_exec(). - - Signed-off-by: Kyle McMartin <kmcmarti@redhat.com> - Signed-off-by: Donald Dutile <ddutile@redhat.com> - -commit a68d368ceb495cabafe82cdd0b83ec1e271a7f9d -Author: Ard Biesheuvel <ard.biesheuvel@linaro.org> -Date: Fri Nov 7 14:12:34 2014 +0000 - - arm64: kvm: eliminate literal pool entries - - Replace two instances of 'ldr xN, =(constant)' in the world switch - hot path with 'mov' instructions. - - Acked-by: Marc Zyngier <marc.zyngier@arm.com> - Acked-by: Christoffer Dall <christoffer.dall@linaro.org> - Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> - Signed-off-by: Will Deacon <will.deacon@arm.com> - -commit 246a31b3a8f065e831a6d8d9fd96f3a8e17dbdb9 -Author: Ard Biesheuvel <ard.biesheuvel@linaro.org> -Date: Fri Nov 7 14:12:33 2014 +0000 - - arm64: ftrace: eliminate literal pool entries - - Replace ldr xN, =<symbol> with adrp/add or adrp/ldr [as appropriate] - in the implementation of _mcount(), which may be called very often. - - Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> - Signed-off-by: Will Deacon <will.deacon@arm.com> - -commit ecd0f8e21514e8ac758ed16a188faaa4c5ef75c7 -Author: Mark Rutland <mark.rutland@arm.com> -Date: Tue Nov 4 10:50:16 2014 +0000 - - arm64: log physical ID of boot CPU - - In certain debugging scenarios it's useful to know the physical ID (i.e. - the MPIDR_EL1.Aff* fields) of the boot CPU, but we don't currently log - this as we do for 32-bit ARM kernels. - - This patch makes the kernel log the physical ID of the boot CPU early in - the boot process.

Each struct acpi_gpio_params object consists of three fields, -+crs_entry_index, line_index, active_low, representing the index of the target -+GpioIo()/GpioInt() resource in _CRS starting from zero, the index of the target -+line in that resource starting from zero, and the active-low flag for that line, -+respectively, in analogy with the _DSD GPIO property format specified above. -+ -+For the example Bluetooth device discussed previously the data structures in -+question would look like this: -+ -+static const struct acpi_gpio_params reset_gpio = { 1, 1, false }; -+static const struct acpi_gpio_params shutdown_gpio = { 0, 0, false }; -+ -+static const struct acpi_gpio_mapping bluetooth_acpi_gpios[] = { -+ { "reset-gpio", &reset_gpio, 1 }, -+ { "shutdown-gpio", &shutdown_gpio, 1 }, -+ { }, -+}; -+ -+Next, the mapping table needs to be passed as the second argument to -+acpi_dev_add_driver_gpios() that will register it with the ACPI device object -+pointed to by its first argument.
