[PATCH V2 0/4] Convert GIC to ACPI

by Hanjun Guo

This patch set trys to convert GIC to ACPI which based on patches from Amit, I rework them and try to get things simpler. In MADT table, there are GIC cpu interface base address and GIC distributor base address, use them to convert GIC to ACPI. GIC should be converted after all the devices refer to GIC are converted. But this patch set can be safely applied to linaro-acpi git tree if we don't remove the DT node of GIC, the node of GIC can be removed after all the devices converted to ACPI. v2: a) fix missed iounmap() when return in error path; b) add stab for acpi_gic_init(void) when !CONFIG_ACPI C) modify the GSI mapping from DT to ACPI d) remove the hack code and modify the change log a bit Amit Daniel Kachhap (2): irqdomain: Add a new API irq_create_acpi_mapping() ACPI: ARM: Update acpi_register_gsi to register with the core IRQ subsystem Hanjun Guo (2): irqchip / GIC: do not set default host for GIC domain multi-times when ACPI enabled ARM / GIC: convert GIC to ACPI using the information in MADT arch/arm64/kernel/irq.c | 4 ++ drivers/acpi/plat/arm/boot.c | 98 ++++++++++++++++++++++++++++++++++++------ drivers/irqchip/irq-gic.c | 5 ++- include/linux/acpi.h | 8 ++++ kernel/irq/irqdomain.c | 27 ++++++++++++ 5 files changed, 127 insertions(+), 15 deletions(-) -- 1.7.9.5

[PATCH v2] ARM64 / ASL: Fix interrupt type and level flag for device interrupts

by Hanjun Guo

For gic bindings, The 3rd cell of interrupts is the flags,encoded as follows: bits[3:0] trigger type and level flags. 1 = low-to-high edge triggered 2 = high-to-low edge triggered 4 = active high level-sensitive 8 = active low level-sensitive bits[15:8] PPI interrupt cpu mask. Please refer to Documentation/devicetree/bindings/arm/gic.txt for detailed information. In Foundation model and RTSM model's device tree, the 3rd cell of interrupts of all devices is 4, so we should use active high level-sensitive in the DSDT table too when we convert the device to ACPI.

[PATCH 0/2] Cleanup unusable/unneeded ASL files

by al.stone＠linaro.org

From: Al Stone <ahs3(a)redhat.com> The Arndale and Foundation model ASL files included a bunch of template files that will either (a) never be used since they are x86 specific, or (b) are highly unlikely to ever be needed (e.g., the TPM2 table).

[PATCH] Foundation model / ASL: Fix level flags for device interrupts

by Hanjun Guo

For gic bindings, The 3rd cell of interrupts is the flags, encoded as follows: bits[3:0] trigger type and level flags. 1 = low-to-high edge triggered 2 = high-to-low edge triggered 4 = active high level-sensitive 8 = active low level-sensitive bits[15:8] PPI interrupt cpu mask. In Foundation model and RTSM model's device tree, the 3rd cell of interrupts of all devices is 4, so we should use active high level-sensitive in the DSDT table too when we convert the device to ACPI.

[PATCH v3 00/13] Hardware Reduced Mode cleanup for ACPI

by al.stone＠linaro.org

From: Al Stone <ahs3(a)redhat.com> This series of patches starts with Hanjun's patch to create a kernel config item for CONFIG_ACPI_REDUCED_HARDWARE [0]. Building on that, I then reviewed all of the code that touched any of several fields in the FADT that the OSPM is supposed to ignore when ACPI is in Hardware Reduced mode [1]. Any time there was a use of one of the fields to be ignored, I evaluated whether or not the code was implementing Hardware Reduced mode correctly. Similarly, for each the flags in the FADT flags field that are to be ignored in Hardware Reduced mode, the kernel code was again scanned for proper usage. The remainder of the patches are to fix all of the situations I could find where the kernel would not behave correctly in this ACPI mode. These are being submitted as an RFC to the linaro-acpi@ list so I can get some other eyes looking at them before sending them to linux-acpi@ where they really need to go. These seem to work just fine on the RTSM model for ARMv7, both with and without ACPI enabled, and with and without ACPI_REDUCED_HARDWARE enabled. However, there's no way I can think of or test all possible scenarios so feedback would be greatly appreciated. NB: these changes are only applicable to the LEG ACPI working tree. The macros in patch 1/13 will have to change for the linux-acpi tree. Changes for v3: -- Consistent use of #if (!ACPI_REDUCED_HARDWARE) -- Use of ACPI_HW_DEPENDENT_RETURN_{*} macros -- Simplify wherever possible Changes for v2: -- Change patch series title -- Add in the FACS global lock patch as further hardware reduced mode cleanup that is needed -- Remove whitespace change that should not have gotten in [1] Please see the ACPI Specification v5.0 for details on Hardware Reduced mode.

[RFC PATCH 0/3] ACPI: ARM AMBA bus connector resource

by brandon.anderson＠amd.com

From: Brandon Anderson <brandon.anderson(a)amd.com> This is a proposal for ACPI driver probing of the ARM AMBA devices currently listed under ‘iofpga’ in the RTSM dts file. The main addition is drivers/amba/acpi.c which fits the role of an AMBA bus ‘connector resource’ for ACPI using struct amba_device. I have not yet figured out the implementation details regarding clocks (handled in the dts file with clock-names). However, I have included a proposed ASL format for clock information in the DSDT example below. With the last patch that hacks the clock info, this prototype will run on the Foundation and RTSM models. These patches require Hanjun’s fixed-clock patches to be applied first on top of a Linaro ACPI kernel: https://git.linaro.org/gitweb?p=arm/acpi/leg-kernel.git;a=summary Please comment on both the concept and the implementation.

Even FFM is enabled, not all errors can be covered by firmware. Based on the fact, only memory/IO CE and IO UC errors can be handled well by firmware by now. For processer errors, as a fact, I never saw so-called CE errors, only UC, even fatal error. As a result, you will get a MCE. You can consider that firmware just *bypass* this kind of error. In some way, that's why eMCA happens as a successor. That's all. Otherwise I will cross the red line ;-).

[RFC PATCH 00/12] Hardware Reduced Mode Cleanup for FADT fields

by al.stone＠linaro.org

From: Al Stone <ahs3(a)redhat.com> This series of patches starts with Hanjun's patch to create a kernel config item for CONFIG_ACPI_REDUCED_HARDWARE [0]. Building on that, I then reviewed all of the code that touched any of several fields in the FADT that the OSPM is supposed to ignore when ACPI is in Hardware Reduced mode [1]. Any time there was a use of one of the fields to be ignored, I evaluated whether or not the code was implementing Hardware Reduced mode correctly. Similarly, for each the flags in the FADT flags field that are to be ignored in Hardware Reduced mode, the kernel code was again scanned for proper usage. The remainder of the patches are to fix all of the situations I could find where the kernel would not behave correctly in this ACPI mode. These are being submitted as an RFC to the linaro-acpi@ list so I can get some other eyes looking at them before sending them to linux-acpi@ where they really need to go. These seem to work just fine on the RTSM model for ARMv7, both with and without ACPI enabled, and with and without ACPI_REDUCED_HARDWARE enabled. However, there's no way I can think of or test all possible scenarios so feedback would be greatly appreciated. [1] Please see the ACPI Specification v5.0 for details on Hardware Reduced mode.

[RFC PATCH] ACPI: ARM/ARM64: ensure the ACPI FACS global_lock is never used in HW reduced mode

by al.stone＠linaro.org

From: Al Stone <ahs3(a)redhat.com> This patch is dependent on the CONFIG_ACPI_REDUCED_HARDWARE patch already being in place. It may even make sense to be part of that series. The FACS contains a global_lock that is never to be used in Hardware Reduced mode. Instead of taking chances, this patch takes out the macros used for the global_lock if we are in Hardware Reduced mode so that they cannot be used.

[RFC PATCH] ACPI: ASL for bus and devices enumeration

by naresh.bhat＠linaro.org

From: Naresh Bhat <naresh.bhat(a)linaro.org> The ASL code for SMB, FPGA, AMBA bus and the devices on the bus. The SMB and FPGA are represented as Module device. The container object that acts as a bus node in a namespace. It may contain child objects that are devices or buses. The module device is declared using the ACPI0004 hardware identifier (HID). The AMBA is represented as a separate device along with UART.

[RFC PATCH 0/5] Convert the fixed clock to ACPI

by Hanjun Guo

This is the RFC version for converting the fixed clock to ACPI. Since the ACPI namespace is ok at the very late stage of system boot, so I did some major change in boot sequence for the enumeration of fixed clock, amba bus and its child device. I think this part should be review carefully. For DT, it works well for armv8 foudation model after the change in boot sequence, but the UART and amba bus are dependent on the fixed clock, if I only convert the fixed clock to ACPI, UART will not work. So this is the RFC version and the UART will be converted together in next version. Hanjun Guo (5): Driver / clk: add platform driver for fixed clock ACPI / ARM64: Whitelist the ACPI ID for fixed clock ACPI / platform: add some comments for internel registry of _HID names ACPI / fixed-clock: Add ACPI driver for fixed clock Clk / fixed clock: Delay the enumeration of fixed clock and make it popssible for ACPI arch/arm64/kernel/setup.c | 2 +- drivers/acpi/acpi_platform.c | 7 ++-- drivers/clk/clk-fixed-rate.c | 78 +++++++++++++++++++++++++++++++++++++++++- 3 files changed, 82 insertions(+), 5 deletions(-) -- 1.7.9.5

APEI perf events notes

by Tomasz Nowicki

Hi, I am able to see APEI events (memory errors) via perft tool and now switch my context to others types of error. According to our plan, cache ECC error type would be next. I want to place tracepoints at the end of every available APEI error processing path (actually it is already done for memory errors). This way we RAS daemon could keep its eye on them. There would be of course more type of error coming from others ARM SoC peripherals. GHES driver is unrolling data structure to "Common Platform Error Record" and try to obtain error section (defined in UEFI spec). Cache ECC fall within "Processor Error Sections". Here appear problems since most of "Common Platform Error Records" are x86/IA64 oriented. So my proposals would be to: 1. Implement all available APEI errors as tracepoint that is: Processor and PCI errors 2. Mean time, create proposals for UEFI spec. toward "Common Platform Error Record" expansion for ARM architecture. This would require changing available structures and add new sections for SoC peripherals (USB, Ethernet etc.). 3. In turn, new sections for SoC peripherals in UEFI spec. would require ACPI spec. change as well, I mean new error sources for HEST table. 4. Once above proposals would be accept, we could fill in tracepoints for new error types. I would appreciate any input on this. Regards, Tomasz
