[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.

by al.stone＠linaro.org

From: Al Stone <ahs3(a)redhat.com> In order to make the ASL files that have been created more usable to a wider audience, we found it necessary to change the distribution license from GPLv2 to the less restrictive BSD 2-clause license.

[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). Even if they ever do become needed, templates can easily be regenerated using the ACPICA iasl tool. So, remove these ASL files to introduce a little more clarity. Al Stone (2): Remove all Arndale ASL files that should never be used. Remove all Foundation model ASL files that should never be used. platforms/exynos5250-arndale.acpi/dbgp.asl | 29 ---------- platforms/exynos5250-arndale.acpi/dmar.asl | 68 ----------------------- platforms/exynos5250-arndale.acpi/hpet.asl | 33 ------------ platforms/exynos5250-arndale.acpi/ivrs.asl | 86 ------------------------------ platforms/exynos5250-arndale.acpi/s3pt.asl | 26 --------- platforms/exynos5250-arndale.acpi/sbst.asl | 22 -------- platforms/exynos5250-arndale.acpi/slic.asl | 56 ------------------- platforms/exynos5250-arndale.acpi/spcr.asl | 46 ---------------- platforms/exynos5250-arndale.acpi/tcpa.asl | 22 -------- platforms/exynos5250-arndale.acpi/tpm2.asl | 22 -------- platforms/exynos5250-arndale.acpi/waet.asl | 22 -------- platforms/exynos5250-arndale.acpi/wdat.asl | 47 ---------------- platforms/exynos5250-arndale.acpi/wddt.asl | 44 --------------- platforms/exynos5250-arndale.acpi/wdrt.asl | 42 --------------- platforms/foundation-v8.acpi/dbgp.asl | 29 ---------- platforms/foundation-v8.acpi/dmar.asl | 68 ----------------------- platforms/foundation-v8.acpi/hpet.asl | 33 ------------ platforms/foundation-v8.acpi/ivrs.asl | 86 ------------------------------ platforms/foundation-v8.acpi/s3pt.asl | 26 --------- platforms/foundation-v8.acpi/sbst.asl | 22 -------- platforms/foundation-v8.acpi/slic.asl | 56 ------------------- platforms/foundation-v8.acpi/spcr.asl | 46 ---------------- platforms/foundation-v8.acpi/tcpa.asl | 22 -------- platforms/foundation-v8.acpi/tpm2.asl | 22 -------- platforms/foundation-v8.acpi/waet.asl | 22 -------- platforms/foundation-v8.acpi/wdat.asl | 47 ---------------- platforms/foundation-v8.acpi/wddt.asl | 44 --------------- platforms/foundation-v8.acpi/wdrt.asl | 42 --------------- 28 files changed, 1130 deletions(-) delete mode 100644 platforms/exynos5250-arndale.acpi/dbgp.asl delete mode 100644 platforms/exynos5250-arndale.acpi/dmar.asl delete mode 100644 platforms/exynos5250-arndale.acpi/hpet.asl delete mode 100644 platforms/exynos5250-arndale.acpi/ivrs.asl delete mode 100644 platforms/exynos5250-arndale.acpi/s3pt.asl delete mode 100644 platforms/exynos5250-arndale.acpi/sbst.asl delete mode 100644 platforms/exynos5250-arndale.acpi/slic.asl delete mode 100644 platforms/exynos5250-arndale.acpi/spcr.asl delete mode 100644 platforms/exynos5250-arndale.acpi/tcpa.asl delete mode 100644 platforms/exynos5250-arndale.acpi/tpm2.asl delete mode 100644 platforms/exynos5250-arndale.acpi/waet.asl delete mode 100644 platforms/exynos5250-arndale.acpi/wdat.asl delete mode 100644 platforms/exynos5250-arndale.acpi/wddt.asl delete mode 100644 platforms/exynos5250-arndale.acpi/wdrt.asl delete mode 100644 platforms/foundation-v8.acpi/dbgp.asl delete mode 100644 platforms/foundation-v8.acpi/dmar.asl delete mode 100644 platforms/foundation-v8.acpi/hpet.asl delete mode 100644 platforms/foundation-v8.acpi/ivrs.asl delete mode 100644 platforms/foundation-v8.acpi/s3pt.asl delete mode 100644 platforms/foundation-v8.acpi/sbst.asl delete mode 100644 platforms/foundation-v8.acpi/slic.asl delete mode 100644 platforms/foundation-v8.acpi/spcr.asl delete mode 100644 platforms/foundation-v8.acpi/tcpa.asl delete mode 100644 platforms/foundation-v8.acpi/tpm2.asl delete mode 100644 platforms/foundation-v8.acpi/waet.asl delete mode 100644 platforms/foundation-v8.acpi/wdat.asl delete mode 100644 platforms/foundation-v8.acpi/wddt.asl delete mode 100644 platforms/foundation-v8.acpi/wdrt.asl -- 1.8.3.1

[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 00/13 v2] 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. 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.
