[PATCH v3 00/35] dm: Add programmatic generation of ACPI tables (part B)
by Simon Glass 07 Jul '20

07 Jul '20

This is split from the original series in an attempt to get things applied in chunks. This part includes: - writing basic ACPI code for integers, strings, names, packages - writing descriptors for GPIO, I2C, interrupts, SPI - writing code to enable/disable ACPI peripherals via GPIOs - writing SSDT and DSDT tables - additional ways to determine ACPI device names Much of this code is taken from coreboot and I have tried to avoid changing the original code for no reason. Changes include: - splitting the acpi_dp functions into their own file - adding tests - adding (lots of) comments - using a context pointer instead of global variables - tidying up some code where couldn't resist (e.g. acpigen_emit_namestring()) Changes in v3: - s/NUL/NULL/ for the NUL character, since that is in more common use - Fix 'an GPIO is found' typo - Update comment in acpi_device_set_i2c() to talk about scope parameter - Make acpi_device_write_spi() static - Add an extra comment about scope to acpi_device_set_spi() - Use BIT() in a few places - Resist the temptation to go to >80 characters - Add a reference to the ACPI spec - Add a define for the 0x80 constant - Move the function comments into this patch - Fix 'easy of testing' typo - Move two function comments into the previous patch - Allow the name parameter to be NULL - Add error checking to acpi_dp_add_integer_array() - Fix 'acpi_device.v' typo - Drop unused ACPI_CPU_STRING - Use an enum for the GPIO priority - Add error checking - Fix incorrect function names and arguments in commments - Add error checking for acpi_dp_add...() functions - Fix function name in comment for acpigen_write_not() - Use #defines for the mask values - Fix 'THe' typo - Rename MAX_ITEMS to MAX_ACPI_ITEMS - Make find_item() static and rename to find_acpi_item() - Rename build_type() and add a comment Drop coreboot_acpi_ids enum - Fix 'THe' typo - Rename build_type() to sort_acpi_item_type() - Refactor the code to remove the extra memcpy() - Recalculate the DSDT checksum only once - Add a comment as to why the checksum byte is set to 0 - Fix 'of' typo - Update acpi_dump_items() to take an enum - Update commit message and subject for clarity Changes in v2: - Update to add a new 'base' field to struct acpi_ctx - Free the memory allocated to the table and context - Fix memset of I2C descriptor - Fix memset of SPI descriptor Changes in v1: - Capitalise ACPI_OPS_PTR - Split into more patches for review - Add tests - Rebase on top of common.h series - Fix 'the an' typo - Move header definitions into this patch - Update sandbox driver slightly for testing - Switch parameter order of _acpi_fill_ssdt() and make it static - Fix 'sentinal' and 'METHOD_FILL_SDDT' typos - Correct the commit subject - Generalise the ACPI function recursion with acpi_recurse_method() - Generalise the ACPI function recursion with acpi_recurse_method() - Use OEM_TABLE_ID instead of ACPI_TABLE_CREATOR - Update ACPI_DSTATUS enum - Drop writing of coreboot tables - Generalise the ACPI function recursion with acpi_recurse_method() - Use acpi,ddn instead of acpi,desc - Rename to acpi_device_infer_name() - Update newly created sandbox tests Simon Glass (35): dm: core: Add an ACPI name for the root node acpi: Add a function to get a device path and scope acpi: Add a way to check device status irq: Add a method to convert an interrupt to ACPI acpi: Support generation of ACPI code acpi: Support generation of interrupt descriptor gpio: Add a method to convert a GPIO to ACPI acpi: Support string output acpi: Support generation of GPIO descriptor acpi: Support generation of a GPIO/irq for a device acpi: Support generation of I2C descriptor acpi: Support generation of SPI descriptor acpigen: Support writing a length acpigen: Support writing a package acpi: Support writing an integer acpi: Support writing a string acpi: Support writing a name acpi: Support writing a UUID acpi: Support writing Device Properties objects via _DSD acpi: Support writing a GPIO acpi: Support copying properties from device tree to ACPI acpi: Add support for various misc ACPI opcodes acpi: Add support for writing a Power Resource acpi: Add support for writing a GPIO power sequence acpi: Add support for a generic power sequence acpi: Add support for SSDT generation x86: acpi: Move MADT down a bit acpi: Record the items added to SSDT acpi: Support ordering SSDT data by device x86: Allow devices to write an SSDT acpi: Add support for DSDT generation x86: Allow devices to write to DSDT pci: Avoid a crash in device_is_on_pci_bus() dm: acpi: Enhance acpi_get_name() acpi: Add an acpi command to list/dump generated ACPI items arch/sandbox/dts/test.dts | 14 +- arch/x86/lib/acpi_table.c | 55 +- cmd/acpi.c | 15 +- doc/device-tree-bindings/chosen.txt | 9 + doc/device-tree-bindings/device.txt | 13 + drivers/core/acpi.c | 220 ++++++- drivers/core/root.c | 13 + drivers/gpio/gpio-uclass.c | 21 + drivers/gpio/sandbox.c | 86 +++ drivers/i2c/sandbox_i2c.c | 1 + drivers/misc/irq-uclass.c | 18 +- drivers/misc/irq_sandbox.c | 16 + drivers/rtc/sandbox_rtc.c | 13 + drivers/spi/sandbox_spi.c | 1 + include/acpi/acpi_device.h | 401 +++++++++++++ include/acpi/acpi_dp.h | 287 +++++++++ include/acpi/acpigen.h | 355 ++++++++++++ include/asm-generic/gpio.h | 27 + include/dm/acpi.h | 71 +++ include/dm/device.h | 2 +- include/irq.h | 43 ++ include/spi.h | 4 +- include/test/ut.h | 17 + lib/acpi/Makefile | 3 + lib/acpi/acpi_device.c | 819 ++++++++++++++++++++++++++ lib/acpi/acpi_dp.c | 402 +++++++++++++ lib/acpi/acpi_table.c | 1 + lib/acpi/acpigen.c | 474 +++++++++++++++ test/dm/Makefile | 2 + test/dm/acpi.c | 277 ++++++++- test/dm/acpi_dp.c | 512 ++++++++++++++++ test/dm/acpigen.c | 865 ++++++++++++++++++++++++++++ test/dm/gpio.c | 62 ++ test/dm/irq.c | 23 + test/dm/pci.c | 14 + 35 files changed, 5123 insertions(+), 33 deletions(-) create mode 100644 include/acpi/acpi_device.h create mode 100644 include/acpi/acpi_dp.h create mode 100644 include/acpi/acpigen.h create mode 100644 lib/acpi/acpi_device.c create mode 100644 lib/acpi/acpi_dp.c create mode 100644 lib/acpi/acpigen.c create mode 100644 test/dm/acpi_dp.c create mode 100644 test/dm/acpigen.c -- 2.27.0.290.gba653c62da-goog

[PATCH] test: Have test_fs work with non-functional guestmount tools
by Tom Rini 07 Jul '20

07 Jul '20

Since 2011 Ubuntu has intentionally broken support for guestmount[1] by default and requires sysadmin intervention to re-enable support. This in turn exposed that in our tests if guestmount is available but fails we do not fall back to trying to use sudo. Restructure our code to try sudo if guestmount fails rather than only when it is not in our path. Further, only note that we are using fuse on success of the call.

I'm not going to remove guestmount from the Docker containers as it's a useful reference for "what is required for a minimal environment for U-Boot builds" and perhaps we will switch to Debian instead at some point. --- test/py/tests/test_fs/conftest.py | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) diff --git a/test/py/tests/test_fs/conftest.py b/test/py/tests/test_fs/conftest.py index ee82169c2a37..d8ce1876ffca 100644 --- a/test/py/tests/test_fs/conftest.py +++ b/test/py/tests/test_fs/conftest.py @@ -206,10 +206,11 @@ def mount_fs(fs_type, device, mount_point): fuse_mounted = False try: if tool_is_in_path('guestmount'): - fuse_mounted = True check_call('guestmount -a %s -m /dev/sda %s' % (device, mount_point), shell=True) - else: + fuse_mounted = True + except CalledProcessError: + try: mount_opt = 'loop,rw' if re.match('fat', fs_type): mount_opt += ',umask=0000' @@ -219,8 +220,8 @@ def mount_fs(fs_type, device, mount_point): # may not be effective for some file systems check_call('sudo chmod a+rw %s' % mount_point, shell=True) - except CalledProcessError: - raise + except CalledProcessError: + raise def umount_fs(mount_point): """Unmount a volume. -- 2.17.1

[PATCH v2 1/2] cmd: env: use ENV_IS_IN_DEVICE in env info
by Patrick Delaunay 07 Jul '20

07 Jul '20

Use the define ENV_IS_IN_DEVICE to test if one the CONFIG_ENV_IS_IN_... is defined and correct the detection of persistent storage support in the command "env info" if CONFIG_ENV_IS_NOWHERE is activated. Since commit 60d5ed2593c9 ("env: allow ENV_IS_NOWHERE with other storage target") test CONFIG_ENV_IS_NOWHERE is not enough; see also commit 953db29a1e9c6 ("env: enable saveenv command when one CONFIG_ENV_IS_IN is activated").

[PATCH v2] arm64: issue ISB after updating system registers
by Volodymyr Babchuk 07 Jul '20

07 Jul '20

ARM Architecture reference manual clearly states that PE pipeline should be flushed after any change to system registers. Refer to paragraph "B2.3.5 Memory Barriers" at page B2-92 of "Arm Architecture Reference Manual ARMv8 for ARMv8-A Architecture Profile" (ARM DDI 0487B.a). Failing to issue instruction memory synchronization barrier can lead to spurious errors, like synchronous exception when accessing FPU registers. This is very prominent on CPUs with long instruction pipeline, like ARM Cortex A72.

[PATCH] fs: fat: fix fat iteration
by Christian Gmeiner 07 Jul '20

07 Jul '20

According to the FAT specification it is valid to have files with an attribute value of 0x0. This fixes a regression where different U-Boot versions are showing different amount of files on the same storage device. With this change U-Boot shows the same number of files and folders as Linux and Windows.

[PATCH] common/board_f: Respect original FDT size while relocating
by Oleksandr Andrushchenko 07 Jul '20

07 Jul '20

From: Oleksandr Andrushchenko <oleksandr_andrushchenko(a)epam.com> While relocating FDT we reserve some memory for the new FDT and set the size of the FDT with that respect. But FDT may be placed at the end of the RAM leading to memory access beyond it. Fix this by copying exact FDT size bytes, not the reserved size.

[PATCH] Revert "ARM: dts: stm32: Reinstate card detect behavior on DHSOM"
by Patrick Delaunay 07 Jul '20

Since commit f13ff88b61c3 ("gpio: stm32: add ops set_dir_flags") the gpio flags are aupported by stm32 pinctrl driver. The cd-gpios is correctly handle in U-Boot and the patch on the device tree can be removed. This reverts commit 3c2e2a1a79608c5e046313a8c47586d9a734e2a3.

[PATCH 0/3] board: amlogic: add Odroid C4 support
by Neil Armstrong 07 Jul '20

07 Jul '20

This patchset adds support for the Hardkernel Odroid-C4 board based on an Amlogic S905X3 SoC (SM1). These patches were made very early from Christian Hewitt when the device was unveiled by Hardkernel, and superseed the patchset from Beniamino Galvani posted later. Beniamino, sorry for posting this over your patchset, but they are essentially the same and this one is already used by LibreELEC, Armbian and out KernelCI boards. It used the new Odroid-N2 board support instead of W400, and adds a doc file in RsT format.
