2024-02-22arm: ptdump: rename CONFIG_DEBUG_WX to CONFIG_ARM_DEBUG_WXChristophe Leroy
Patch series "mm: ptdump: Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute", v2. This series refactors CONFIG_DEBUG_WX for the 5 architectures implementing CONFIG_GENERIC_PTDUMP First rename stuff in ARM which uses similar names while not implementing CONFIG_GENERIC_PTDUMP. Then define a generic version of debug_checkwx() that calls ptdump_check_wx() when CONFIG_DEBUG_WX is set. Call it immediately after calling mark_rodata_ro() instead of calling it at the end of every mark_rodata_ro(). Then implement a debugfs attribute that can be used to trigger a W^X test at anytime and regardless of CONFIG_DEBUG_WX This patch (of 5): CONFIG_DEBUG_WX is a core option defined in mm/Kconfig.debug To avoid any future conflict, rename ARM version into CONFIG_ARM_DEBUG_WX.

2022-07-22ARM: defconfig: address renamed CONFIG_DEBUG_INFO=yArnd Bergmann
CONFIG_DEBUG_INFO is now implicitly selected if one picks one of the explicit options that could be DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT, DEBUG_INFO_DWARF4, DEBUG_INFO_DWARF5. This was actually not what I had in mind when I suggested making it a 'choice' statement, but it's too late to change again now, and the Kconfig logic is more sensible in the new form. Change any defconfig file that had CONFIG_DEBUG_INFO enabled but did not pick DWARF4 or DWARF5 explicitly to now pick the toolchain default.

2022-07-22ARM: refresh defconfig filesArnd Bergmann
A lot of Kconfig options have changed over the years, and we tend to not do a blind 'make defconfig' to refresh the files, to ensure we catch options that should not have gone away. I used some a bit of scripting to only rework the bits where an option moved around in any of the defconfig files, without also dropping any of the other lines, to make it clearer which options we no longer have.

2020-09-11ARM: config: aspeed: Fix selection of media driversJoel Stanley
In the 5.7 merge window the media kconfig was restructued. For most platforms these changes set CONFIG_MEDIA_SUPPORT_FILTER=y which keeps unwanted drivers disabled. The exception is if a config sets EMBEDDED or EXPERT (see b0cd4fb27665). In that case the filter is set to =n, causing a bunch of DVB tuner drivers (MEDIA_TUNER_*) to be accidentally enabled. This was noticed as it blew out the build time for the Aspeed defconfigs. Enabling the filter means the Aspeed config also needs to set CONFIG_MEDIA_PLATFORM_SUPPORT=y in order to have the CONFIG_VIDEO_ASPEED driver enabled.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull gpio updates from Linus Walleij: "This is the bulk of the GPIO changes for the v5.2 kernel cycle. A bit later than usual because I was ironing out my own mistakes. I'm holding some stuff back for the next kernel as a result, and this should be a healthy and well tested batch. Core changes: - The gpiolib MMIO driver has been enhanced to handle two direction registers, i.e. one register to set lines as input and one register to set lines as output. It turns out some silicon engineer thinks the ability to configure a line as input and output at the same time makes sense, this can be debated but includes a lot of analog electronics reasoning, and the registers are there and need to be handled consistently. Unsurprisingly, we enforce the lines to be either inputs or outputs in such schemes. - Send in the proper argument value to .set_config() dispatched to the pin control subsystem. Nobody used it before, now someone does, so fix it to work as expected. - The ACPI gpiolib portions can now handle pin bias setting (pull up or pull down). This has been in the ACPI spec for years and we finally have it properly integrated with Linux GPIOs. It was based on an observation from Andy Schevchenko that Thomas Petazzoni's changes to the core for biasing the PCA950x GPIO expander actually happen to fit hand-in-glove with what the ACPI core needed. Such nice synergies happen sometimes. New drivers: - A new driver for the Mellanox BlueField GPIO controller. This is using 64bit MMIO registers and can configure lines as inputs and outputs at the same time and after improving the MMIO library we handle it just fine. Interesting. - A new IXP4xx proper gpiochip driver with hierarchical interrupts should be coming in from the ARM SoC tree as well. Driver enhancements: - The PCA053x driver handles the CAT9554 GPIO expander. - The PCA053x driver handles the NXP PCAL6416 GPIO expander. - Wake-up support on PCA053x GPIO lines. - OMAP now does a nice asynchronous IRQ handling on wake-ups by letting everything wake up on edges, and this makes runtime PM work as expected too. Misc: - Several cleanups such as devres fixes. - Get rid of some languager comstructs that cause problems when compiling with LLVMs clang. - Documentation review and update" * tag 'gpio-v5.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (85 commits) gpio: Update documentation docs: gpio: convert docs to ReST and rename to *.rst gpio: sch: Remove write-only core_base gpio: pxa: Make two symbols static gpiolib: acpi: Respect pin bias setting gpiolib: acpi: Add acpi_gpio_update_gpiod_lookup_flags() helper gpiolib: acpi: Set pin value, based on bias, more accurately gpiolib: acpi: Change type of dflags gpiolib: Introduce GPIO_LOOKUP_FLAGS_DEFAULT gpiolib: Make use of enum gpio_lookup_flags consistent gpiolib: Indent entry values of enum gpio_lookup_flags gpio: pca953x: add support for pca6416 dt-bindings: gpio: pca953x: document the nxp,pca6416 gpio: pca953x: add pcal6416 to the of_device_id table gpio: gpio-omap: Remove conditional pm_runtime handling for GPIO interrupts gpio: gpio-omap: configure edge detection for level IRQs for idle wakeup tracing: stop making gpio tracing configurable gpio: pca953x: Configure wake-up path when wake-up is enabled gpio: of: Optimize quirk checks gpio: mmio: Drop bgpio_dir_inverted ...
2019-04-08tracing: stop making gpio tracing configurableUwe Kleine-König
gpio tracing was made configurable in 4.4-rc1 (commit ddd70280bf0e ("tracing: gpio: Add Kconfig option for enabling/disabling trace events")). Since then it is the only event type that can be compiled conditionally. Given that there is only little overhead I don't understand the reasoning and I was annoyed more than once that gpio events were not available without recompiling. So drop the Kconfig symbol and make gpio events available unconditionally. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2019-04-06block: remove CONFIG_LBDAFChristoph Hellwig
Currently support for 64-bit sector_t and blkcnt_t is optional on 32-bit architectures. These types are required to support block device and/or file sizes larger than 2 TiB, and have generally defaulted to on for a long time. Enabling the option only increases the i386 tinyconfig size by 145 bytes, and many data structures already always use 64-bit values for their in-core and on-disk data structures anyway, so there should not be a large change in dynamic memory usage either. Dropping this option removes a somewhat weird non-default config that has cause various bugs or compiler warnings when actually used.
