[PATCH v8 00/13] Introduce STM32 Firewall framework
by Gatien Chevallier 03 Feb '24

03 Feb '24

Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x platforms. STM32MP1x(ETZPC) and STM32MP2x(RIFSC) Firewall controllers register to the framework to offer firewall services such as access granting. This series of patches is a new approach on the previous STM32 system bus, history is available here: https://lore.kernel.org/lkml/20230127164040.1047583/ The need for such framework arises from the fact that there are now multiple hardware firewalls implemented across multiple products. Drivers are shared between different products, using the same code. When it comes to firewalls, the purpose mostly stays the same: Protect hardware resources. But the implementation differs, and there are multiple types of firewalls: peripheral, memory, ... Some hardware firewall controllers such as the RIFSC implemented on STM32MP2x platforms may require to take ownership of a resource before being able to use it, hence the requirement for firewall services to take/release the ownership of such resources. On the other hand, hardware firewall configurations are becoming more and more complex. These mecanisms prevent platform crashes or other firewall-related incoveniences by denying access to some resources. The stm32 firewall framework offers an API that is defined in firewall controllers drivers to best fit the specificity of each firewall. For every peripherals protected by either the ETZPC or the RIFSC, the firewall framework checks the firewall controlelr registers to see if the peripheral's access is granted to the Linux kernel. If not, the peripheral is configured as secure, the node is marked populated, so that the driver is not probed for that device. The firewall framework relies on the access-controller device tree binding. It is used by peripherals to reference a domain access controller. In this case a firewall controller. The bus uses the ID referenced by the access-controller property to know where to look in the firewall to get the security configuration for the peripheral. This allows a device tree description rather than a hardcoded peripheral table in the bus driver. The STM32 ETZPC device is responsible for filtering accesses based on security level, or co-processor isolation for any resource connected to it. The RIFSC is responsible for filtering accesses based on Compartment ID / security level / privilege level for any resource connected to it. STM32MP13/15/25 SoC device tree files are updated in this series to implement this mecanism. Changes in V8: - Add missing "simple-bus" compatible in STM32MP13/25 SoC device tree files for the ETZPC/RIFSC nodes - Add missing dependency on OF for OF_DYNAMIC that is selected by STM32_FIREWALL Changes in V7: - Separate indentation changes from access-controllers changes in the device tree file commits - Select OF_DYNAMIC when STM32_FIREWALL is set in order to use of_detach_node() in the firewall framework - Handle previously non-present RNG and HASH nodes in the STM32MP13 device tree file Changes in V6: - Rename access-controller to access-controllers - Remove access-controller-provider - Update device trees and other bindings accordingly - Rework ETZPC/RIFSC bindings to define what access-controllers cells contain inside #access-controller-cells - Some other minor fixes Changes in V5: - Integrate and rework the "feature-domains" binding patch in this patchset. The binding is renamed to "access-controller" - Rename every feature-domain* reference to access-control* ones - Correct loop bug and missing select STM32_FIREWALL in 32-bit platform Kconfig Changes in V4: - Fix typo in commit message and YAML check errors in "dt-bindings: Document common device controller bindings" Note: This patch should be ignored as stated in the cover letter. I've done this to avoid errors on this series of patch - Correct code syntax/style issues reported by Simon Horman - Added Jonathan's tag for IIO on the treewide patch Changes in V3: Change incorrect ordering for bindings commits leading to an error while running "make DT_CHECKER_FLAGS=-m dt_binding_check" Changes in V2: generic: - Add fw_devlink dependency for "feature-domains" property. bindings: - Corrected YAMLS errors highlighted by Rob's robot - Firewall controllers YAMLs no longer define the maxItems for the "feature-domains" property - Renamed st,stm32-rifsc.yaml to st,stm32mp25-rifsc.yaml - Fix examples in YAML files - Change feature-domains maxItems to 2 in firewall consumer files as there should not be more than 2 entries for now - Declare "feature-domain-names" as an optional property for firewall controllers child nodes. - Add missing "feature-domains" property declaration in bosch,m_can.yaml and st,stm32-cryp.yaml files firewall framework: - Support multiple entries for "feature-domains" property - Better handle the device-tree parsing using phandle+args APIs - Remove "resource firewall" type - Add a field for the name of the firewall entry - Fix licenses RIFSC: - Add controller name - Driver is now a module_platform_driver - Fix license ETZPC: - Add controller name - Driver is now a module_platform_driver - Fix license Device trees: - Fix rifsc node name - Move the "ranges" property under the "feature-domains" one Gatien Chevallier (12): dt-bindings: treewide: add access-controllers description dt-bindings: bus: document RIFSC dt-bindings: bus: document ETZPC firewall: introduce stm32_firewall framework of: property: fw_devlink: Add support for "access-controller" bus: rifsc: introduce RIFSC firewall controller driver arm64: dts: st: add RIFSC as an access controller for STM32MP25x boards bus: etzpc: introduce ETZPC firewall controller driver ARM: dts: stm32: add ETZPC as a system bus for STM32MP15x boards ARM: dts: stm32: put ETZPC as an access controller for STM32MP15x boards ARM: dts: stm32: add ETZPC as a system bus for STM32MP13x boards ARM: dts: stm32: put ETZPC as an access controller for STM32MP13x boards Oleksii Moisieiev (1): dt-bindings: document generic access controllers .../access-controllers.yaml | 84 + .../bindings/bus/st,stm32-etzpc.yaml | 87 + .../bindings/bus/st,stm32mp25-rifsc.yaml | 96 + .../bindings/crypto/st,stm32-cryp.yaml | 4 + .../bindings/crypto/st,stm32-hash.yaml | 4 + .../devicetree/bindings/dma/st,stm32-dma.yaml | 4 + .../bindings/dma/st,stm32-dmamux.yaml | 4 + .../devicetree/bindings/i2c/st,stm32-i2c.yaml | 4 + .../bindings/iio/adc/st,stm32-adc.yaml | 4 + .../bindings/iio/adc/st,stm32-dfsdm-adc.yaml | 4 + .../bindings/iio/dac/st,stm32-dac.yaml | 4 + .../bindings/media/cec/st,stm32-cec.yaml | 4 + .../bindings/media/st,stm32-dcmi.yaml | 4 + .../memory-controllers/st,stm32-fmc2-ebi.yaml | 4 + .../bindings/mfd/st,stm32-lptimer.yaml | 4 + .../bindings/mfd/st,stm32-timers.yaml | 4 + .../devicetree/bindings/mmc/arm,pl18x.yaml | 4 + .../bindings/net/can/bosch,m_can.yaml | 4 + .../devicetree/bindings/net/stm32-dwmac.yaml | 4 + .../bindings/phy/phy-stm32-usbphyc.yaml | 4 + .../bindings/regulator/st,stm32-vrefbuf.yaml | 4 + .../devicetree/bindings/rng/st,stm32-rng.yaml | 4 + .../bindings/serial/st,stm32-uart.yaml | 4 + .../bindings/sound/st,stm32-i2s.yaml | 4 + .../bindings/sound/st,stm32-sai.yaml | 4 + .../bindings/sound/st,stm32-spdifrx.yaml | 4 + .../bindings/spi/st,stm32-qspi.yaml | 4 + .../devicetree/bindings/spi/st,stm32-spi.yaml | 4 + .../devicetree/bindings/usb/dwc2.yaml | 4 + MAINTAINERS | 7 + arch/arm/boot/dts/st/stm32mp131.dtsi | 1063 ++++--- arch/arm/boot/dts/st/stm32mp133.dtsi | 51 +- arch/arm/boot/dts/st/stm32mp13xc.dtsi | 19 +- arch/arm/boot/dts/st/stm32mp13xf.dtsi | 19 +- arch/arm/boot/dts/st/stm32mp151.dtsi | 2756 +++++++++-------- arch/arm/boot/dts/st/stm32mp153.dtsi | 52 +- arch/arm/boot/dts/st/stm32mp15xc.dtsi | 19 +- arch/arm/mach-stm32/Kconfig | 1 + arch/arm64/Kconfig.platforms | 1 + arch/arm64/boot/dts/st/stm32mp251.dtsi | 7 +- drivers/bus/Kconfig | 10 + drivers/bus/Makefile | 1 + drivers/bus/stm32_etzpc.c | 141 + drivers/bus/stm32_firewall.c | 294 ++ drivers/bus/stm32_firewall.h | 83 + drivers/bus/stm32_rifsc.c | 252 ++ drivers/of/property.c | 2 + include/linux/bus/stm32_firewall_device.h | 141 + 48 files changed, 3352 insertions(+), 1938 deletions(-) create mode 100644 Documentation/devicetree/bindings/access-controllers/access-controllers.yaml create mode 100644 Documentation/devicetree/bindings/bus/st,stm32-etzpc.yaml create mode 100644 Documentation/devicetree/bindings/bus/st,stm32mp25-rifsc.yaml create mode 100644 drivers/bus/stm32_etzpc.c create mode 100644 drivers/bus/stm32_firewall.c create mode 100644 drivers/bus/stm32_firewall.h create mode 100644 drivers/bus/stm32_rifsc.c create mode 100644 include/linux/bus/stm32_firewall_device.h -- 2.25.1

[PATCH v11 00/15] Add audio support in v4l2 framework
by Shengjiu Wang 18 Jan '24

18 Jan '24

Audio signal processing also has the requirement for memory to memory similar as Video. This asrc memory to memory (memory ->asrc->memory) case is a non real time use case. User fills the input buffer to the asrc module, after conversion, then asrc sends back the output buffer to user. So it is not a traditional ALSA playback and capture case. It is a specific use case, there is no reference in current kernel. v4l2 memory to memory is the closed implementation, v4l2 current support video, image, radio, tuner, touch devices, so it is not complicated to add support for this specific audio case. Because we had implemented the "memory -> asrc ->i2s device-> codec" use case in ALSA. Now the "memory->asrc->memory" needs to reuse the code in asrc driver, so the first 3 patches is for refining the code to make it can be shared by the "memory->asrc->memory" driver. The main change is in the v4l2 side, A /dev/vl4-audioX will be created, user applications only use the ioctl of v4l2 framework. Other change is to add memory to memory support for two kinds of i.MX ASRC module. changes in v11 - add add-fixed-point-test-controls in vivid. - add v4l2_ctrl_fp_compose() helper function for min and max changes in v10 - remove FIXED_POINT type - change code base on media: v4l2-ctrls: add support for fraction_bits - fix issue reported by kernel test robot - remove module_alias changes in v9: - add MEDIA_ENT_F_PROC_AUDIO_RESAMPLER. - add MEDIA_INTF_T_V4L_AUDIO - add media controller support - refine the vim2m-audio to support 8k<->16k conversion. changes in v8: - refine V4L2_CAP_AUDIO_M2M to be 0x00000008 - update doc for FIXED_POINT - address comments for imx-asrc changes in v7: - add acked-by from Mark - separate commit for fixed point, m2m audio class, audio rate controls - use INTEGER_MENU for rate, FIXED_POINT for rate offset - remove used fmts - address other comments for Hans changes in v6: - use m2m_prepare/m2m_unprepare/m2m_start/m2m_stop to replace m2m_start_part_one/m2m_stop_part_one, m2m_start_part_two/m2m_stop_part_two. - change V4L2_CTRL_TYPE_ASRC_RATE to V4L2_CTRL_TYPE_FIXED_POINT - fix warning by kernel test rebot - remove some unused format V4L2_AUDIO_FMT_XX - Get SNDRV_PCM_FORMAT from V4L2_AUDIO_FMT in driver. - rename audm2m to viaudm2m. changes in v5: - remove V4L2_AUDIO_FMT_LPCM - define audio pixel format like V4L2_AUDIO_FMT_S8... - remove rate and format in struct v4l2_audio_format. - Add V4L2_CID_ASRC_SOURCE_RATE and V4L2_CID_ASRC_DEST_RATE controls -

[PATCHv3 RESEND 00/10] ASoC: fsl-asoc-card: compatibility integration of a generic codec use case for use with S/PDIF controller
by Elinor Montmasson 16 Jan '24

16 Jan '24

Hello, This is the v3 of the series of patch aiming to make the machine driver "fsl-asoc-card" compatible with use cases where there is no real codec driver. It proposes to use the "spdif_receiver" and "spdif_transmitter" drivers instead of the dummy codec. This is a first step in using the S/PDIF controller with the ASRC. The five first patches add compatibility with the pair of codecs "spdif_receiver" and "spdif_transmitter" with a new compatible, "fsl,imx-audio-generic". Codec parameters are set with default values. Consequently, the driver is modified to work with multi-codec use cases. It can get 2 codecs phandles from the device tree, and the "fsl_asoc_card_priv" struct now has 2 "codec_priv" to store properties of both codecs. It is fixed to 2 codecs as only "fsl,imx-audio-generic" uses multiple codecs at the moment. However, the driver now uses for_each_codecs macros when possible to ease future implementations of multi-codec configurations. The remaining patches add configuration options for the device tree. They configure the CPU DAI when using "fsl,imx-audio-generic". These options are usually hard-coded in "fsl-asoc-card.c" for each audio codec. Because the generic codec could be used with other CPU DAIs than the S/PDIF controller, setting these parameters could be required. This series of patch was successfully built for arm64 and x86 on top of the latest for-next branch of the ASoC git tree on the 14th of December. These modifications have also been tested on an i.MX8MN evaluation board, with a linux kernel RT v6.1.26-rt8. We also have a few questions, following remarks made by Krzysztof Kozlowski in a previous email for patch 10/10: > >>> The compatible list for this generic sound card currently: > >>> @@ -48,6 +51,8 @@ The compatible list for this generic sound card > >>> currently: > >>> > >>> "fsl,imx-audio-nau8822" > >>> > >>> + "fsl,imx-audio-generic" > >> > >> Generic does not look like hardware specific. > > > > Even if our end goal is to use it with the S/PDIF controller, this new > > support can be used with different hardware that doesn't > > require a codec.

[RESEND PATCH 0/1] ALSA: virtio: add support for audio controls
by Aiswarya Cyriac 15 Jan '24

15 Jan '24

From: Anton Yakovlev <anton.yakovlev(a)opensynergy.com> Implementation of support for audio controls in accordance with the extension of the virtio sound device specification[1] planned for virtio-v1.3-cs01. Design　of virtual audio controls is based on and derived from ALSA audio controls. It allows the driver to perform all standard operations, such as reading and writing audio control value, as well as working with metadata (represented in the TLV form). The driver part was tested on top of the Linux 5.10 kernel. As a device part was used OpenSynergy proprietary implementation.
