5d40a857 - mlxbf-bootctl: Support sysfs entries for RTC battery status

Fri, 24 Jan 2025 14:46:55 +0000

mlxbf-bootctl: Support sysfs entries for RTC battery statusThis patch extends the mlxbf-bootctl driver's sysfs entriesto support read access for the board's RTC battery status.A successful read from this attribute returns the status ofthe board's RTC battery. The RTC battery status register isalso cleared upon successful read operation.Signed-off-by: Xiangrong Li Reviewed-by: David Thompson Reviewed-by: Ilpo Järvinen Link: https://lore.kernel.org/r/20250124144655.48564-1-xiangrongl@nvidia.comSigned-off-by: Ilpo Järvinen List of files: /linux-6.15/Documentation/ABI/testing/sysfs-platform-mellanox-bootctl

7e38a742 - mlxbf-bootctl: Support sysfs entries for MFG fields

Mon, 21 Aug 2023 18:39:39 +0000

mlxbf-bootctl: Support sysfs entries for MFG fieldsThis patch extends the mlxbf-bootctl driver's sysfs entriesto support read and write access for the manufacturing (MFG)fields in the board-level EEPROM. The MFG fields are setonce during the board manufacturing phase, and then the MFGfields are write-protected.Signed-off-by: David Thompson Reviewed-by: Shravan Kumar Ramani Link: https://lore.kernel.org/r/20230821183939.3229-1-davthompson@nvidia.comSigned-off-by: Hans de Goede List of files: /linux-6.15/Documentation/ABI/testing/sysfs-platform-mellanox-bootctl

e9d1b2d0 - mlxbf-bootctl: Add sysfs file for BlueField boot log

Thu, 11 May 2023 14:49:24 +0000

mlxbf-bootctl: Add sysfs file for BlueField boot logThis commit adds sysfs interface to be used to write into theboot log which is 1KB HW buffer on BlueField SoC. The same logbuffer is also used by firmware code like ATF/UEFI, and can bedisplayed by userspace tools or from external host via USB/PCIe.Signed-off-by: Liming Sun Reviewed-by: Vadim Pasternak Link: https://lore.kernel.org/r/20230511144924.171585-1-limings@nvidia.comReviewed-by: Hans de Goede Signed-off-by: Hans de Goede List of files: /linux-6.15/Documentation/ABI/testing/sysfs-platform-mellanox-bootctl

82c3a0b7 - mlxbf-bootctl: Add sysfs file for BlueField boot fifo

Tue, 11 Apr 2023 15:39:42 +0000

mlxbf-bootctl: Add sysfs file for BlueField boot fifoThis commit adds sysfs file for BlueField boot fifo. The bootfifo is usually used to push boot stream via USB or PCIe. OnceOS is up, it can be reused by applications to read data orconfiguration from external host.Signed-off-by: Liming Sun Reviewed-by: David Thompson Link: https://lore.kernel.org/r/52b0b00dacbc4aad3169dd3667d79c85e334783b.1680657571.git.limings@nvidia.comReviewed-by: Hans de Goede Signed-off-by: Hans de Goede List of files: /linux-6.15/Documentation/ABI/testing/sysfs-platform-mellanox-bootctl

Wed, 18 Dec 2019 18:35:27 +0000

platform/mellanox: fix the mlx-bootctl sysfsThis is a follow-up commit for the sysfs attributes to changefrom DRIVER_ATTR to DEVICE_ATTR according to some initial comments.In such case, it's better to point the sysfs path to the deviceitself instead of the driver. The ABI document is also updated.Fixes: 79e29cb8fbc5 ("platform/mellanox: Add bootctl driver for Mellanox BlueField Soc")Signed-off-by: Liming Sun Signed-off-by: Andy Shevchenko List of files: /linux-6.15/Documentation/ABI/testing/sysfs-platform-mellanox-bootctl

79e29cb8 - platform/mellanox: Add bootctl driver for Mellanox BlueField Soc

Mon, 07 Oct 2019 15:48:46 +0000

platform/mellanox: Add bootctl driver for Mellanox BlueField SocThis commit adds the bootctl platform driver for Mellanox BlueFieldSoc, which queries secure state and controls the eMMC boot partitionswapping by sending SMC calls to ATF running at EL3.Below are the sequences of typical use case. 1. User requests boot partition swapping, which could be on-demand or during boot-image upgrade via UEFI capsule; 2. This bootctl driver handles the request and sends SMC call to ATF. ATF programs register BREADCRUMB0 which has value preserved during warm reset. It also programs eMMC to swap the boot partition; 3. After software reset (rebooting), ATF BL1 (BootRom) checks register BREADCRUMB0 and enable watchdog if configured; 4. If booting fails, the watchdog timer will trigger rebooting. In such case, ATF Boot ROM will switch the boot partition back to the previous one. This is a robust feature and used to prevent failure during boot partition upgrade.Reviewed-by: Vadim Pasternak Signed-off-by: Liming Sun Signed-off-by: Andy Shevchenko List of files: /linux-6.15/Documentation/ABI/testing/sysfs-platform-mellanox-bootctl
