From 9f0346dcbea363787186c94ef94dd01aaa215afa Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 5 Sep 2026 11:59:05 -0700 Subject: Merge tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core Pull driver core fixes from Danilo Krummrich: - Fix kernfs listxattr() not returning security xattr names (e.g. SELinux labels) when the kernfs node has no allocated kernfs_iattrs - Fix silent truncation of IRQ vector indices in the Rust PCI abstractions - Don't select OF from DRIVER_PE_KUNIT_TEST; skip the test when OF is disabled instead of silently enabling extra kernel functionality - Russ Weight is retiring from kernel development; update the Firmware Loader sysfs contact to the driver-core mailing list, add a CREDITS entry for Firmware Upload, and update MAINTAINERS accordingly * tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core: MAINTAINERS: Remove Russ Weight from Firmware Loader CREDITS: Add CREDITS entry for Firmware Upload firmware_loader: Change contact for sysfs nodes rust: pci: reject IRQ vector indices that do not fit in u32 kernfs: preserve security xattrs without allocating iattrs drivers: base: test: DRIVER_PE_KUNIT_TEST should not select OF --- drivers/crypto/ccp/dbc.h | 47 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 drivers/crypto/ccp/dbc.h (limited to 'drivers/crypto/ccp/dbc.h') diff --git a/drivers/crypto/ccp/dbc.h b/drivers/crypto/ccp/dbc.h new file mode 100644 index 000000000..e0fecbe92 --- /dev/null +++ b/drivers/crypto/ccp/dbc.h @@ -0,0 +1,47 @@ +/* SPDX-License-Identifier: GPL-2.0-only */ +/* + * AMD Platform Security Processor (PSP) Dynamic Boost Control support + * + * Copyright (C) 2023 Advanced Micro Devices, Inc. + * + * Author: Mario Limonciello + */ + +#ifndef __DBC_H__ +#define __DBC_H__ + +#include + +#include +#include +#include + +#include "psp-dev.h" + +struct psp_dbc_device { + struct device *dev; + struct psp_device *psp; + + union dbc_buffer *mbox; + + struct mutex ioctl_mutex; + + struct miscdevice char_dev; + + /* used to abstract communication path */ + bool use_ext; + u32 header_size; + u32 *payload_size; + u32 *result; + void *payload; +}; + +union dbc_buffer { + struct psp_request pa_req; + struct psp_ext_request ext_req; +}; + +void dbc_dev_destroy(struct psp_device *psp); +int dbc_dev_init(struct psp_device *psp); + +#endif /* __DBC_H */ -- cgit v1.3.1
