From 4352b8aee98005853aa63f57d6377282de17a33f Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 23 Aug 2026 13:28:57 -0700 Subject: Merge tag 'i3c/for-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/i3c/linux Pull I3C updates from Alexandre Belloni: "A new driver this cycle, for the AMD AXI I3C controller. There are also new features such as IBI wakeup support, SETAASA device discovery and ACPI support for the the DAA methods, meaning we can now communicate with the SPD devices on DDR5 modules. New driver: - AMD AXI I3C master controller Subsystem: - I3C Common Command Code (CCC) handling improvements, especially around GET CCCs - SETAASA device discovery support - ACPI support for all existing DAA methods like SETDASA, SETNEWDA as well as I2C devices on I3C bus - IBI-based wakeup support Drivers: - dw: SETAASA support - mipi-i3c-hci: advertise IBI wakeup capability, AMD_PT I3C controller support, PIO queue management support for HCI v1.2 - renesas: improve suspend to RAM support, add runtime PM support" * tag 'i3c/for-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/i3c/linux: (70 commits) i3c: dw: reduce do_daa time if there's no client i3c: mipi-i3c-hci: Add support for AMD_PT I3C controller i3c: mipi-i3c-hci: Add PIO queue management support for HCI v1.2 i3c: mipi-i3c-hci: Fix missing STAT_IBI_STATUS_THLD in PIO mode i3c: dw: rename "pclk" to "apb" to match dt-binding i3c: dw: make struct dw_i3c_cmd smaller i3c: dw: use COMMAND_PORT_TRANSFER_ARG instead of hardcoding i3c: renesas: Don't register devices when ENTDAA times out i3c: master: dw-i3c-master: fix OD timing for first broadcast i3c: mipi-i3c-hci: Advertise IBI wakeup capability i3c: mipi-i3c-hci: Factor out i3c_hci_sysdev() i3c: mipi-i3c-hci-pci: Propagate I3C wakeup requirements to PCI i3c: master: Reject IBI requests from non-IBI-capable devices i3c: master: Add helper to query bus wakeup requirements i3c: master: Report wakeup events for IBIs i3c: master: Support IBI-based wakeup capability i3c: master: Fix potential UAF in i3c_device_match() i3c: master: Fix potential UAF in i3c_device_uevent() i3c: Make dev->desc locking assumptions explicit i3c: master: Fix use-after-free of master->this ... --- tools/testing/radix-tree/test.h | 59 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 59 insertions(+) create mode 100644 tools/testing/radix-tree/test.h (limited to 'tools/testing/radix-tree/test.h') diff --git a/tools/testing/radix-tree/test.h b/tools/testing/radix-tree/test.h new file mode 100644 index 000000000..7ef7067e9 --- /dev/null +++ b/tools/testing/radix-tree/test.h @@ -0,0 +1,59 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#include +#include +#include +#include + +struct item { + struct rcu_head rcu_head; + unsigned long index; + unsigned int order; +}; + +struct item *item_create(unsigned long index, unsigned int order); +int item_insert(struct radix_tree_root *root, unsigned long index); +void item_sanity(struct item *item, unsigned long index); +void item_free(struct item *item, unsigned long index); +int item_delete(struct radix_tree_root *root, unsigned long index); +int item_delete_rcu(struct xarray *xa, unsigned long index); +struct item *item_lookup(struct radix_tree_root *root, unsigned long index); + +void item_check_present(struct radix_tree_root *root, unsigned long index); +void item_check_absent(struct radix_tree_root *root, unsigned long index); +void item_gang_check_present(struct radix_tree_root *root, + unsigned long start, unsigned long nr, + int chunk, int hop); +void item_full_scan(struct radix_tree_root *root, unsigned long start, + unsigned long nr, int chunk); +void item_kill_tree(struct radix_tree_root *root); + +int tag_tagged_items(struct xarray *, unsigned long start, unsigned long end, + unsigned batch, xa_mark_t iftag, xa_mark_t thentag); + +void xarray_tests(void); +void tag_check(void); +void multiorder_checks(void); +void iteration_test(unsigned order, unsigned duration); +void iteration_test2(unsigned duration); +void benchmark(void); +void idr_checks(void); +void ida_tests(void); + +struct item * +item_tag_set(struct radix_tree_root *root, unsigned long index, int tag); +struct item * +item_tag_clear(struct radix_tree_root *root, unsigned long index, int tag); +int item_tag_get(struct radix_tree_root *root, unsigned long index, int tag); +void tree_verify_min_height(struct radix_tree_root *root, int maxindex); +void verify_tag_consistency(struct radix_tree_root *root, unsigned int tag); + +extern int nr_allocated; + +/* Normally private parts of lib/radix-tree.c */ +struct radix_tree_node *entry_to_node(void *ptr); +void radix_tree_dump(struct radix_tree_root *root); +int root_tag_get(struct radix_tree_root *root, unsigned int tag); +unsigned long node_maxindex(struct radix_tree_node *); +unsigned long shift_maxindex(unsigned int shift); +int radix_tree_cpu_dead(unsigned int cpu); +extern struct radix_tree_preload radix_tree_preloads; -- cgit v1.3.1
