[for-linus][PATCH 2/2] ftrace: Fix function profilers filtering functionality

by Steven Rostedt

From: Kohei Enju <enjuk(a)amazon.com> Commit c132be2c4fcc ("function_graph: Have the instances use their own ftrace_ops for filtering"), function profiler (enabled via function_profile_enabled) has been showing statistics for all functions, ignoring set_ftrace_filter settings. While tracers are instantiated, the function profiler is not. Therefore, it should use the global set_ftrace_filter for consistency. This patch modifies the function profiler to use the global filter, fixing the filtering functionality. Before (filtering not working): ``` root@localhost:~# echo 'vfs*' > /sys/kernel/tracing/set_ftrace_filter root@localhost:~# echo 1 > /sys/kernel/tracing/function_profile_enabled root@localhost:~# sleep 1 root@localhost:~# echo 0 > /sys/kernel/tracing/function_profile_enabled root@localhost:~# head /sys/kernel/tracing/trace_stat/* Function Hit Time Avg s^2 -------- --- ---- --- --- schedule 314 22290594 us 70989.15 us 40372231 us x64_sys_call 1527 8762510 us 5738.382 us 3414354 us schedule_hrtimeout_range 176 8665356 us 49234.98 us 405618876 us __x64_sys_ppoll 324 5656635 us 17458.75 us 19203976 us do_sys_poll 324 5653747 us 17449.83 us 19214945 us schedule_timeout 67 5531396 us 82558.15 us 2136740827 us __x64_sys_pselect6 12 3029540 us 252461.7 us 63296940171 us do_pselect.constprop.0 12 3029532 us 252461.0 us 63296952931 us ``` After (filtering working): ``` root@localhost:~# echo 'vfs*' > /sys/kernel/tracing/set_ftrace_filter root@localhost:~# echo 1 > /sys/kernel/tracing/function_profile_enabled root@localhost:~# sleep 1 root@localhost:~# echo 0 > /sys/kernel/tracing/function_profile_enabled root@localhost:~# head /sys/kernel/tracing/trace_stat/* Function Hit Time Avg s^2 -------- --- ---- --- --- vfs_write 462 68476.43 us 148.217 us 25874.48 us vfs_read 641 9611.356 us 14.994 us 28868.07 us vfs_fstat 890 878.094 us 0.986 us 1.667 us vfs_fstatat 227 757.176 us 3.335 us 18.928 us vfs_statx 226 610.610 us 2.701 us 17.749 us vfs_getattr_nosec 1187 460.919 us 0.388 us 0.326 us vfs_statx_path 297 343.287 us 1.155 us 11.116 us vfs_rename 6 291.575 us 48.595 us 9889.236 us ``` Cc: stable(a)vger.kernel.org Link: https://lore.kernel.org/20250101190820.72534-1-enjuk@amazon.com Fixes: c132be2c4fcc ("function_graph: Have the instances use their own ftrace_ops for filtering") Signed-off-by: Kohei Enju <enjuk(a)amazon.com> Signed-off-by: Steven Rostedt (Google) <rostedt(a)goodmis.org> --- kernel/trace/ftrace.c | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) diff --git a/kernel/trace/ftrace.c b/kernel/trace/ftrace.c index 9b17efb1a87d..2e113f8b13a2 100644 --- a/kernel/trace/ftrace.c +++ b/kernel/trace/ftrace.c @@ -902,16 +902,13 @@ static void profile_graph_return(struct ftrace_graph_ret *trace, } static struct fgraph_ops fprofiler_ops = { - .ops = { - .flags = FTRACE_OPS_FL_INITIALIZED, - INIT_OPS_HASH(fprofiler_ops.ops) - }, .entryfunc = &profile_graph_entry, .retfunc = &profile_graph_return, }; static int register_ftrace_profiler(void) { + ftrace_ops_set_global_filter(&fprofiler_ops.ops); return register_ftrace_graph(&fprofiler_ops); } @@ -922,12 +919,11 @@ static void unregister_ftrace_profiler(void) #else static struct ftrace_ops ftrace_profile_ops __read_mostly = { .func = function_profile_call, - .flags = FTRACE_OPS_FL_INITIALIZED, - INIT_OPS_HASH(ftrace_profile_ops) }; static int register_ftrace_profiler(void) { + ftrace_ops_set_global_filter(&ftrace_profile_ops); return register_ftrace_function(&ftrace_profile_ops); } -- 2.45.2

[PATCH net 2/5] gve: guard XDP xmit NDO on existence of xdp queues

by Praveen Kaligineedi

From: Joshua Washington <joshwash(a)google.com> In GVE, dedicated XDP queues only exist when an XDP program is installed and the interface is up. As such, the NDO XDP XMIT callback should return early if either of these conditions are false. In the case of no loaded XDP program, priv->num_xdp_queues=0 which can cause a divide-by-zero error, and in the case of interface down, num_xdp_queues remains untouched to persist XDP queue count for the next interface up, but the TX pointer itself would be NULL. The XDP xmit callback also needs to synchronize with a device transitioning from open to close. This synchronization will happen via the GVE_PRIV_FLAGS_NAPI_ENABLED bit along with a synchronize_net() call, which waits for any RCU critical sections at call-time to complete.

[PATCH RFT 6/6] serial: sh-sci: Increment the runtime usage counter for the earlycon device

by Claudiu

From: Claudiu Beznea <claudiu.beznea.uj(a)bp.renesas.com> In the sh-sci driver, serial ports are mapped to the sci_ports[] array, with earlycon mapped at index zero. The uart_add_one_port() function eventually calls __device_attach(), which, in turn, calls pm_request_idle(). The identified code path is as follows: uart_add_one_port() -> serial_ctrl_register_port() -> serial_core_register_port() -> serial_core_port_device_add() -> serial_base_port_add() -> device_add() -> bus_probe_device() -> device_initial_probe() -> __device_attach() -> // ... if (dev->p->dead) { // ... } else if (dev->driver) { // ... } else { // ... pm_request_idle(dev); // ... } The earlycon device clocks are enabled by the bootloader. However, the pm_request_idle() call in __device_attach() disables the SCI port clocks while earlycon is still active. The earlycon write function, serial_console_write(), calls sci_poll_put_char() via serial_console_putchar(). If the SCI port clocks are disabled, writing to earlycon may sometimes cause the SR.TDFE bit to remain unset indefinitely, causing the while loop in sci_poll_put_char() to never exit. On single-core SoCs, this can result in the system being blocked during boot when this issue occurs. To resolve this, increment the runtime PM usage counter for the earlycon SCI device before registering the UART port.

[PATCH] iommu/tegra241-cmdqv: Read SMMU IDR1.CMDQS instead of hardcoding

by Nicolin Chen

The hardware limitation "max=19" actually comes from SMMU Command Queue. So, it'd be more natural for tegra241-cmdqv driver to read it out rather than hardcoding it itself. This is not an issue yet for a kernel on a baremetal system, but a guest kernel setting the queue base/size in form of IPA/gPA might result in a noncontiguous queue in the physical address space, if underlying physical pages backing up the guest RAM aren't contiguous entirely: e.g. 2MB-page backed guest RAM cannot guarantee a contiguous queue if it is 8MB (capped to VCMDQ_LOG2SIZE_MAX=19). This might lead to command errors when HW does linear-read from a noncontiguous queue memory. Adding this extra IDR1.CMDQS cap (in the guest kernel) allows VMM to set SMMU's IDR1.CMDQS=17 for the case mentioned above, so a guest-level queue will be capped to maximum 2MB, ensuring a contiguous queue memory.

[PATCH 6.6.y] f2fs: fix to wait dio completion

by Alva Lan

From: Chao Yu <chao(a)kernel.org> [ Upstream commit 96cfeb0389530ae32ade8a48ae3ae1ac3b6c009d ] It should wait all existing dio write IOs before block removal, otherwise, previous direct write IO may overwrite data in the block which may be reused by other inode.
