As stated in marvell-orion-mdio.txt deleted in commit 0781434a ("dt-bindings: net: orion-mdio: Convert to JSON schema") if 'interrupts' property is present, width of 'reg' should be 0x84. Otherwise, width of 'reg' should be 0x4. Fix 'examples:' and add constraints checking whether 'interrupts' property is present and validate it against fixed values in reg. Signed-off-by:

This property has always been supported by the Linux driver; see commit 9f93ac8d ("net-next: stmmac: Add dwmac-sun8i"). In fact, the original driver submission includes the phy-supply code but no mention of it in the binding, so the omission appears to be accidental. In addition, the property is documented in the binding for the previous hardware generation, allwinner,sun7i-a20-gmac. Document phy-supply in the binding to fix devicetree validation for the 25+ boards that already use this property.

The length of the questions prevents readers from locating content that's relevant at a glance. Convert to a more standard documentation format with sections and sub-sections rather than questions and answers.

This reverts commit 44ecda71. All versions of this patch on the mailing list, including the version that ended up getting merged, have portions of code guarded by the non-existent CONFIG_ARM64_WORKAROUND_2645198 option. Although Anshuman says he tested the code with some additional debug changes [1], I'm hesitant to fix the CONFIG option and light up a bunch of code right before I (and others) disappear for the end of year holidays, during which time we won't be around to deal with any fallout. So revert the change for now. We can bring back a fixed, tested version for a later -rc when folks are thinking about things other than trees and turkeys.

Add 'symstr' type for storing the kernel symbol as a string data instead of the symbol address. This allows us to filter the events by wildcard symbol name. e.g. # echo 'e:wqfunc workqueue.workqueue_execute_start symname=$function:symstr' >> dynamic_events # cat events/eprobes/wqfunc/format name: wqfunc ID: 2110 format: field:unsigned short common_type; offset:0; size:2; signed:0; field:unsigned char common_flags; offset:2; size:1; signed:0; field:unsigned char common_preempt_count; offset:3; size:1; signed:0; field:int common_pid; offset:4; size:4; signed:1; field:__data_loc char[] symname; offset:8; size:4; signed:1; print fmt: " symname=\"%s\"", __get_str(symname) Note that there is already 'symbol' type which just change the print format (so it still stores the symbol address in the tracing ring buffer.) On the other hand, 'symstr' type stores the actual "symbol+offset/size" data as a string. Link: https://lore.kernel.org/all/166679930847.1528100.4124308529180235965.stgit@devnote3/ Signed-off-by:

Default value of maxactive is set as num_possible_cpus() for nonpreemptable systems. For a 2-core system, only 2 kretprobe instances would be allocated in default, then these 2 instances for execve kretprobe are very likely to be used up with a pipelined command. Here's the testcase: a shell script was added to crontab, and the content of the script is: #!/bin/sh do_something_magic `tr -dc a-z < /dev/urandom | head -c 10` cron will trigger a series of program executions (4 times every hour). Then events loss would be noticed normally after 3-4 hours of testings. The issue is caused by a burst of series of execve requests. The best number of kretprobe instances could be different case by case, and should be user's duty to determine, but num_possible_cpus() as the default value is inadequate especially for systems with small number of cpus. This patch enables the logic for preemption as default, thus increases the minimum of maxactive to 10 for nonpreemptable systems.
