- i2c-hid support for wakeup from suspend-to-idle
2020-10-15HID: i2c-hid: Enable wakeup capability from Suspend-to-IdleKai-Heng Feng1-0/+12
Many laptops can be woken up from Suspend-to-Idle by touchpad. This is also the default behavior on other OSes. However, if touchpad and touchscreen contact to each other when lid is closed, wakeup events can be triggered inadventertly. So let's disable the wakeup by default, but enable the wakeup capability so users can enable it at their own discretion.

2020-10-15tracing: support "bool" type in synthetic trace eventsAxel Rasmussen1-0/+4
It's common [1] to define tracepoint fields as "bool" when they contain a true / false value. Currently, defining a synthetic event with a "bool" field yields EINVAL. It's possible to work around this by using e.g. u8 (assuming sizeof(bool) is 1, and bool is unsigned; if either of these properties don't match, you get EINVAL [2]). Supporting "bool" explicitly makes hooking this up easier and more portable for userspace.

2020-10-15tracing: Handle synthetic event array field type checking correctlyTom Zanussi1-3/+9
Since synthetic event array types are derived from the field name, there may be a semicolon at the end of the type which should be stripped off. If there are more characters following that, normal type string checking will result in an invalid type. Without this patch, you can end up with an invalid field type string that gets displayed in both the synthetic event description and the event format: Before: # echo 'myevent char str[16]; int v' >> synthetic_events # cat synthetic_events myevent char[16]; str; int v name: myevent ID: 1936 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:char str[16];; offset:8; size:16; signed:1; field:int v; offset:40; size:4; signed:1; print fmt: "str=%s, v=%d", REC->str, REC->v After: # echo 'myevent char str[16]; int v' >> synthetic_events # cat synthetic_events myevent char[16] str; int v # cat events/synthetic/myevent/format name: myevent ID: 1936 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:char str[16]; offset:8; size:16; signed:1; field:int v; offset:40; size:4; signed:1; print fmt: "str=%s, v=%d", REC->str, REC->v Link: https://lkml.kernel.org/r/6587663b56c2d45ab9d8c8472a2110713cdec97d.1602598160.git.zanussi@kernel.org [ <rostedt@goodmis.org>: wrote parse_synth_field() snippet. ] Fixes: 4b147936fa50 (tracing: Add support for 'synthetic' events) Reported-by: Masami Hiramatsu <mhiramat@kernel.org> Tested-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Tom Zanussi <zanussi@kernel.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
2020-10-15selftests/ftrace: Change synthetic event name for inter-event-combined testTom Zanussi1-4/+4
This test uses waking+wakeup_latency as an event name, which doesn't make sense since it includes an operator. Illegal names are now detected by the synthetic event command parsing, which causes this test to fail. Change the name to 'waking_plus_wakeup_latency' to prevent this.

2020-10-15tracing: Don't show dynamic string internals in synthetic event descriptionTom Zanussi1-1/+9
For synthetic event dynamic fields, the type contains "__data_loc", which is basically an internal part of the type which is only meant to be displayed in the format, not in the event description itself, which is confusing to users since they can't use __data_loc on the command-line to define an event field, which printing it would lead them to believe. So filter it out from the description, while leaving it in the type.

2020-10-15parisc/sticon: Add user font supportHelge Deller4-268/+326
This is a major rework of the sticon (parisc text console) driver in order to support user font support. Usually one want to use the stifb (parisc framebuffer driver) which is based on fbcon and does support fonts and colors, but some old machines (e.g. HP 730 workstations) don't provide a supported stifb graphic card, and for those user fonts are preferred. This patch drops unused code for software cursor and scrollback, enhances the debug output and adds better documentation.
