Quentin Monnet says:
====================
Hi, this set aims at updating the way bpftool versions are numbered.
Instead of copying the version from the kernel (given that the sources for
the kernel and bpftool are shipped together), align it on libbpf's version
number, with a fixed offset (6) to avoid going backwards. Please refer to
the description of the second commit for details on the motivations.
The patchset also adds the number of the version of libbpf that was used to
compile to the output of "bpftool version". Bpftool makes such a heavy
usage of libbpf that it makes sense to indicate what version was used to
build it.
v3:
- Compute bpftool's version at compile time, but from the macros exposed by
libbpf instead of calling a shell to compute $(BPFTOOL_VERSION) in the
Makefile.
- Drop the commit which would add a "libbpfversion" target to libbpf's
Makefile. This is no longer necessary.
- Use libbpf's major, minor versions with jsonw_printf() to avoid
offsetting the version string to skip the "v" prefix.
- Reword documentation change.
v2:
- Align on libbpf's version number instead of creating an independent
versioning scheme.
- Use libbpf_version_string() to retrieve and display libbpf's version.
- Re-order patches (1 <-> 2).

Since the notion of versions was introduced for bpftool, it has been
following the version number of the kernel (using the version number
corresponding to the tree in which bpftool's sources are located). The
rationale was that bpftool's features are loosely tied to BPF features
in the kernel, and that we could defer versioning to the kernel
repository itself.
But this versioning scheme is confusing today, because a bpftool binary
should be able to work with both older and newer kernels, even if some
of its recent features won't be available on older systems. Furthermore,
if bpftool is ported to other systems in the future, keeping a
Linux-based version number is not a good option.
Looking at other options, we could either have a totally independent
scheme for bpftool, or we could align it on libbpf's version number
(with an offset on the major version number, to avoid going backwards).
The latter comes with a few drawbacks:
- We may want bpftool releases in-between two libbpf versions. We can
always append pre-release numbers to distinguish versions, although
those won't look as "official" as something with a proper release
number. But at the same time, having bpftool with version numbers that
look "official" hasn't really been an issue so far.
- If no new feature lands in bpftool for some time, we may move from
e.g. 6.7.0 to 6.8.0 when libbpf levels up and have two different
versions which are in fact the same.
- Following libbpf's versioning scheme sounds better than kernel's, but
ultimately it doesn't make too much sense either, because even though
bpftool uses the lib a lot, its behaviour is not that much conditioned
by the internal evolution of the library (or by new APIs that it may
not use).
Having an independent versioning scheme solves the above, but at the
cost of heavier maintenance. Developers will likely forget to increase
the numbers when adding features or bug fixes, and we would take the
risk of having to send occasional "catch-up" patches just to update the
version number.
Based on these considerations, this patch aligns bpftool's version
number on libbpf's. This is not a perfect solution, but 1) it's
certainly an improvement over the current scheme, 2) the issues raised
above are all minor at the moment, and 3) we can still move to an
independent scheme in the future if we realise we need it.
Given that libbpf is currently at version 0.7.0, and bpftool, before
this patch, was at 5.16, we use an offset of 6 for the major version,
bumping bpftool to 6.7.0. Libbpf does not export its patch number;
leave bpftool's patch number at 0 for now.
It remains possible to manually override the version number by setting
BPFTOOL_VERSION when calling make.

Minimal support for interacting with dynamic events, trace_event and
ftrace. Core outline of flow between user process, ioctl and trace_event
APIs.
User mode processes that wish to use trace events to get data into
ftrace, perf, eBPF, etc are limited to uprobes today. The user events
features enables an ABI for user mode processes to create and write to
trace events that are isolated from kernel level trace events. This
enables a faster path for tracing from user mode data as well as opens
managed code to participate in trace events, where stub locations are
dynamic.
User processes often want to trace only when it's useful. To enable this
a set of pages are mapped into the user process space that indicate the
current state of the user events that have been registered. User
processes can check if their event is hooked to a trace/probe, and if it
is, emit the event data out via the write() syscall.
Two new files are introduced into tracefs to accomplish this:
user_events_status - This file is mmap'd into participating user mode
processes to indicate event status.
user_events_data - This file is opened and register/delete ioctl's are
issued to create/open/delete trace events that can be used for tracing.
The typical scenario is on process start to mmap user_events_status. Processes
then register the events they plan to use via the REG ioctl. The ioctl reads
and updates the passed in user_reg struct. The status_index of the struct is
used to know the byte in the status page to check for that event. The
write_index of the struct is used to describe that event when writing out to
the fd that was used for the ioctl call. The data must always include this
index first when writing out data for an event. Data can be written either by
write() or by writev().
For example, in memory:
int index;
char data[];
Psuedo code example of typical usage:
struct user_reg reg;
int page_fd = open("user_events_status", O_RDWR);
char *page_data = mmap(NULL, PAGE_SIZE, PROT_READ, MAP_SHARED, page_fd, 0);
close(page_fd);
int data_fd = open("user_events_data", O_RDWR);
reg.size = sizeof(reg);
reg.name_args = (__u64)"test";
ioctl(data_fd, DIAG_IOCSREG, ®);
int status_id = reg.status_index;
int write_id = reg.write_index;
struct iovec io[2];
io[0].iov_base = &write_id;
io[0].iov_len = sizeof(write_id);
io[1].iov_base = payload;
io[1].iov_len = sizeof(payload);
if (page_data[status_id])
writev(data_fd, io, 2);
User events are also exposed via the dynamic_events tracefs file for
both create and delete. Current status is exposed via the user_events_status
tracefs file.
Simple example to register a user event via dynamic_events:
echo u:test >> dynamic_events
cat dynamic_events
u:test
If an event is hooked to a probe, the probe hooked shows up:
echo 1 > events/user_events/test/enable
cat user_events_status
1:test # Used by ftrace
Active: 1
Busy: 1
Max: 4096
If an event is not hooked to a probe, no probe status shows up:
echo 0 > events/user_events/test/enable
cat user_events_status
1:test
Active: 1
Busy: 0
Max: 4096
Users can describe the trace event format via the following format:
name[:FLAG1[,FLAG2...] [field1[;field2...]]
Each field has the following format:
type name
Example for char array with a size of 20 named msg:
echo 'u:detailed char[20] msg' >> dynamic_events
cat dynamic_events
u:detailed char[20] msg
Data offsets are based on the data written out via write() and will be
updated to reflect the correct offset in the trace_event fields. For dynamic
data it is recommended to use the new __rel_loc data type. This type will be
the same as __data_loc, but the offset is relative to this entry. This allows
user_events to not worry about what common fields are being inserted before
the data.
The above format is valid for both the ioctl and the dynamic_events file.

boards. Note that these GPIO's are typically 'configured' in Boot
Firmware via gpio-hog therefore we only configure line names to keep the
boot firmware configuration from changing on kernel init.

Since commit 9a0f3b157e22 ("arm64: dts: imx8mn: Enable GPU")
imx8mn-venice-gw7902 will hang during kernel init because it uses
a MIMX8MN5CVTI which does not have a GPU.
Disable pgc_gpumix to work around this. We also disable the GPU devices
that depend on the gpumix power domain and pgc_gpu to avoid them staying
in a probe deferred state forever.

Like usb3_phy0 the default state of the usb3_phy1 should be disabled, so
it is only enabled on boards exposing this USB port.

The driver differs from clocks point of view, so the i.MX8QXP
is not backwards compatible with i.MX7ULP.

The slew rate and drive-strength of the i2c3 pads were much too
high. Bring them down to avoid signal quality issues.

This adds support for the internal display of the Reform2 Laptop, which
is connected to the i.MX8MQ via a MIPI-DSI->eDP bridge chip. Clocking
is derived from a system PLL, which provides quite good rate matching
for the single supported display mode and keeps the video PLL free for
usage with the external display, which isn't supported yet.
