[PATCH] i2c: mxc_i2c: Use hex notation for the base address
by Fabio Estevam 13 Feb '23

13 Feb '23

Printing the I2C controller base address in decimal notation is not helpful. Change it to hex notation, which is the standard format found in the Reference Manual and devicetree.

[PATCH v2] riscv: cancel the limitation that NR_CPUS is less than or equal to 32
by Xiang W 13 Feb '23

13 Feb '23

Various specifications of riscv allow the number of hart to be greater than 32. The limit of 32 is determined by gd->arch.available_harts. We can eliminate this limitation through bitmaps. Currently, the number of hart is limited to 4095, and 4095 is the limit of the RISC-V Advanced Core Local Interruptor Specification. Test on sifive unmatched.

[PATCH 00/24] trace: Update the trace feature to work with trace-cmd
by Simon Glass 12 Feb '23

12 Feb '23

Since U-Boot's tracing feature was originally written, quite a few changes have taken place in this domain. The original text format used by tracing is still emitted by Linux, but a new trace-cmd tool has invented a binary format which is now used by new tools, such as kernelshark. With recent distributions and the move to Python 3, the old pybootchart tool does not build or run. Unfortunately there is no 1:1 replacement for the features that were provided by pybootchart, or at least it is not obvious. Still, it makes sense to keep with the times. This series updates proftool to use the new binary format, adding support for function and funcgraph tracing, so that U-Boot's trace records can be examined by trace-cmd and kernelshark. This series also adds support for a flamegraph, which provides a visual way to see which functions are called a lot, as well as which ones consume the most time. Some minor updates to the trace implementation within U-Boot are included, to provide a little more information and to fix a few problems. No unit tests are provided by proftool, but a functional test ensures that sandbox can emit traces which can be processed by proftool, then parsed by trace-cmd and that the timing of the various formats looks consistent. Simon Glass (24): .gitignore: Ignore the moveconfig database sandbox: Expand the space for sandbox_vpl sandbox: Bring back setting mon_len in global_data dm: Allow serial output during the relocation process timer: Tidy up use of notrace time: Tidy up some unnecessary #ifdefs trace: Reduce the default for TRACE_EARLY_CALL_DEPTH_LIMIT abuf: Support use from tools trace: Update the file header trace: Reduce the number of function sites trace: Track the minimum stack depth trace: Show a few more stats about tracing trace: Correct the relocation handover with buffer overflow trace: Detect an infinite loop trace: Rename prof to trace and improve comments trace: Update proftool to use new binary format trace: Drop use of objsection trace: Use text_base from the trace header trace: Support output of funcgraph records trace: Support output of a flamegraph trace: Provide a flamegraph that uses timing Docker: Support trace-cmd trace: Add a test trace: Update documentation .azure-pipelines.yml | 8 + .gitattributes | 1 + .gitignore | 3 + .gitlab-ci.yml | 12 + arch/sandbox/dts/sandbox_vpl.dtsi | 4 +- common/board_f.c | 3 + common/board_r.c | 9 + doc/develop/pics/flamegraph.png | Bin 0 -> 48224 bytes doc/develop/pics/flamegraph_timing.png | Bin 0 -> 31305 bytes doc/develop/pics/flamegraph_zoom.png | Bin 0 -> 25465 bytes doc/develop/pics/kernelshark.png | Bin 0 -> 29617 bytes doc/develop/pics/kernelshark_fg.png | Bin 0 -> 28899 bytes doc/develop/trace.rst | 281 ++++- doc/usage/cmd/trace.rst | 163 +++ doc/usage/index.rst | 1 + drivers/core/device.c | 3 +- drivers/timer/timer-uclass.c | 2 +- include/timer.h | 13 +- include/trace.h | 18 +- lib/Kconfig | 2 +- lib/abuf.c | 21 +- lib/time.c | 14 +- lib/trace.c | 93 +- test/py/tests/test_trace.py | 304 +++++ tools/Makefile | 3 + tools/docker/Dockerfile | 16 + tools/proftool.c | 1598 ++++++++++++++++++++++-- 27 files changed, 2345 insertions(+), 227 deletions(-) create mode 100644 doc/develop/pics/flamegraph.png create mode 100644 doc/develop/pics/flamegraph_timing.png create mode 100644 doc/develop/pics/flamegraph_zoom.png create mode 100644 doc/develop/pics/kernelshark.png create mode 100644 doc/develop/pics/kernelshark_fg.png create mode 100644 doc/usage/cmd/trace.rst create mode 100644 test/py/tests/test_trace.py -- 2.39.0.314.g84b9a713c41-goog

[PATCH 0/3] Fix boot regressions on at least TI am62x
by Sjoerd Simons 08 Feb '23

08 Feb '23

When booting a recent u-boot master on TI am62x with the distro boot sequence it fails loading the FDT: Booting using the fdt blob at 0x88000000 Working FDT set to 88000000 Loading Ramdisk to 8d711000, end 8ffffd95 ... OK ERROR: reserving fdt memory region failed (addr=9e780000 size=80000 flags=4) ERROR: reserving fdt memory region failed (addr=9e800000 size=1800000 flags=4) ERROR: reserving fdt memory region failed (addr=9db00000 size=c00000 flags=4) ERROR: Failed to allocate 0x8f58 bytes below 0x90000000. device tree - allocation error FDT creation failed! resetting ... It turns out that this is caused by commit 06d514d77c37 ("lmb: consider EFI memory map") due to injecting both extra and some similar memory regions via a different path into the lmb. The following series fixes the apparent fallout from that ;) Sjoerd Simons (3): Bump LMB_MAX_REGIONS default to 16 lmb: Set correct lmb flags for EFI memory map entries lmb: Treat a region which is a subset as equal lib/Kconfig | 2 +- lib/lmb.c | 15 +++++++++------ 2 files changed, 10 insertions(+), 7 deletions(-) -- 2.39.0
