Is there a quick way to work around this?
My goal is start compile chromium. I really don't care about this installation. After I solve this problem I will drop the entire docker container. |

pingtoo,
You appear to have a systemd install and its trying to pull in sys-apps/systemd-utils which is for non systemd users only.
Or you have selected a systemd profile on on openRC install, so systemd will be in the part of package list you are not sharing.

NeddySeagoon,
Again, please ignore my post. I got it going by doing | Code: | | emerge -C virtual/udev virtual/tmpfiles |
No the build in in progress, hopfully we will able to reproduce the error. |

I am using Pi 4B.
This build environment is a docker container from Gentoo official stage3 and portage.
I am using your binhost, which pulling 224 binaries for total of 228 packages. saved a lots of time thanks to your binhost. |

Quick update,
The emerge process finish failed. Two packages not complete, x11-libs/gtk+ and www-client/chromium. I think they are related, chromium build log indicate something missing for pkg_config("atk") and gtk+ failed in postinst phase.
Will investigate more. |

After reviewing the source code I think this is a design bug in chromium. It is forcing using dotProd ARM extension without further check if CPU arch actually support this extension or not. This can be found in the | https://github.com/chromium/chromium/blob/main/third_party/libaom/BUILD.gn#L224: | if (current_cpu == "arm64") {
source_set("libaom_intrinsics_arm_crc32") {
check_includes = false
configs -= [ "//build/config/compiler:chromium_code" ]
configs += [ "//build/config/compiler:no_chromium_code" ]
configs += [ ":libaom_config" ]
if (!is_win || is_clang) {
cflags = [ "-march=armv8-a+crc" ]
}
sources = aom_av1_encoder_intrin_arm_crc32
}
source_set("libaom_intrinsics_neon_dotprod") {
check_includes = false
configs -= [ "//build/config/compiler:chromium_code" ]
configs += [ "//build/config/compiler:no_chromium_code" ]
configs += [ ":libaom_config" ]
if (!is_win || is_clang) {
cflags = [ "-march=armv8.2-a+dotprod" ]
}
sources = aom_av1_common_intrin_neon_dotprod
sources += aom_dsp_common_intrin_neon_dotprod
sources += aom_av1_encoder_intrin_neon_dotprod
sources += aom_dsp_encoder_intrin_neon_dotprod
}
source_set("libaom_intrinsics_neon_i8mm") {
check_includes = false
configs -= [ "//build/config/compiler:chromium_code" ]
configs += [ "//build/config/compiler:no_chromium_code" ]
configs += [ ":libaom_config" ]
if (!is_win || is_clang) {
cflags = [ "-march=armv8.2-a+dotprod+i8mm" ]
}
sources = aom_av1_common_intrin_neon_i8mm
sources += aom_dsp_common_intrin_neon_i8mm
}
} |
So the compiler error may be able to work around by define (or undefine) the CFLAGS remove the "-march=XXX". This way the build system defined "-march-armv8.2+dotprod" will take place and everything will be included in the object code. However it is not clear for me if the executable will work on RPI4. Because the actual CPU does not include support for dotprod extension instruction. So likely when viewing stream encode in AV1 format will likely cause a wrong instruction fault.
The above is accrue in 117 however in 118 There some changes, so the same compiler error "dot_prod_permute_tbl undeclared" unlikely will happen. But the chromium build system remain the same so same conclusion that when viewing stream encode in AV1 format will likely case a wrong instruction fault.
However in 117, you have option to use flag system-av1, So you may be able to work around this problem. In 118 this option seems to be gone. |

I have the same problem here. Compiling with both GCC and Clang gives me dot_prod_permute_tbl related errors. |

Eewww. The X-Gene 1 is bare armv8-a. It does not hove any of the optional extensions at all. That was the first ever aarch64 CPU.
A few devs have them in the form of Mudan server boards.
My Pi4 router reports
| Code: | processor : 0
BogoMIPS : 108.00
Features : fp asimd evtstrm crc32 cpuid
CPU implementer : 0x41
CPU architecture: 8
CPU variant : 0x0
CPU part : 0xd08
CPU revision : 3 |
and my Hawk (X-Gene 3 / Ampere 8130) says | Code: | processor : 0
BogoMIPS : 80.00
Features : fp asimd evtstrm aes pmull sha1 sha2 crc32 cpuid
CPU implementer : 0x50
CPU architecture: 8
CPU variant : 0x3
CPU part : 0x000
CPU revision : 2 |
I don,t see +dotprod in either but Chromium builds in a KVM on the build system.
I can't try running Chromium on the Hawk. It's very noisy so it's confined to the garage. I can't really fit a GPU ether. The poor wee AST2500 BMC isn't up to it.
I do have Chromium built though.
My Pi4 test bed was robbed for bits to fix the Router, so needs to be reinstalled before I can try to run Chromium.
For the build to fail for | Code: | | cflags = [ "-march=armv8.2-a+dotprod" ] |
the build system would need to both build and execute instructions that the Pi4 does not have.
That would trigger Illegal Instruction exceptions in dmesg.
It's quite possible for a compiler to emit instructions that the build host cannot execute.

NeddySeagoon,
Thanks for the confirmation.
I think in 117 if you build with system-av1 use flag the result binary will have better change to work. Because the libaom is configured correctly for NEON (asimd)
I think gcc with -march=armv8.2-a+dotprod will emitting Intrinsic function when source code contain those call. Those intrinsic function exist in libaom and is enabled by the setting, what I don't understand yet is how the system choose the path to enable it. it looks to me is cmake some where ran a cpu detection function and decide that logic but I have not able to find such function.
for clang according to the comment it need to be at v16 to have the dotprod intrinsic function to emit in the aom code. |

I am going to give it a go again. Just want to run until compile fail than examine more detail.
Previously I was not able to start compile due to gtk install failure.
I think gtk install failed because I am running inside container and the installation seems to doing something privileged. So this time I start container with privileged hopefully this will lead to successful install gtk and will start chromium compilation.
Hope this will not kill my SSD  |

I will stop perusing this topic. rebuild failed again exact same way. Gtk failed with pkg_postinst (binary install) and chromium failed in configure phase, I think it is relate to gtk failure.

paluszak,
Thank you very much for the information. However I am not currently pursuing this topic any more. From I learn in the configuration it looks to me it will require targeted porting for RPI4 current state. The upstream code plus ebuild seems to targeting more modern ARM CPU. |

Chromium is in my Pi4 binhost.
My Pi4 test bed is down, having been scavenged for parts so it net been tested.
Feel free to try it.

Just a FYI. In order to test Neddy's build you are likely need to dig out a ebuild that match versions on the repo. (Please note, I am not suggest don't do it, Just want to point out up front so there be lesser confuse in case you try)
I just did a quick pull down and failed due to ebuild version mismatch, | Code: | 3f15d44242d1 ~ # emerge -agk1 --binpkg-respect-use=n --job 4 chromium

I was thinking someone later will surely come up a question about "it does not work for me. I setup binhost but it does not work" so just hope my post can save some of these questions.

Since I am not the smartest cookie in the jar I have do everything all over again because this test setup is in container and I did not give all the necessary configuration in the start of container so even I can install but I am not able to test run. Need to create a new container with right parameters and re-emerge everything again. |

I managed install chromium using Neddy's binhost.
However chromium start failed. I think the most significant failure is at the end of message "Illegal instruction (core dumped)", This usually indicate the compiler targeted wrong CPU architecture.
I ram this inside container so there are some errors may be relate to missing services but I expect the failure of start will be in different place.
Below is how the container start and execution

The missing /usr/lib64/dri/vc4_dri.so is most likely due to it is from my container host, I have very old (outdated) Gentoo. so it is possible the mesa are so different that it cannot load the share library. |

| For the illegal instruction failure, can you use the core dump to determine what instruction was illegal? Once that is known, you could check whether the illegal instruction is one that should have been prohibited by the Portage settings (indicating that the build system ignored the Portage settings) or if the Portage settings are too aggressive for this CPU. My guess is that either (a) this is in a library you got from Neddy's binhost, and his binhost targets a more capable CPU or (b) the build system ignored the settings it was given. |

Once that is known, you could check whether the illegal instruction is one that should have been prohibited by the Portage settings (indicating that the build system ignored the Portage settings) or if the Portage settings are too aggressive for this CPU. My guess is that either (a) this is in a library you got from Neddy's binhost, and his binhost targets a more capable CPU or (b) the build system ignored the settings it was given. |
I don't know how to do that Do I need to install gdb?
I saw Neddy's binhost /etc/portage/make.conf setting, it enable ~arm64 but the CFLAGS is | Code: | | COMMON_FLAGS="-mcpu=cortex-a72+crc -mtune=cortex-a72 -ftree-vectorize -O2 -pipe -fomit-frame-pointer -flto" |
And the CPU_FLAGS_ARM is | Code: | | CPU_FLAGS_ARM="edsp neon thumb vfp vfpv3 vfpv4 vfp-d32 crc32 v4 v5 v6 v7 v8 thumb2" |
To me it looks right for RPI4 which is Cortex-A72 + crc32 | /proc/cpuinfo: | | Features : fp asimd evtstrm crc32 cpuid |
This whole thing come out from when I review the chromium source code based on the reported error "dot_prod_permute_tbl undeclared". This is turn out due to chromium build system somehow decide the build need to add "-march=armv8.2+dotprod" which I have not yet able to find out why the build system need to go to this path.
I am not sure how Neddy's build circumvent the error, (I was not able pass that on my RPI4 container), may be because it is a Hawk system that build the binary which is truly armv8.2? |

gdb is not the only path, but in my opinion, it is the easiest path for this.
I lack the familiarity with ARM to evaluate your analysis, but your conclusions look plausible to me. Yes, if Chromium is forcing -march=armv8.2+dotprod instead of accepting the Portage settings, then it is possible (but not guaranteed) that a CPU which predates ARMv8.2 would encounter an illegal instruction here. Yes, if Neddy's hardware is truly armv8.2, then it is likely that his system could run this even with the unwanted forced -march value. |
