I do notice that your NIC has a rev of 0x10 while mine is 0x0c. -- Kevin Oberman, Network Engineer, Retired I tried a 10.1-BETA also and it shows the very same symptomes as in 11.0-CURRENT. As Guido Falsi stated later in this thread, the device gets recognized but is inoperable after initialized and setup by the OS until the administrator takes some strange actions. In Guido's case a setting/resetting of NIC features helps, in my case I have to bring down the device first via ifconfig re0 down and then bring it up. After that, the NIC works as expected. This seems clearly to be a bug in the driver code and it might indeed have to do something with a new revision used, but the NIC is since at least a year on the market and floating around (my laptop was manufactured in April of this year). Well, I hope this report doesn't get lost, so I filed a PR. Oliver signature.asc Description: PGP signature
Re: uefi boot on Apple Mac
I finally make MacBookPro 11,3 UEFI boot successfully: 1. copy boot1.efi to /EFI/boot/BOOTx64.efi in EFI partition 2. Create a small UFS partition in internal SSD, and installworld and installkernel. 3. Without USB stick, then system really can boot, although the loader still stop at: Start @ 0x802d9000... 4. I can ssh log in and found that culprit is XHCI USB controller does not work in UEFI mode. 5. Xorg and nvidia driver also works. 6. verbose boot log can be found at: http://sw.gddsn.org.cn/freebsd/uefi-messages.txt Cheers, Huang Wen Hui 2014-08-10 16:44 GMT+08:00 Anders Bolt Evensen andersb...@icloud.com: If you're interested, you can try out the following ISO: https://www.dropbox.com/s/srbunx0agrokcs3/freebsd- current-uefi-bios-amd64.iso The image was built on Friday 8th of August for the amd64 platform. I tested out the EFI part on VirtualBox (UEFI 2.X) and my MacBook Pro 17 inch from 2011 (EFI 1.10), and as far as EFI goes, I successfully booted the image on both my Mac and VirtualBox (however, booting the image from BIOS using my Mac was a different story).

After the execution of the GSO, the packets, that are passed to the device driver, are smaller (or equal) than MTU, so the TSO is unnecessary. For this reason the GSO doesn't look neither ifp-if_hw_tsomax nor hardware segment limits. The GSO is very useful when you can't use the TSO. How does GSO affect IPFW, specifically the libalias(3)-based, in-kernel NAT? The ipfw(8) man page mentions that it doesn't play nicely with hardware-based TSO, and that one should disable TSO when using IPFW NAT. Will the software-based GSO play nicely with IPFW NAT? Will it make any difference to packet throughput through IPFW?

+.Sh NAME
+.Nm libthr
+.Nd FreeBSD implementation of the Posix threading library
+.Sh LIBRARY
+.Lb libpthread
+.Sh DESCRIPTION
+The man page documents the quirks and tunables of the
+.Fx
+implementation for the
+.Lb libpthread .
+When linking with the
+.Li -lpthread ,
+the run-time dependency
+.Dv libthr.so.3
+library is recorded in the produced object.
+.Pp
+The library is tigthly integrated with the Run-time Link-editor
+.Xr ld-elf.so.1 1
+and
+.Lb libc ,
+all three components must be built from the same source tree.
+Mixing
+.Dv libc.so
+and
+.Nm
+libraries from different versions of
+.Fx
+is not supported.
+The run-time linker
+.Li ld-elf.so.1
+has some code to ensure backward-compatibility with older
+.Nm .
+.Sh MUTEX ACQUISITION
+The locked mutex (see
+.Xr pthread_mutex_lock 3 )
+is represented by a volatile variable of type
+.Dv lwpid_t ,
+which records the global system identifier of the thread
+owning the lock.
+The
+.Nm
+performs a congested mutex acquisition in three stages, each of which
+is more resource-consuming than the previous.
+.Pp
+First, the
+.Li spin loop
+is performed, where the library attempts to acquire the lock by
+.Xr atomic 9
+operations.
+The loop count is controlled by the
+.Ev LIBPTHREAD_SPINLOOPS
+environment variable.
+.Pp
+If the
+.Li spin loop
+was unable to acquire the mutex, the
+.Li yield loop
+is executed, performing the same
+.Xr atomic 9
+acquisition attempts as
+.Li spin loop ,
+but each attempt is followed by yield of the CPU time of the thread by
+.Xr

I tried to retrieve informations about the settings and implementations in the lenovo E540, but I guess the only answer can be given by developer documentation. I can not figure out how the GPU is attached to the system. The technical specifications do not mention the requirement of a iGPU and shared memory - as Optimus would require. But extrapolating from that shit-covering public relations talking at nVidia's site I guess the GT 740M is definitely a shared memory solution and requires the presence of the iGPU. That would explain why the nvidia BLOB is detecting the GPU, but can not find any physical display socket, not even the built-in LCD. They're maybe wired all throught the Haswell's HD4600 iGPU? Anyway, I also tried to configure X11 as HD4600 only and X11 doesn't work properly: it doesn't even start up and loading the intel driver complains about a missing device - preceeded by a lot of /dev/dri errors.

FreeBSD-11.0-CURRENT on ARM: performance and load average
Hello everyone, Recently, I encountered a problem with -CURRENT on an ARM board (cubieboard2 to be precise). The problem was that the load average was above 2. Including the fact that the board has 2 CPU cores, that's strange. Also, the network throughput was way too slow: from 3 kilobytes per second earlier to 20..50 about now. Here's a workaround for that: sysctl kern.eventtimer.periodic=1 With that, the network performance increased while LA decreased to a decent 0.3..0.5. -- wbr, Maxim Filimonov c...@bein.link ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Here's a workaround for that: sysctl kern.eventtimer.periodic=1 With that, the network performance increased while LA decreased to a decent 0.3..0.5. Since it's happening only on that hardware, there's a good chance the problem is in the allwinner a10/a20 clock driver, not in the general eventtimer code. In fact, looking at the code it appears that a divide-by-16 is being set in the hardware, but not accounted for when setting the frequency of the eventtimer. Hmm, it should affect the timecounter too, in which case you'd see time-of-day advancing 16x too fast. If ntpd is running it would need to step the clock pretty frequently, which would show up in syslog. I don't have hardware to test on, please see if the attached patch makes a difference. -- Ian Index: sys/arm/allwinner/timer.c === --- sys/arm/allwinner/timer.c (revision 271909) +++ sys/arm/allwinner/timer.c (working copy) @@ -199,7 +199,7 @@ a10_timer_attach(device_t dev) val |= TIMER_ENABLE; timer_write_4(sc, SW_TIMER_IRQ_EN_REG, val); - sc-timer0_freq = SYS_TIMER_CLKSRC; + sc-timer0_freq = SYS_TIMER_CLKSRC / 16; /* Set desired frequency in event timer and timecounter */ sc-et.et_frequency = sc-timer0_freq; ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

If an option to disable the Nvidia GPU is not present, some people have reported success with an xorg.conf that uses only the intel driver and ignores the Nvidia hardware. Thanks Warren. But this sounds even more frustrating now. I look around the web even at Lenovo's support forum. Many people report the GT 740M nVidia adaptor as a discrete adaptor with Optimus technology and everything sounds to me like it can be selected exclusively. What you describes is that I definitely need to use the HD4600 iGPU on FreeBSD in the first place since the nVidia hardware is a kind of appendix to the HD4600. Optimus started out that way, but they might use the same name now for models where the additional GPU is a full discrete adapter. Anyway, I also tried to configure X11 as HD4600 only and X11 doesn't work properly: it doesn't even start up and loading the intel driver complains about a missing device - preceeded by a lot of /dev/dri errors. This indicates to me, in a naiv manner, that this HD4600 isn't recodnized by the kernel, either. I do not see any kind of vga0: entry in the kernel log when enabling Integrated Graphics only in the laptop's UEFI/Firmware. When enabling nVidia Optimus, a recognized vga0: device shows up. Whoops, HD4600 is Haswell. The intel driver on FreeBSD does not support Haswell video yet. Is there any kind of status update on Haswell? The wiki has the last update 11 months ago and it's becoming a major useability issue for the operating system. -Nathan ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Re: FreeBSD-11.0-CURRENT on ARM: performance and load average
On Saturday 20 September 2014 13:24:08 Ian Lepore wrote: Since it's happening only on that hardware, there's a good chance the problem is in the allwinner a10/a20 clock driver, not in the general eventtimer code. In fact, looking at the code it appears that a divide-by-16 is being set in the hardware, but not accounted for when setting the frequency of the eventtimer. Hmm, it should affect the timecounter too, in which case you'd see time-of-day advancing 16x too fast. If ntpd is running it would need to step the clock pretty frequently, which would show up in syslog. I'm running FreeBSD-current on the board right now, the time is just fine. I don't have hardware to test on, please see if the attached patch makes a difference. Well, it did: with the patch applied, the time ran about 60 times as fast as it should have. I didn't notice any changes with load average, though: maybe it's because I forgot to turn that sysctl setting I set before back to 0. wbr, Maxim Filimonov c...@bein.link ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Setting it to any value results in the main thread stack left as is, and other threads allocate stack below the area of RLIMIT_STACK. Try it. I do not want to set this behaviour as default. Is there a reason this should not be the default? Looking at the getrlimit() page on the OpenGroup?s site they say: RLIMIT_STACK This is the maximum size of the initial thread's stack, in bytes. The implementation does not automatically grow the stack beyond this limit. If this limit is exceeded, SIGSEGV shall be generated for the thread. If the thread is blocking SIGSEGV, or the process is ignoring or catching SIGSEGV and has not made arrangements to use an alternate stack, the disposition of SIGSEGV shall be set to SIG_DFL before it is generated. Does posix say something different? I ran into this issue when debugging a segfault on Postgres when running an (arguably quite bogus) query that should have fit within both the configured stack rlimit and Postgres? configured stack limit. The Postgres backend is really just single threaded, but happens to pull in libpthread due to the threading support in some of the libraries it uses. The segfault definitely violates POLA. ? Justin I am conservative to not disturb the address space layout in single go. If enough people test this setting, I can consider flipping the default to the reverse. I am still curious why the things were done in this way, but nobody replied. I suspect it was done out of reasons of being overly conservative in interpreting RLIMIT_STACK. I think it is quite surprising behavior though and would rather we make your option the default and implement what the Open Group says above. that is my memory.. The transition from a non threaded app to a threaded app with one thread is sort of an undefined area.

Including the fact that the board has 2 CPU cores, that's strange. Also, the network throughput was way too slow: from 3 kilobytes per second earlier to 20..50 about now. Here's a workaround for that: sysctl kern.eventtimer.periodic=1 With that, the network performance increased while LA decreased to a decent 0.3..0.5. I'm just started to experiment with cubieboard (1) as well. I've also noticed poor network performance at first, however later (without any tuning) it gave out 111 kBps. kern.eventtimer.periodic doesn't seem to affect it. I've also played with clocks a bit, and was able to increase CPU rate 3x by configuring PLL1.

x11/nvidia-driver (340.24/340.32/343.13): nvidia BLOB doesn't recognize any display socket on Lenovo E540/UEFI and FBSD CURRENT
Hi. Very preliminary question, but not mentioned before if I haven't missed it. Have you disabled Optimus? If not, you need to disable it (or definately select nvidia discrete GPU) in BIOS / UEFI firmware, as currently any version of nvidia proprietary driver for FreeBSD does NOT support Optimus. Please read /usr/local/share/doc/NVIDIA_GLX-1.0/README for detail. (The location could be different if you installed nvidia driver WITHOUT using ports nor pkg.) At least, my ThinkPad T420 has an option to select Optimus / internal intel GPU / nvidia discrete GPU, and I need to select nvidia discrete GPU to use x11/nvidia-driver.
