Re: drm2 regression: backlight adjustment on ivybridge no longer works
ugh, so because i can't sleep, I read the Linux i915 history for backlight changes. Turns out if I disable bit 30 in ivb_pch_pwm_override() to register BLC_PWM_PCH_CTL1, the acpi video setting works. The keyboard settings still don't, but I'll worry about that later. Bit 30 in the linux drm code is: #define BLM_PCH_OVERRIDE_ENABLE (1 30) The linux dri code doesn't set that for ivybridge - only for broadwell. (also, the linux driver has POSTING_READ() which I'm guessing is to ensure things made it out to the device and have been flushed before doing another IO operation.) I have my (via sysctl) panel backlight control working again. -adrian ___ 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
System-On-Module
Hi Of all the low power, high-spec system/computer-on-modules out there which have best support for FreeBSD? MEN Variscite Technologic system Adlink etc. What I am looking for is a system with roughly this specs ARM or x86, 64bit if possible. 2-4 cores 1.5-2.0 GHz 2 GB RAM ~16 GB Storage USB 3.0 PCB size about one to two credit cards. I wish to minimize the amount of porting needed so I am very grateful if someone has good insights in this area. And of course, it would help a lot if it was a manufacturer who is willing to provide datasheets to make porting possible..

Re: OptionalObsoleteFiles.inc completeness improvement, try 2

The patch is complete, see https://reviews.freebsd.org/D1600.
- With it, for all knobs from src.conf(5) there are no difference in
file tree contents between `KNOB make installworld` and `make
installworld KNOB make delete-old delete-old-libs`
- Note that some OLD_DIRS were removed - they were incorrect as most
directories are installed unconditionally by mtree. Since empty
directores are not really needed, the install process should be
probably improved
- Some knobs which delete massive number of files (WITHOUT_MAN,
WITHOUT_INCLUDES) were implemented with
FILES!=find ...
OLD_FILES+=${FILES}
(similar construct was already used in WITHOUT_TESTS)
I though of more effective implementation for this, such as
introducing OLD_DIRS_RECURSIVE to fill from OptionalObsoleteFiles,
in which delete-old will just call `find ... -delete`
- Unneeded conditions such as
.if ${TARGET_ARCH} == amd64 || ${TARGET_ARCH} == powerpc64
OLD_FILES+=usr/lib32/...
.else
were not removed yet. Maybe with the next patch.

Re: System-On-Module
Thanks a lot guys. I can specify a bit more details. We don't need any sd-card, sata or external storage. Just the internal eMMC is enough. Display output can be DSI, LVDS or something that can easily be serialized to transfer over 2 wires. If WiFi and Bluetooth 4.0 is on the board that'll also be great. And of course, it would be helpful if the said board also is available as development kit... If the first tests are ok (tests can be done using Linux if FreeBSD doesn't run out of the box) we're looking to buy a larger amount, at least 1000 to start with. We are flexible about prize and size of the board. Atom is preferable over imx6, but I'll check out what you recommended. Thanks again! Ps.

Don't get confused with the wandboard module+carrier board, which is the normal offer (and in small volumes often cheaper than the 10x module pack). The Wandboard module alone is extremly similar to the Kontron modules in your link. They don't have eMMC (maybe some of the TechNexion have), but they do have a micro-SD on the module itself, plus SDIO on the module header. eMMC can have a higher transport speed because it allows for 8bit instead of 4bit and as soldered chip it has different issued than a socketed card, but otherwise they are very similar in design. The 2 and 4 core Wandboards have BT/WLAN on module, but it is done by SDIO, for which FreeBSD (to my knowledge) has no support yet. -- B.Walter be...@bwct.de http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm. ___ 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

That's similar to the EDM module that wandboards use: http://www.technexion.com/products/edm/edm-som/edm1-cf-imx6 You can buy the EDM modules directly from Technexion if you're willing to buy quantity, or through resellers like Digikey. The EDM modules from technexion are compatible with the wandboard carrier boards, so you can use a few cheap wandboards as devel and eval boards (or you can buy the overpriced fairyboard carrier from technexion that has PCIe connectors that wandboard lacks). We're using these modules at $work, and that's basically the path I took... I started with a wandboard and got freebsd running on it, and once it got past the proof of concept stage (the minimum set of drivers for the imx6 devices we need, and reasonable freebsd stability -- I had a board running a stress test with 2 months of uptime) we designed our own motherboards with EDM sockets on them. -- Ian ___ 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

The imx6 manuals include an errata list, so it would be good to check that for anything specific that would matter to your projects. For the devices we use in our products everything is good so far with the hardware. That's emmc, sdcard, ethernet, i2c, uarts, usb, and lots of gpio (inputs and outputs). The ethernet is gigabit but has a known limitation of 40MB/s due to the bus it's connected to in the chip. (But hey, it's documented so it's not a problem, right? :) You mentioned video, and we don't have that working on freebsd imx6 yet, but there's not a ton of work to do. There's a framebuffer driver for imx5 and it has pretty much the same framebuffer hardware. Getting video output to a TTL LCD is probably just hours of work.

Re: System-On-Module
Ah now I see it has EDM connection. I didn't look carefully enough. All the images are with the expansion board attached.. Spec-wise and portability-wise it seems like a good option but my hardware guy keeps warning me about Freescale that they often have hardware bugs and rather than fixing the bugs they pretend they are not there.. In other words, Freescale is good for software developers because of open documentation but not so for hardware manufactures.

That's similar to the EDM module that wandboards use: http://www.technexion.com/products/edm/edm-som/edm1-cf-imx6 You can buy the EDM modules directly from Technexion if you're willing to buy quantity, or through resellers like Digikey. The EDM modules from technexion are compatible with the wandboard carrier boards, so you can use a few cheap wandboards as devel and eval boards (or you can buy the overpriced fairyboard carrier from technexion that has PCIe connectors that wandboard lacks). We're using these modules at $work, and that's basically the path I took... I started with a wandboard and got freebsd running on it, and once it got past the proof of concept stage (the minimum set of drivers for the imx6 devices we need, and reasonable freebsd stability -- I had a board running a stress test with 2 months of uptime) we designed our own motherboards with EDM sockets on them. -- Ian -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- 秘密保持について：この電子メールは、名宛人に送信したものであり、秘匿特権の対象となる情報を含んでいます。 もし、名宛人以外の方が受信された場合、このメールの破棄、およびこのメールに関する一切の開示、 複写、配布、その他の利用、または記載内容に基づくいかなる行動もされないようお願い申し上げます。 --- CONFIDENTIALITY NOTE: The information in this email is confidential and intended solely for the addressee.

The imx6 manuals include an errata list, so it would be good to check that for anything specific that would matter to your projects. If you use a prebuild module then you don't get much in touch with the freescale chip fropm the hardware side. On the other hand, there are countless iMX6 boards out there with schematics online. My recently bought Novena even came with printed schematics and they open sourced the HW design files as well. I don't think there are hidden surprises on the hardware side.

The one I already got are board only (with some FPGA breakout, ...). They have HDMI though. But I'm also awaiting for the one with case and LCD panel. Not to forget that I have a fairy EDM carrier with LCD already. That said I'v always wondered how much work is it to get the camera interface running, since the Hummingboards can connect to the RPi camera modules.

On the other hand, you generally can't buy Technexion modules one at a time. Last time I checked they were minimum order 10 pieces even from resellers like Mouser and Digikey. Another small-board imx6 possibility is the Hummingboard from SolidRun.
