wait a sec - before the dri2 update, what exactly were you doing? What happened when you loaded i915kms? Nothing should've been found and no i915 driver should've been running There's no haswell support for i915kms, so it shouldn't have worked /at all/. You should've just gotten either vt(4) or sc(4) + vesa as a console, and VESA graphics. As a workaround, you can just not load i915kms, or patch i915kms to not detect your haswell chipset. -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

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. Any experiences with this? 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. Getting it to an LVDS LCD or HDMI probably needs days of work (entire drivers written, potentially, I haven't looked into it). Some audio support was recently committed, but I don't know much about it yet. -- 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 laptop is equippted with a Intel i5-4200M CPU with integrated HD4600 iGPU. Recent update of CURRENT and loading of i915kms.ko turns the display immediately blank. Laptop is accessible via ssh and network. Only display is dead. I suppose this a bug? Yes, very much so. What's your svn revision and can you please create a bug for this issue? Please also read the thread titled drm2 regression: backlight adjustment on ivybridge no longer works first to see if the symptoms describe there match your's. That is useless, since the reported symptomes do not apply to non-working Haswell. Since the last update of the OS - today, CURRENT 277900, the high res console is gone and has fallen back to the 800x600 pixel. The same with the X11 server's display resolution. I can not use VESA driver on the Lenovo ThinkPad E540 with i5-4200M, since it doesn't startup. I have to use xf86-video-scfb which is a pain in the ass. An alternative is to use Ubuntu on the Lenovo E540 and L540 we purchased. pgpBGSe3I4P8U.pgp Description: OpenPGP digital signature
