The MacBook Pro even has two of them, and I'm pretty sure one of them is connected to the external ports. On the Dell though this seems to be the port that connects to the DRAC.

Oh, and I wanted to mention something else that I'd forgotten about but stumbled across again the other day while debugging servers: Xen supports writing console messages to a special kind of USB port: "console=dbgp" indicates that Xen should use a USB debug port. http://xenbits.xenproject.org/docs/4.11-testing/misc/xen-command-line.html There's more about it in this thread: https://lists.xenproject.org/archives/html/xen-devel/2009-03/msg00436.html https://lists.xenproject.org/archives/html/xen-devel/2009-03/msg00458.html Further of interest is that Xen also supports writing to both a COM port and the "vga" console simultaneously. Indeed it may support writing to "dbgp" at the same time as well. This is something I looked into for NetBSD/i386 some time ago, but never got it fully working. To me I think it would be super incredibly valuable for the boot code to be able to talk to both a serial port and the "pc" console simultaneously. It is less important for the kernel to do so, but it still would be nice. -- Greg A. Woods Kelowna, BC +1 250 762-7675 RoboHack Planix, Inc.

However what would be most generally useful, as opposed to ideal, would be for just the console output to appear on the first found USB serial adapter. So if the kernel can get far enough to probe a USB serial port, then it should dump the message buffer, and continue to copy everything added to the message buffer, to that USB serial device. That's the first and most important step. Make it simple, easy, and obvious how to capture all kernel messages on a modern machine without having to get all the way to the point where one can run "dmesg". Further allowing that port to be attached as the console would be "nice but not quite as necessary". Now ideally the kernel should make the best attempt to identify the first possible USB serial port as early as possible, and attach it as console, so that nothing can be missed, and so that any other bugs in device probing, etc., etc., etc., would not prevent use of DDB on this USB serial console. Even better would be to find out if the platform firmware can do some or all of this, and then to use that code both for the boot loader and the kernel console. E.g. on an EFI system, perhaps through a custom EFI driver? And for uBoot systems too? -- Greg A. Woods Kelowna, BC +1 250 762-7675 RoboHack Planix, Inc.

I have not seen any so far (none of the new ones come with > an external connector of course, but they can be added easily unless it is > a notebook). Not a stupid question at all. Short answer is "yes", unfortunately. I don't buy brand-new boards very frequently, so it hasn't completely impacted me yet, but dropping the connector already seems common, and last time I shopped ITX for a small home server I ended up eliminating a lot of candidates (maybe over 50%) because they didn't even have the COM header on the board so I could add the connector myself. I'd always hoped that, if anything, the "legacy" db9 connector might over time start turning into rj45 serial connectors with telco pinouts ala Cisco and other devices. But it doesn't seem a likely trend for PC systems at this point. Even some of the recent name-brand "enterprise" rackmount systems at $work didn't come with a serial console port out the back -- it was an add-on option at most. The vendors presumably want to push their GUI BMC paradigm, with the graphical server management goop. Some of it is admittedly nice functionality, but a lot of it is simply overkill when a good ole serial port would be fine. I think it's already been mentioned downthread, but other systems in this category are smaller devices like NUC and similar. The low power (noise, heat etc.) profile makes those attractive, but without a serial console they're not as nice. Best I've been able to do with a couple of those is a USB-serial terminal (!=console) which is better than nothing, e.g. to fix a broken network config, but doesn't help when you need to interact with boot stuff. Cheers, sr.

USB is horrible from this persective; you need quite a lot of infrastructure to do, well, pretty much anything over USB. Take a look at the code sometime. In the particular case of the console, you'd also have to figure out what to do with the console if the hardware goes away. It's one of the reasons I dislike USB, and closely related to most of the others. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTMLmo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
NetBSD-7.0 boots OK and NetBSD-8.0 hangs/crashes during boot on a MacBook7,1
So, in my ongoing NetBSD on a MacBook saga NetBSD-7.2 boots fine from USB on the MacBook Pro (MacBook7,1) (with the help of rEFIT on a second USB stick). NetBSD-8.2 and newer, including the most recent -current, hangs during boot and the kernel messages appear to have torn video: http://www.planix.ca/~woods/macbookpro-netbsd-boot-fail.jpg However today I discovered that NetBSD-8.0 will often boot with the kernel messages properly visible in nice green on black in a full 52(?)-line display, but it hangs or crashes. (It is not reliable at booting though -- sometimes the boot loader just hangs without printing anything.) If the boot loader does work though, and if I boot "normally" it just hangs, with the last message being: pci0 at mainbus0 bus0: configuration mode 1 The caps-lock button is dead so I think the machine is well and truly frozen in a CPU loop (the CPU is hot, the fan runs fast). I'm guessing NetBSD-8.2 and everything more recent is also hanging at this same spot, but with the busted video mode it's hard to tell for sure. If I boot 8.0 with ACPI turned off (boot option #2 or from the boot prompt "boot -2"), it crashes into ddb after getting a bit further, but there are many errors about not being ablt to map PCI interrupts. If I boot 8.0 with "-vx", there are quite a number of "invalid config space" messages after the pci0 attachment: pci0 at mainbus0 bus0: configuration mode 1 acpi0: MCFG: 000:00:0: invalid config space (cfg[0x100]=0x, alias=false) The second and third numbers change in each following message, and in two of those messages the cfg[0x100] number is 0x. So it looks like ACPI is necessary, but support for using it in this MacBook7,1 is broken somehow. I can post a full-res photo of the screen in one or more or all of these states it someone wants to see it. In any case, what might have been changed after 8.0 that broke the video output? Where do I look? Is amd64 video now the genfb(4) device code? Or is it still vga(4)? If it's genfb(4), then I do see commits about doing anti-aliasing, and maybe the video junk I see could possibly be explained by such a thing. If I can get 7.2 installed (likely), so that I need only drop a kernel in place instead of building the whole installimage and writing the damn slow USB stick with a whole install image every time, then maybe I'll be able to try bisecting changes to get the video working right again. I really wish modern PC vendors were not still so bloody stupid with their firmware as to make it impossible to talk to them via a serial port of some kind (e.g. a USB serial adapter as console would be awesome!). That said, what would it take to wire the NetBSD console to a USB serial adapter? In lieu of that it would be nice if hitting ^S on the keyboard would at least pause the kernel messages from scrolling by during boot, but I get that such a thing might be a bit hard to arrange for in NetBSD. -- Greg A.
