DIST_SUBDIR not working with MASTER_SITE_OVERRIDE
Hi everybody,
I recently wanted to install some gnome stuff from ports. In order to
boost the download speed, I did something like this:
make MASTER_SITE_OVERRIDE=ftp://ftp1.ro.freebsd.org/pub/FreeBSD/distfiles/
as documented in the Handbook. However, many gnome packages seem to have
DIST_SUBDIR in their Makefile, but MASTER_SITE_OVERRIDE doesn't care. This
makes installing ports (with many dependencies) from known non-default
sources very hard.
The following patch addresses this problem. As a side-effect, if somebody
does not have distfiles structured as on a FreeBSD mirror (a rare case I
would say) he will have to find a workaround.

Cristian, good day. Mon, Jan 21, 2008 at 11:06:26PM +0200, Cristian KLEIN wrote: Eygene Ryabinkin wrote: But what protocol is selected? From your Xorg log I assume that it is either event, auto-dev or not set at all. I just ran into the same problem. In xorg.conf I explicitly told the synaptics driver to use psm and /dev/psm0, but the error message would suggest that it uses event. Also, I tried to change the source code of the synaptics driver (synaptics.c) and hard-coded psm as the only driver, no matter what xorg.conf says. Synaptics still would not start, but this time complaining that no device was specified. Please note that I had Device in my xorg.conf, but the error suggests that the driver ignored it. Could you please provide your Xorg configuration file and the Xorg logs for the run when you had hardcoded psm driver. It will also be good to see the modified Synaptics driver source file.

Dell XPS 1530 - Network card issue - Marvell 88E8040
(I originally addressed this to the freebsd-hardware, but got no response, so please forgive me for reposting this here!) Hi, It appears as if the Marvell 88E8040 is not yet supported by FreeBSD and specifically the msk(4) driver. I would just like to know if there are any plans on adding support for the above mentioned NIC. Normally I wouldn't even bother asking, and just shrug and say, tough luck they don't support it... next distribution. Thing is, I really, really like FreeBSD. I'm kind of a GNU/Linux guy, but I've never managed to settle for a distribution and have moved from one to another, never quite finding something that works with me, and not against me. Then I tried FreeBSD, actually I just read much of the available documentation and I was converted. _THIS_ is how documentation should be written; clear, concise, to the point and most of all, USEFUL! Thank you! So, my point is that I really want this to work out. I'm willing to give as much time as necessary to get this driver working. Whether it's just a little Device_ID change in the source, I don't know. However, if anyone is up for helping me getting this to work, I'll provide whatever information I can. Many thanks, and keep up the fantastic work on the FreeBSD operating system.

I would just like to know if there are any plans on adding support for the above mentioned NIC. I'd like to add support 88E8040(Yukon2 FE+ PCIe Fast ethernet controller). I don't think just adding a PCI id is sufficient to make it work but it would be even better if you can send me the 'pciconf -lcv' output to me. I think one of the serious issue of Yukon2 FE+ is introduction of new descriptor format and additional bugs for the chip/phy as other variants. Since there are no documentation for controller/phy hardware, it may take longer than you would expect to see a working/stable driver. I guess disabling TSO and checksum offload may make it possible to write a minimal driver for the hardware. I'll let you know when I have code to test. I cannot say the code written by me would work as I don't have that hardware. Normally I wouldn't even bother asking, and just shrug and say, tough luck they don't support it... next distribution.

For once, it's something I expected :) I just hope it isn't one of those cases where Kris absolutely cannot reproduce it and arrives at numbers in favour of FreeBSD :) (just joking here, absolutely no ill feelings involved). Harumph :) The first step is that we need to understand where the application is spending its time. Hopefully Stefan or someone else will be able to test it under hwpmc. It would be helpful if you post exact command line arguments from all cases. The other thing that bothers me is, that under freebsd is quite easy to get: [send_ip] sendto: No buffer space available It happens almost always on my laptop just few seconds after I start hping with timecounter=TSC I'm not sure, but from what I understood of Robert Watson's explanation in the big ZFS thread on -current, maybe increasing kmem_size (exactly as for ZFS...) could help you with these buffers. It is the socket buffer that is filling up. Either the application is not increasing it to large enough size or the default maximum is too low (Linux may set a larger default). Try increasing kern.ipc.maxsockbuf and confirming with the source and/or ktrace that it is doing the right setsockopt() call.

update slices on (a)cd devices
Hi, I ask the same question some day on -questions before but got no usefull answer. Since it is also more technical related I try it here again. I created a dvd with two slices a and b. (Don't ask for the reason - it is a test for my backup system) This slices are ufs formated and gbde encrypted. However - if I insert the DVD (and also a read access is done) the device nodes acd0a and acd0b are not created automaticly. But if the DVD is inserted *before* boot this two nodes are there and stay even if I insert a normal DVD without slices. An other way to update the device nodes is to detach an attach the ata channel with atacontrol while the sliced DVD is beeing inserted. But this is not very smart. (In particular if there is i.e. a second device at this channel that is then disconnected too.) A similar way it to reload the atapicam modul. In this case the cd0* device nodes are updated. The problems are the same as with atacontroll de-/attach. So I'am searching for a better way to tell the kernel/devfs to update the device node list of the atapi devices. Unfortu- nately I couldn't find a appropiate ioctl in the source of atacontrol. Since I didn't understand the conecpt of geom fully now I'm not sure whether geom also handle the single (a)d[0-] and (a)cd[0-] devices and if there is maybe a geom command for the slice reread Thank you, Martin L. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: DIST_SUBDIR not working with MASTER_SITE_OVERRIDE

Hi everybody,
I recently wanted to install some gnome stuff from ports. In order to
boost the download speed, I did something like this:
make MASTER_SITE_OVERRIDE=ftp://ftp1.ro.freebsd.org/pub/FreeBSD/distfiles/
as documented in the Handbook. However, many gnome packages seem to have
DIST_SUBDIR in their Makefile, but MASTER_SITE_OVERRIDE doesn't care. This
makes installing ports (with many dependencies) from known non-default
sources very hard.
I used to do something similar to this by setting it in /etc/make.conf.
The only downside is if DIST_SUBDIR is not set you get paths that don't
look pretty, e.g.:
ftp://ftp5.freebsd.org/pub/FreeBSD/distfiles//some_distfile.tgz
Instead, I added something to my /etc/make.conf similar to:
.if defined(DIST_SUBDIR)
DIST_SUBDIR_OVERRIDE=${DIST_SUBDIR}/
.else
DIST_SUBDIR_OVERRIDE=
.endif
MASTER_SITE_OVERRIDE=ftp://ftp5.freebsd.org/pub/FreeBSD/distfiles/${DIST_SUBDIR_OVERRIDE}

HP Color Laserjet 1600
We have a networked HP Color Laserjet 1600 on a print server (could also be shared on a Windows XP Pro box). We want to print text (plain black) with a letter head (in color). We created the letterhead using Microsoft Word, and printed it to a file. We were hoping that when we wanted to print out text with the letter head that we could just queue the output from Word, followed by the text. The thinking being that the file produced from the Print-to-File option of word, would be native PCL, and then we could just throw the text in afterwards. When we try to print the letter head file, we get the PCL commands, as text... Alas, this is not as simple as we had hoped. Any suggestions as to how to produce the desired result would be appreciated.

zfs plugins
Has any thought been given to the growing number of zfs plugins on solaris? In particular, they have an encryption plugin that functions similar to zfs compression, but it seems useful to consider their plugins...

Re: Hardware support for AMD Geode CS5536 audio?
Hi, re: I'm hoping someone will be able to help me out with the audio is the Geode CS5536. Those AMD Geode systems with the CS5536 look almost cheap enough to afford one for each hand. I'll look into upgrading the 5530 audio driver for the 5536, but it will take sometime. If someone does it over the weekend, or somesuch, let me know...
