In­ter­est­ing Sum­mer for FreeBSD

Now that we have (or “soon will have”) an of­fi­cial FreeBSD [1] blog, I de­cided to give this kind of elec­tronic and pub­lic di­ary a try. At least to re­port the status and pro­gress of some FreeBSD [2] re­lated pro­jects [3] I’m in­volved in.

A lot happened in the last days. We’re past the dead­line of the Google Sum­mer of Code rat­ing pro­cess and now the lucky stu­dents are chosen. It wasn’t easy. We had more than 120 pro­pos­als (out of ~6400). From those we where will­ing to mentor 40 – 50 (based upon our re­sources and the qual­ity of the pro­pos­als). Google gran­ted 14 to us (a big thank you to Google!). I ex­pect an of­fi­cial an­nounce­ment “soon”. Hope­fully some of those stu­dents Google wasn’t able to fund are will­ing to work with us re­gard­less of the money [4], there are a lot of very nice pro­pos­als (I will add some items to the ideas list [5] based upon them later). We’re at least will­ing to provide the same amount of ment­or­ship as if they where se­lec­ted.

I will work with two stu­dents. One of them will work on syncing the OSS API from re­cent re­leases from 4Front with our sound sys­tem. The other one will work on im­prov­ing the linuxolator. I will an­nounce this on the cor­res­pond­ing mailing­lists after the of­fi­cial an­nounce­ment. ATM we need to do some ad­min­is­trat­ive stuff (hand­ing out ac­cess to the wiki and per­force [6], set­ting up email ali­ases, …).

I already mailed some gen­eral guides to the stu­dents (note to ment­ors: it’s in the wiki on the “hid­den” and re­stric­ted to ment­ors SoC page). For the sound stuff I don’t have a nice TODO list, but luck­ily the stu­dent already in­vest­ig­ated the 4Front stuff for the pro­posal and is eager to start the work (ba­sic­ally this gives us the user­land [7] in­ter­face for multi-channel mixer sup­port). Re­gard­ing the linuxolator im­prove­ments the stu­dent has a little bit less luck. I com­piled a nice TODO list which is based upon his own pro­posal and all the vari­ous things I know about the linuxolator (PR’s, mes­sages on emulation@, private con­ver­sa­tions, things we no­ticed while work­ing on the up­date of the linux [8] base to a re­cent Fe­dora Core, …). I will be im­pressed if he man­ages to do everything on the TODO list (don’t worry, he knows that not everything has to be done to de­clare “suc­cess” to Google).

Both of them may be can­did­ates for a com­mit bit (not within the SoC, but maybe later), both are eager to do the work, in­ter­ested, mo­tiv­ated, and don’t need hand-holding.

Fur­ther news in the area of the sound sys­tem: Ar­iff told me he is work­ing on multi-channel and en­di­aness issues/support, and I may be able to com­mit two more sound drivers to the tree. One driver is the emu10kx driver cur­rently avail­able in the Ports Col­lec­tion, and the other one is a driver for some envy24 chips. Cur­rently I’m in con­tact with the au­thor of the emu10kx driver and a vo­lun­teer who wants to im­prove an ex­ist­ing envy24 driver (au­thor of the driver con­tac­ted; since it’s BSD li­censed, this is a “don’t be evil” ac­tion).

And some news re­gard­ing the user­land part of the linuxolator: We’re wait­ing for a repo-copy form linux_base-fc3 to linux_base-fc4 [9]. It seems FC4 is com­pat­ible enough so that we can dir­e­clty move from Red­Hat 8 to FC 4. FC 5 is out of the game for a while, it doesn’t want to run with the old linux ker­nel [10] ver­sion our linuxolator an­nounces. Chan­ging the ver­sion via the sy­sctl doesn’t help (prob­ably be­cause of the changed se­mantic of the linux clone sy­scall between 2.4.x and 2.6.x), so it has to wait un­til the linuxolator SoC fin­ishes.
