It kinda seems to me that when tasks need a quick and short CPU time, PDS is not giving that exactly.<br />Still, is anyone else experiencing this? Alfred, can You look into this, is this expected or is this a side effect of SCHED changes?<br /><br />BR, EduardoAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2963790426029213933.post-71451679529064476812018-11-19T13:18:59.996-08:002018-11-19T13:18:59.996-08:00Looking forward to next version thats for sure Alf...Looking forward to next version thats for sure Alfred :)<br /><br />Also seem there are stuff happening regarding that horrible "STIBP Patch" that was backported to 4.19.2. Im back to 4.19.1 atm tho. Some reads on lkml indicate Linus was not too happy with the solution.<br /><br />There seem to be a couple of patchsets in the brew that will kinda make this "on demand" thing, but some also talks about using the scheduler intelligently to determine if this process should use it.. Stuff like that.<br /><br />Any thoughts or insights?Sveinar Søplerhttps://www.blogger.com/profile/18401720133659243541noreply@blogger.comtag:blogger.com,1999:blog-2963790426029213933.post-73737342315066054372018-11-19T02:21:23.411-08:002018-11-19T02:21:23.411-08:00I meant a package.

Pls feel free to continue your tests. And...@Sveinar<br />Pls feel free to continue your tests. And BTW, there may be difference between MuQSS and PDS in ISO, and ISO handling in PDS has been simplified in 099c. I have a draft idea to improve ISO support, but it wouldn't happen till pending tasks are finished.Alfred Chenhttps://www.blogger.com/profile/03164306846702841944noreply@blogger.comtag:blogger.com,1999:blog-2963790426029213933.post-83630188077497955292018-11-17T15:43:29.030-08:002018-11-17T15:43:29.030-08:00My raspberry pi2 is running with PDS scheduler 7*2...My raspberry pi2 is running with PDS scheduler 7*24.Alfred Chenhttps://www.blogger.com/profile/03164306846702841944noreply@blogger.comtag:blogger.com,1999:blog-2963790426029213933.post-19990651974527216872018-11-16T01:05:33.691-08:002018-11-16T01:05:33.691-08:00Are there any binary kernel builds for ubuntu armv...Are there any binary kernel builds for ubuntu armv7l with PDS?Anonymoushttps://www.blogger.com/profile/06732867168326047410noreply@blogger.comtag:blogger.com,1999:blog-2963790426029213933.post-1623381399541768222018-11-15T12:49:43.732-08:002018-11-15T12:49:43.732-08:00True :)

Running with the same 4.19.2 kernel and mostly the same .config xept for ofc the MuQSS spesific options, and for me a change from 1000hz -> 100hz.<br /><br />But i am not sure if MuQSS and -ck patchset has seen any "changes" other than rebases for 4.19 kernel tho? Will keep testing.Sveinar Søplerhttps://www.blogger.com/profile/18401720133659243541noreply@blogger.comtag:blogger.com,1999:blog-2963790426029213933.post-64013115237249491222018-11-14T17:00:33.816-08:002018-11-14T17:00:33.816-08:00Built x64 and x86-UP the other night, and updated ...Built x64 and x86-UP the other night, and updated the Eee701 netbook yesterday; running great!

I don't know whether it's 4.19 or pds.<br />I'll try to observe whether 099d behaves the same or will see whether 4.18 + pds does better (maybe smth else changed).<br />I have no time at the moment to debug this and compare to vanilla etc. or other versions, deadlines on every project I'm working on. So I'll do minimum to get rid of problem currently. Do any of You have smth similar?<br /><br />BR, EduardoAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2963790426029213933.post-49339010733167760752018-11-12T13:04:08.485-08:002018-11-12T13:04:08.485-08:00Builds and boots fine as usual.

Had the same "random 1 second freeze" as 0.99c + i got a "soft lockup - CPU#9 stuck for 22s!" until i killed that.<br /><br />This soft lockup MIGHT be just a random happening, but sched_iso is not usable atm for wine+dxvk. Not really sure if its just me, as i use a custom compiled 4.19.1 kernel w/1000hz so it could be just something strange. However the last "sched_iso" bug report here indicated nVidia to be a possible culprit (nVidia GTX970 w/396.54.9 driver here).Sveinar Søplerhttps://www.blogger.com/profile/18401720133659243541noreply@blogger.comtag:blogger.com,1999:blog-2963790426029213933.post-49861460140664184292018-11-12T09:34:39.365-08:002018-11-12T09:34:39.365-08:00Builds and boots fine here, thanks.Builds and boots fine here, thanks.Oleksandr Natalenkohttps://www.blogger.com/profile/12098091624630953604noreply@blogger.com
