We'll see more in coming days.<br /><br />BRk EduardoAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2963790426029213933.post-88137542571269335252018-07-10T22:23:46.447-07:002018-07-10T22:23:46.447-07:00Interesting.

But in 4.17, there are code changes from mainline, so give it another try, but looks like the accounting issue has been gone. So NOHZ_FULL, I'd like to said NOHZ_FULL works in PDS but it's not fully tested, if you find something unexpected under NOHZ_FULL, pls let me know.Alfred Chenhttps://www.blogger.com/profile/03164306846702841944noreply@blogger.comtag:blogger.com,1999:blog-2963790426029213933.post-3583860506848187802018-07-10T22:15:04.395-07:002018-07-10T22:15:04.395-07:00I have not installed default 4.17.5, but if I'...I have not installed default 4.17.5, but if I'll remember, I'll do that at home in coming days.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2963790426029213933.post-16960010406760967642018-07-10T12:40:42.647-07:002018-07-10T12:40:42.647-07:00How is it compared to stock kernel (no PDS, no MUX...How is it compared to stock kernel (no PDS, no MUX)?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2963790426029213933.post-89898350178315831802018-07-10T10:57:45.318-07:002018-07-10T10:57:45.318-07:00Boots ok here, on Ryzen 1700 and Ryzen 2400G (kid ...Boots ok here, on Ryzen 1700 and Ryzen 2400G (kid got a new computer :)) Will try on i7@work as well.<br />Since I'm a crazy person, I'll try full tickless system with 0.98s, will report back with some feeling and/or numbers about system behavior.<br />First results for 0.98s + nohz_full are as follows (took results from previous tests as well):<br />D3 location 1: PDS (105 FPS), PDS+nohz_full (115 FPS), MUX+MC (110 FPS), MUX+SMT (55 FPS)<br />D3 location 2: PDS (67 FPS), PDS+nohz_full (68 FPS), MUX+MC (70 FPS), MUX+SMT (40 FPS)<br />POE location 1: PDS (120 FPS), PDS+nohz_full (130 FPS), MUX+MC (120 FPS), MUX+SMT (120 FPS)<br /><br />Please take into consideration that latest nohz_full build is 4.17.5 while previous are 4.17.2, dunno if that does make a diff.<br /><br />Thanks Alfred.<br /><br />BR, EduardoAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2963790426029213933.post-87791670808912641172018-07-09T14:14:45.128-07:002018-07-09T14:14:45.128-07:00Builds/boots fine for me.
