missing lots of output, lack of buffer space? #1

Closed RR7 closed 9 years ago

RR7 commented 10 years ago

on the computer i'm interested in diagnosing, i seem to be missing the start of the output, it starts here in the system.log:

23/08/2014 18:46:34.000 kernel[0]: FDI_RXA_IMR................: 0x000008ff 23/08/2014 18:46:34.000 kernel[0]: FDI_RXB_IIR................: 0x00000000 23/08/2014 18:46:34.000 kernel[0]: FDI_RXB_IMR................: 0x000008ff 23/08/2014 18:46:34.000 kernel[0]: PCH_ADPA...................: 0x00c40000 (disabled, transcoder A, -hsync, -vsync) 23/08/2014 18:46:34.000 kernel[0]: HDMIB......................: 0x00000018 (disabled pipe A 8bpc SDVO DVI audio disabled +vsync +hsync non-detected) 23/08/2014 18:46:34.000 kernel[0]: HDMIC......................: 0x00000018 (disabled pipe A 8bpc SDVO DVI audio disabled +vsync +hsync non-detected) 23/08/2014 18:46:34.000 kernel[0]: HDMID......................: 0x0000001c (disabled pipe A 8bpc SDVO DVI audio disabled +vsync +hsync detected) 23/08/2014 18:46:34.000 kernel[0]: PCH_LVDS...................: 0x00000000 (disabled, pipe A, 18 bit, 1 channel)

..etc

however i can see all the MSR register info scroll past, so its like it runs out of buffer space or something.

i tested on my other computer that is also IVB but no IGPU and it logs a similar amount of data, but since there is no IGPU i can see all the MSR stuff:

..etc

the power state logs all come out fine so i guess its just in the new register dump code.

okay, i may have jumped the gun on this, i did a kextunload/kextload on it and it logged okay, i guess its just writing to the log before the log starts or something!

Piker-Alpha commented 10 years ago

I haven't done that, but I will give it a try (later today) and see what it does here.

Maybe it works when you add the msgbuf= boot argument in com.apple.Boot.plist.

I am using msgbuf=393216 (384 MB).

Piker-Alpha commented 10 years ago

No problem here with: msgbuf=393216

cool, thanks. it was also fine when i reloaded the kext, so i think it was more to do with perhaps it logging too early, MAYBE because i booted from an SSD, i'm not sure. but it seems good. i did notice on the output there ws a couple of lines saying if (devid==.... almost like it was logging the query rather than the result. i didn't see this on the linux output.

Correct. You will see some debug info, like what generation it is, to help me fix errors. Will be removed in the next update.
