coreboot 4.4 testing / boot time regression on google/panther
by Matt DeVillier April 18, 2016

April 18, 2016

Greetings, prompted by another posting on the topic, I also noticed a significant degradation in boot time on google/panther (Asus Chromebox / Haswell mobile) . I haven't had a chance to bisect commits yet, but did test a few older firmware builds to confirm my suspicion. Below are cbmem timestamps from current ToT (2016-04-17) as well as one of my older builds (2015-10-15). I don't recall any config changes between the two, but will extract the configs to compare shortly - I just wanted to get this email out before it slipped my mind (again) cheers, Matt 2016-04-17: 20 entries total: 0:1st timestamp 9,347 1:start of rom stage 90,188 (80,840) 2:before ram initialization 114,963 (24,774) 3:after ram initialization 310,446 (195,482) 4:end of romstage 370,484 (60,038) 8:starting to load ramstage 384,426 (13,941) 15:starting LZMA decompress (ignore for x86) 390,377 (5,951) 16:finished LZMA decompress (ignore for x86) 417,628 (27,250) 9:finished loading ramstage 430,016 (12,387) 10:start of ramstage 440,820 (10,804) 30:device enumeration 446,586 (5,765) 40:device configuration 703,927 (257,340) 50:device enable 1,084,974 (381,046) 60:device initialization 1,180,544 (95,570) 70:device setup done 1,840,066 (659,522) 75:cbmem post 1,844,931 (4,864) 80:write tables 1,877,301 (32,370) 90:load payload 2,347,005 (469,704) 15:starting LZMA decompress (ignore for x86) 2,402,510 (55,504) 16:finished LZMA decompress (ignore for x86) 2,418,100 (15,589) 99:selfboot jump 2,438,022 (19,922) Total Time: 2,428,663 2015-10-15: 20 entries total: 0:1st timestamp 9,180 1:start of rom stage 103,887 (94,707) 2:before ram initialization 105,073 (1,185) 3:after ram initialization 149,422 (44,349) 4:end of romstage 152,822 (3,400) 8:starting to load ramstage 155,245 (2,423) 15:starting LZMA decompress (ignore for x86) 155,576 (330) 16:finished LZMA decompress (ignore for x86) 198,752 (43,176) 9:finished loading ramstage 200,077 (1,325) 10:start of ramstage 201,218 (1,140) 30:device enumeration 201,251 (33) 40:device configuration 205,820 (4,568) 50:device enable 207,904 (2,084) 60:device initialization 208,257 (352) 70:device setup done 231,943 (23,686) 75:cbmem post 231,956 (13) 80:write tables 236,907 (4,950) 90:load payload 240,268 (3,361) 15:starting LZMA decompress (ignore for x86) 240,436 (167) 16:finished LZMA decompress (ignore for x86) 255,986 (15,550) 99:selfboot jump 524,459 (268,473) Total Time: 515,272

Applying your three patches, indeed fix the regression in boot time by the commit 096f4579 (lib/prog_loading: introduce prog_segment_loaded()) [1]. With your patches applied it’s even faster than before. It’s now down from around 1,379 ms to 380 ms, which is even faster than the 520 ms before the regression (and 495 ms) before that. Thanks a lot! Are the patches just proof of concept, or ready to be reviewed on Gerrit? Thanks, Paul [1] https://review.coreboot.org/14214

Re: [coreboot] F2A85-M: Memory issues
by Daniel Kulesz April 18, 2016

Hi Martin, thank you for the quick reply. I just tried the memtest86 variant you suggested and it runs already for 15 minutes without reporting any errors. So the memtest86+ from the Ubuntu-Live-CD was probably a false alarm then I suppose. I didn't expect that because on a X200 with Libreboot the "regular" memtest86+ runs just fine. It would be cool if you could mention the fact about where to put the RAM already in the limitations section of the wiki page. It could save other people from flashing coreboot and being disappointed because no vga signal is there afterwards. Although one could debate whether this is a limitation or not when regarding AMD's specifications, if it was working in vendor bios most people will expect to continue working in Coreboot.

F2A85-M: Memory issues
by Daniel Kulesz April 17, 2016

April 17, 2016

Hi folks, I just flashed Coreboot 4.3 release on my F2A85-M (the "original", not Pro or whatever) together with Seabios and the VGA ROM. I am running the "bare" board with an AMD A4-5700 APU and two 8GB Corsair Sticks () at 1,5V. No attached peripherals except an usb stick which I use for booting a live system. Unfortunately, I experienced the following issues: (1) When I plug the memory sticks in the black DIMMs I get no Video, although they were working fine there before with the vendor bios. However, they "work" when inserted in the blue slots. (2) I am getting errors im memtest86+ 5.01 in compatibility mode in mem adresses around 3700M. I tried both sticks, each also in single configuration but the issue persists. I had no issues with the vendor bios (when inserted in the other slots). (3) The CPU temperature is reported wrong in Memtest86+ (Memtest86+ reports 15°C while it was around 35-40°C in the vendor bios at around the same fan speed and environment conditions). However, I don't remember if it reported a correct value with the vendor bios. The memory sticks have been reported as follows by the vendor bios: Handle 0x0035, DMI type 17, 34 bytes Memory Device Array Handle: 0x002F Error Information Handle: Not Provided Total Width: 64 bits Data Width: 64 bits Size: 4096 MB Form Factor: DIMM Set: None Locator: DIMM_B1 Bank Locator: A1_BANK2 Type: DDR3 Type Detail: Synchronous Unbuffered (Unregistered) Speed: 1333 MHz Manufacturer: Corsair Serial Number: 00000000 Asset Tag: A1_AssetTagNum2 Part Number: CMZ4GX3M1A1600C9 Rank: 2 Configured Clock Speed: 1333 MHz Are these known issues? Or maybe just a false alarm? Cheers, Daniel

Hi, I verified the mainboard Intel camelbackmountain_fsp with commit 831d65d0ba68be630e3c323e24e2be071456a9e8. I didn't see issue to boot to Fedora 21 and Windows 7, so it should be good for the upcoming release.

Re: [coreboot] On Intel Boot Guard
by Alexander Couzens April 15, 2016

April 15, 2016

Hi Iru, we aren't still sure which boards use Intel Boot Guard and which doesn't use it. But we expect most board use it, because it's "recommended" by intel - as we dont recommend it. Also there isn't yet a test script for Intel Boot Guard. Can you post a link to that forum post? I would like to look into a x240 flash image. If you have such board it would be nice if you can send me a copy of the flash image via private mail.
