r3211 - in trunk/payloads/coreinfo: . util/kconfig
by svn＠coreboot.org 03 Apr '08

03 Apr '08

Author: uwe Date: 2008-04-04 00:20:35 +0200 (Fri, 04 Apr 2008) New Revision: 3211 Modified: trunk/payloads/coreinfo/Makefile trunk/payloads/coreinfo/util/kconfig/conf.c trunk/payloads/coreinfo/util/kconfig/confdata.c Log: Doing another 'make' after a 'make clean' was broken until now. Fix it by not deleting build/config.h during 'make clean' (only in 'make distclean'). Also, change the default behaviour of 'make' from asking the user to run 'make config' (or similar) to actually _run_ 'make config' without asking questions. It's always possible to explicitly invoke 'make menuconfig' or 'make xconfig' and so on, of course. Finally, make _all_ targets (allyesconfig, randconfig, and so on) generate a build/config.h file, as we always #include it.

Summit recordings/live stream
by Carl-Daniel Hailfinger 03 Apr '08

03 Apr '08

Hi, could someone please record the various talks at the summit, preferably both video and audio. Having audio available would help immensely even if no video is provided. In case nobody has equipment for that, any standard headset for VoIP calls has a pretty decent microphone which can be used to record audio with a laptop. One hour of 44 kHz, 16bit mono recording needs ~300 MB as uncompressed Wave file. Regards, Carl-Daniel

Compile error in coreboot-v2: "failed to trunc value: mask ff"
by Corey Osgood 02 Apr '08

02 Apr '08

Working with romcc here, you can drop this block of code into the auto.c/raminit portion of any board using romcc and reproduce the error (it compiles fine with CAR, but that's not an option with the c7 cpu, at least not yet): u8 reg8, spd_data; reg8 = pci_read_config8(PCI_DEV(0, 0, 3), 0x62); spd_data = smbus_read_byte(0x50, 30); spd_data = spd_data / 10; if(spd_data < 5) spd_data = 5; else if(spd_data > 20) spd_data = 20; if(spd_data > (reg8 >> 4)) { reg8 &= 0xf; reg8 |= (spd_data << 4); } The error is confirmed on ubuntu 8.04 alpha/beta/? and debian unstable, both with gcc 4.2.3, and also gentoo with gcc 4.1.2: dst type: auto unsigned char dst: %edx:%eax auto.c:35.1: raminit.c:436.33: raminit.c:615.36: auto.c:218.32: 0x83cbe70 convert Internal compiler error: failed to trunc value: mask ff make[1]: *** [auto.inc] Aborted (core dumped) Commenting out either spd_data/10 or the if/else portion gets rid of the error, it only happens when all of these statements are in. I also have half a dozen blocks like this which compile fine: reg8 = pci_read_config8(ctrl->d0f3, 0x63); j = spd_read_byte(ctrl->channel0[i], SPD_tRRD);//ctrl->channel0[0] = 0x50 spd_data = ((j >> 2) * 100); spd_data |= ((j & 0x3) * 25); spd_data = spd_data / (ram_cycle * 100); //ram_cycle in this case = 10 if(spd_data < 2) spd_data = 2; else if(spd_data > 5) spd_data = 5; if((spd_data - 2) > (reg8 >> 6)) { reg8 &= 0x3f; reg8 |= (spd_data - 2) << 6; } It's just that one instance that fails to compile. I've tried moving it around, changing the variables, changing the types, modifying the math, etc, etc, and nothing seems to help. Any suggestions?

lzma v3 fails to compile under gcc-4.3.x
by Devils-Hawk 02 Apr '08

02 Apr '08

compiling with gcc-4.3.0 will result in the following or similar: > error: 'memcpy' is not a member of 'std' because gcc-4.3.0 does not include certain standard C-headers in C++ programs by default anymore. Attached simple stupid patch should fix that. regards, devh

Re: [coreboot] #76: coreboot messages should be accessible in dmesg

#76: coreboot messages should be accessible in dmesg ----------------------------+----------------------------------------------- Reporter: stepan | Owner: rminnich Type: enhancement | Status: new Priority: major | Milestone: Setting up LinuxBIOS v3 Component: coreboot | Version: v3 Resolution: | Keywords: Dependencies: | Patchstatus: there is no patch ----------------------------+----------------------------------------------- Changes (by uwe): * summary: LinuxBIOS messages should be accessible in dmesg => coreboot messages should be accessible in dmesg Comment: FYI, I'll add a coreinfo module which can display (and scroll through) the coreboot "dmesg buffer" as part of GSoC (if I'll get accepted). Actually, that code is pretty much finished already and works quite nicely (hardcodes the buffer address in RAM though). Will post a patch when GSoC officially started. I haven't done any work on using it from _Linux_, though. -- Ticket URL: <http://tracker.coreboot.org/trac/coreboot/ticket/76#comment:4> coreboot <http://www.coreboot.org/>
