New patch to review for coreboot: 7b1da0f Make libpayload parse the coreboot tables before setting up the consoles

If that structure hasn't been populated, the driver decides that there is no framebuffer and disables itself. Reversing the order these are set up fixes that problem.

New patch to review for coreboot: 051b64d Force coreboot mconf to create temp files in the output directory
by Stefan Reinauer 30 Mar '12

30 Mar '12

Stefan Reinauer (stefan.reinauer(a)coreboot.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/815 -gerrit commit 051b64d6dda2a829454e5df752134dcbb0a35ba1 Author: Vadim Bendebury <vbendeb(a)chromium.org> Date: Mon Oct 24 14:06:23 2011 -0700 Force coreboot mconf to create temp files in the output directory This change partially addresses the problem with attempting to generate coreboot image out of tree. The configuration step fails when in cheroot, if the destination directory is placed in /tmp. The problem is that the mconf package tries renaming the temporary file created in the local directory into the destination config file. If the destination root and the local directory are located on different file systems, the rename operation fails. The proper fix (still upcoming) would be to identify all places where mconf creates temp files, and make sure that all temp files get created in the destination tree. This change modifies just one location, which prevents building out of tree in the most common case. Test: run the following in the coreboot directory in chroot: (coreboot) cp config.lumpy .config (coreboot) /bin/rm -rf /tmp/cb (coreboot) CROSS_COMPILE=i686-pc-linux-gnu- make obj=/tmp/cb oldconfig (coreboot) CROSS_COMPILE=i686-pc-linux-gnu- make obj=/tmp/cb Observe the build succeed (it was failing during the config phase before this change) Change-Id: If4506e984b8afc192a1689c7b0aa956dd35f66c6 Signed-off-by: Vadim Bendebury <vbendeb(a)chromium.org> --- util/kconfig/confdata.c | 53 ++++++++++++++++++++++++++++++++++++++-------- 1 files changed, 43 insertions(+), 10 deletions(-) diff --git a/util/kconfig/confdata.c b/util/kconfig/confdata.c index 79e0b35..df39fcc 100644 --- a/util/kconfig/confdata.c +++ b/util/kconfig/confdata.c @@ -674,6 +674,33 @@ out: return res; } +/* + * Return malloced string the contents of which are a concatenation of the + * directory name of the first argument and the second argument. + */ +static char* get_tmp_file_name(const char* base, const char *tmp_name) +{ + char *file_name, *p; + /* for sure a few bytes longer than needed */ + int file_name_size = strlen(base) + sizeof(file_name) + 10; + + file_name = malloc(file_name_size); + if (!file_name) { + fprintf(stderr, "%s:%d: failed to allocate %d bytes\n", + __FILE__, __LINE__, file_name_size); + return 0; + } + + strcpy(file_name, base); + p = strrchr(file_name, '/'); + if (p) + strcpy(p + 1, tmp_name); + else + strcpy(file_name, tmp_name); + + return file_name; +} + int conf_write_autoconf(void) { struct symbol *sym; @@ -682,10 +709,19 @@ int conf_write_autoconf(void) FILE *out, *out_h; time_t now; int i, l; - char tmpname[128], tmpname_h[128]; + char *tmp_conf, *tmp_conf_h; sym_clear_all_valid(); + name = getenv("KCONFIG_AUTOHEADER"); + if (!name) + name = "include/linux/autoconf.h"; + + tmp_conf = get_tmp_file_name(name, ".tmpconfig"); + tmp_conf_h = get_tmp_file_name(name, ".tmpconfig.h"); + if (!tmp_conf || !tmp_conf_h) + return 1; + file_write_dep("build/auto.conf.cmd"); #if 0 @@ -693,13 +729,11 @@ int conf_write_autoconf(void) return 1; #endif - sprintf(tmpname, ".tmpconfig.%d", (int)getpid()); - out = fopen(tmpname, "w"); + out = fopen(tmp_conf, "w"); if (!out) return 1; - sprintf(tmpname_h, ".tmpconfig.h.%d", (int)getpid()); - out_h = fopen(tmpname_h, "w"); + out_h = fopen(tmp_conf_h, "w"); if (!out_h) { fclose(out); return 1; @@ -790,11 +824,8 @@ int conf_write_autoconf(void) fclose(out); fclose(out_h); - name = getenv("KCONFIG_AUTOHEADER"); - if (!name) - name = "include/linux/autoconf.h"; UNLINK_IF_NECESSARY(name); - if (rename(tmpname_h, name)) + if (rename(tmp_conf_h, name)) return 1; name = getenv("KCONFIG_AUTOCONFIG"); if (!name) @@ -804,9 +835,11 @@ int conf_write_autoconf(void) * and this marks the successful completion of the previous steps. */ UNLINK_IF_NECESSARY(name); - if (rename(tmpname, name)) + if (rename(tmp_conf, name)) return 1; + free(tmp_conf_h); + free(tmp_conf); return 0; }

separate mailling list for gerrit mails?
by Patrick Georgi 30 Mar '12

30 Mar '12

Hi, this came up on IRC again, but I think the issue requires wider discussion: Several people asked if gerrit mails can be moved to a separate mailing list to reduce the "mechanic" noise. We're highly flexible there, so we can keep it like it is, reduce the number of mail types, send different types to different lists, ... One proposal was to move all gerrit mail to coreboot-gerrit@ or so. A variant of that could be to move all gerrit mail to coreboot-gerrit@ except for the "change merged to master" mails, so people have an easier overview on what happens in our main branch. So asking generally: Do you like it the way it is, or do you think it should change, and how? Patrick

hi everyone, I want to buile a release coreboot , in other words, I don't want my coreboot to print any boot messages when booting. I did not find any options in the "menuconfig menu". Thanks a lot. BRs, Rock Cui
