2015-05-26timestamp: Fix collection without EARLY_CBMEM_INITKyösti Mälkki
With LATE_CBMEM_INIT, do not search for the initial collection from CBMEM in ramstage. On S3 resume this would find the non-empty collection from previous run of ramstage. Start with an empty table instead. Remove a spurious error message as the stamps get stashed and will be copied to CBMEM later.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>
2015-05-07timestamp: fix incremental linking error for !HAVE_MONOTONIC_TIMERAaron Durbin
In linking ramstage a single object file is created before linking with the linker script. Though there is a weak timestamp_get() symbol in timestamp.c any of its dependent symbols need to be available during the incremental link. As not all platforms have HAVE_MONOTONIC_TIMER enabled this will create a linking error. Fix this by providing a hint to the compiler to remove dead code and thus the dependent symbols causing linking errors in the presence of !HAVE_MONOTONIC_TIMER.

2015-04-14timestamps: You can never have enough of them!Julius Werner
Now that we have timestamps in pre-RAM stages, let's actually make use of them. This patch adds several timestamps to both the bootblock and especially the verstage to allow more fine-grained boot time tracking. Some of the introduced timestamps can appear more than once per boot. This doesn't seem to be a problem for both coreboot and the cbmem utility, and the context makes it clear which operation was timestamped at what point. Also simplifies cbmem's timestamp printing routine a bit, fixing a display bug when a timestamp had a section of exactly ",000," in it (e.g. 1,000,185). BRANCH=None BUG=None TEST=Booted Pinky, Blaze and Falco, confirmed that all timestamps show up and contained sane values. Booted Storm (no timestamps here since it doesn't support pre-RAM timestamps yet).

2012-11-13Add method for delaying adding of timestampsStefan Reinauer
In hardwaremain() we can't add timestamps before we actually reinitialized the cbmem area. Hence we kept the timestamps in an array and added them later. This is ugly and intrusive and helped hiding a bug that prevented any timestamps to be logged in hardwaremain() when coming out of an S3 resume. The problem is solved by moving the logic to keep a few timestamps around into the timestamp code. This also gets rid of a lot of ugly ifdefs in hardwaremain.c Change-Id: I945fc4c77e990f620c18cbd054ccd87e746706ef Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/1785 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-03-28Add timestamp collecting to coreboot.Vadim Bendebury
This patch adds code to initialize the time stamp collection facility in coreboot. It adds a table in the CBMEM section, which provides the base timer reading value (all other readings are offsets of this one) and an array of timestamp id/timestamp value pairs. Just two values are being added now, this will have to be used more extensively and also integrated into payloads to provide more comprehensive boot process time measurements. Also, since the CBMEM area could already contain a section (from the previous run, before reset), when processing a section addition request we should check if a section already exists and return its address, if so.
