* cbmem: Break out CBMEM_ID to a separate header fileMarc Jones2015-06-091-1/+1
| | | | | | | | | | | | | | The cbmem util needs the CBMEM_IDs and the strings for reporting and shares the cbmem.h file with coreboot. Split out the IDs so for a simpler sharing and no worries about overlap of standard libraries and other things in the header that coreboot requires, but the tool does not.

* Remove address from GPLv2 headersPatrick Georgi2015-05-212-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By design, the imd library still provdes dynamic growth so that feature is consistent.

* timestamps: You can never have enough of them!Julius Werner2015-04-141-22/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* cbmem: stop assuming 1MiB of memory can be mappedAaron Durbin2015-03-211-20/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default mapping size is 1MiB of ram. However, not all systems allow 1MiB of memory to mapped depending on the kernel's memory map. Therefore, be explicit about the sizes to mmap(). The only path that wasn't cleaned up was the coverage path as that needs to handle dynamic cbmem. The correct way to fix that is to add a global like the timestamps that is set while parsing cbtable. BUG=chrome-os-partner:31355 BRANCH=None TEST=Can cbmem -ltc on ryu.

* cbmem: Add support for new 'coreboot' compatible device tree bindingJulius Werner2015-01-131-17/+158
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch brings the cbmem utility in line with the recent change to coreboot's device tree binding. Since trying to find the right node to place this binding has been so hard (and still isn't quite agreed upon), and because it's really the more correct thing to do, this code searches through the device tree for the 'coreboot' compatible property instead of looking up a hardcoded path. It also provides bullet-proof '#address-cells' handling that should work for any endianness and size. BUG=chrome-os-partner:29311 TEST=Ran cbmem -c and cbmem -t on Nyan_Big. Also straced the to make sure everything looks as expected. 'time cbmem -t' = ~35ms shows that there is no serious performance problem from the more thorough lookup code.

* cbmem utility: compatibility with older coreboot versionsStefan Reinauer2013-11-251-2/+22
| | | | | | | | | | | | | | | | | | | | | | | Commit b8ad224 changed the memory address in lb_cbmem_ref coreboot table entries from a pointer to a uint64_t. This change was introduced to make the cbmem utility work on both 32bit and 64bit userland. Unfortunately, this broke the cbmem utility running on older versions of coreboot because they were still providing a 32bit only field for the address while the cbmem utility would now take the following 4 bytes as upper 32bits of a pointer that can obviously not be mmapped. This change checks if the size of the lb_cbmem_ref structure provided by coreboot is smaller than expected, and if so, ignore the upper 32bit of the address read.

* Implement GCC code coverage analysisStefan Reinauer2013-01-121-7/+129
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to provide some insight on what code is executed during coreboot's run time and how well our test scenarios work, this adds code coverage support to coreboot's ram stage. This should be easily adaptable for payloads, and maybe even romstage. See http://gcc.gnu.org/onlinedocs/gcc/Gcov.html for more information. To instrument coreboot, select CONFIG_COVERAGE ("Code coverage support") in Kconfig, and recompile coreboot. coreboot will then store its code coverage information into CBMEM, if possible. Then, run "cbmem -CV" as root on the target system running the instrumented coreboot binary. This will create a whole bunch of .gcda files that contain coverage information. Tar them up, copy them to your build system machine, and untar them. Then you can use your favorite coverage utility (gcov, lcov, ...) to visualize code coverage. For a sneak peak of what will expect you, please take a look at http://www.coreboot.org/~stepan/coreboot-coverage/ Change-Id: Ib287d8309878a1f5c4be770c38b1bc0bb3aa6ec7 Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/2052 Tested-by: build bot (Jenkins) Reviewed-by: David Hendricks <dhendrix@chromium.org> Reviewed-by: Martin Roth <martin@se-eng.com> Reviewed-by: Ronald G.

The util/cbmem/cbmem.py script allows to access the table after ChromeOS boots up and display its contents on the console. The problem is that shipping images do not include Python interpreter, so there is no way to access the table on a production machine. This change introduces a utility which is a Linux app displaying the timestamp table. Conceivably the output of this utility might be included in one of the ChromeOS :/system sections, so it was attempted to write this procedure 'fail safe', namely reporting errors and not continuing processing if something goes wrong. Including of coreboot/src .h files will allow to keep the firmware timestamp implementation and this utility in sync in the future. Test: . build the utility (run 'make' while in chroot in util/cbmem) . copy `cbmem' and 'cbmem.py' to the target . run both utilities (limiting cbmem.py output to 25 lines or so) . observe that the generated tables are identical (modulo rounding up of int division, resulting in 1 ns discrepancies in some cases) localhost var # ./cbmem 18 entries total: 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) localhost var # ./cbmem.py | head -25 time base 4249800, total entries 18 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) Change-Id: I013e594d4afe323106d88e7938dd40b17760621c Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: http://review.coreboot.org/1759 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
