2019-11-03boot_state: Reduce precision of reported timesKyösti Mälkki
When diffing boot logs, lines reporting times spent in each boot_state always get highlighed due the little fluctuation in microsecond-scale. Reduce the logged precision to milliseconds to avoid that.

2019-09-11timestamps: Improve collection for ENV_ROMSTAGE_OR_BEFOREKyösti Mälkki
Keep track of the active timestamp table location using a CAR_GLOBAL variable. Done this way, the entire table can be located outside _car_relocatable_data and we only switch the pointer to CBMEM and copy the data before CAR gets torn down. Fix comments about requirements of timestamp_init() usage. Remove timestamp_cache from postcar and ramstage, as CBMEM is available early on.

2016-12-08bootstate: add arch specific hook at coreboot exitAaron Durbin
The bootstate machine allows one to schedule work at the boundaries of each state. However, there are no priorities by design. As such if there are things that need to be performed that are interdependent between callbacks there's no way to do that aside from explicitly putting the call in one of the callbacks. This situation arises around BS_OS_RESUME, BS_PAYLOAD_LOAD, and BS_PAYLOAD_BOOT as those are the states where coreboot is about to exit. As such, provide an architecture specific hook at these key places so that one is guaranteed any work done in arch_bootstate_coreboot_exit() is after all callbacks in the state machine.

The 8250 MMIO uart driver calls udelay, and if that is the first call then it will also call printk in init_timer() which can result in a deadlock trying to acquire the console lock. There are a few options to prevent this: 1) remove the printk in init_timer which removes a useful debug message 2) change the udelay() to cpu_relax() in uart8250mem.c 3- move the init_timer() call in ramstage main() to be called earlier Since hardwaremain.c:main() already has an explicit call to init_timer() on x86 it is an easy change to move this to happen before the console is initialized.

2015-06-02cbfs: new API and better program loadingAaron Durbin
A new CBFS API is introduced to allow making CBFS access easier for providing multiple CBFS sources. That is achieved by decoupling the cbfs source from a CBFS file. A CBFS source is described by a descriptor. It contains the necessary properties for walking a CBFS to locate a file. The CBFS file is then decoupled from the CBFS descriptor in that it's no longer needed to access the contents of the file. All of this is accomplished using the regions infrastructure by repsenting CBFS sources and files as region_devices. Because region_devices can be chained together forming subregions this allows one to decouple a CBFS source from a file. This also allows one to provide CBFS files that came from other sources for payload and/or stage loading. The program loading takes advantage of those very properties by allowing multiple sources for locating a program. Because of this we can reduce the overhead of loading programs because it's all done in the common code paths. Only locating the program is per source.

2015-04-14timer: Reestablish init_timer(), consolidate timer initialization callsJulius Werner
We have known for a while that the old x86 model of calling init_timer() in ramstage doesn't make sense on other archs (and is questionable in general), and finally removed it with CL:219719. However, now timer initialization is completely buried in the platform code, and it's hard to ensure it is done in time to set up timestamps. For three out of four non-x86 SoC vendors we have brought up for now, the timers need some kind of SoC-specific initialization. This patch reintroduces init_timer() as a weak function that can be overridden by platform code. The call in ramstage is restricted to x86 (and should probably eventually be removed from there as well), and other archs should call them at the earliest reasonable point in their bootblock. (Only changing arm for now since arm64 and mips bootblocks are still in very early state and should sync up to features in arm once their requirements are better understood.) This allows us to move timestamp_init() into arch code, so that we can rely on timestamps being available at a well-defined point and initialize our base value as early as possible. (Platforms who know that their timers start at zero can still safely call timestamp_init(0) again from platform code.) BRANCH=None BUG=None TEST=Booted Pinky, Blaze and Storm, compiled Daisy and Pit.

The GCC 4.9.2 update showed that the boot_state_init_entry structures were being padded and assumed to be aligned in to an increased size. The bootstate scheduler for static entries, boot_state_schedule_static_entries(), was then calculating the wrong values within the array. To fix this just use a pointer to the boot_state_init_entry structure that needs to be scheduled. In addition to the previous issue noted above, the .bs_init section was sitting in the read only portion of the image while the fields within it need to be writable. Also, the boot_state_schedule_static_entries() was using symbol comparison to terminate a loop which in C can lead the compiler to always evaluate the loop at least once since the language spec indicates no 2 symbols can be the same value.

2014-09-13arm: Move exception_init() close to console_init()Julius Werner
This patch adds stub implementations of exception_init() to all archs so that it can be called from src/lib/hardwaremain.c. It also moves/adds all other invocations of exception_init() (which needs to be rerun in every stage) close to console_init(), in the hopes that it will be less likely overlooked when creating future boards. Also added (an ineffective) one to the armv4 bootblock implementations for consistency and in case we want to implement it later.

2013-11-26Clean up POST codes for Boot State machineDuncan Laurie
Now that there is a clearly defined boot state machine we can add some useful post codes to indicate the current point in the state machine by having it log a post code before the execution of each state. This removes the currently defined POST codes that were used by hardwaremain in favor of a new contiguous range that are defined for each boot state. The reason for this is that the existing codes are mostly used to indicate when something is done, which is confusing for actual debug because POST code debugging relies on knowing what is about to happen (to know what may be at fault) rather than what has just finished. One additonal change is added during device init step as this step often does the bulk of the work, and frequently logs POST codes itself. Therefore in order to keep better track of what device is being initialized POST_BS_DEV_INIT is logged before each device is initialized. interrupted boot with reset button and gathered the eventlog. Mosys has been extended to decode the well-known POST codes: 26 | 2013-06-10 10:32:48 | System boot | 120 27 | 2013-06-10 10:32:48 | Last post code in previous boot | 0x75 | Device Initialize 28 | 2013-06-10 10:32:48 | Extra info from previous boot | PCI | 00:16.0 29 | 2013-06-10 10:32:48 | Reset Button 30 | 2013-06-10 10:32:48 | System Reset Change-Id: Ida1e1129d274d28cbe8e49e4a01483e335a03d96 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/58106 Reviewed-on: http://review.coreboot.org/4231 Tested-by: build bot (Jenkins) Reviewed-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>
2013-11-08Add new finalize functions for devices and chipsMarc Jones
Many chipset devices require additional configuration after device init. It is not uncommmon for a device early in the devicetree list to need to change a setting after a device later in the tree does PCI init. A final function call has been added to device ops to handle this case. It is called prior to coreboot table setup. Another problem that is often seen is that the chipset or mainboard need to do some final cleanup just before loading the OS. The chip finalize has been added for this case. It is call after all coreboot tables are setup and the payload is ready to be called. Similar functionality could be implemented with the hardwaremain states, but those don't fit well in the device tree function pointer structure and should be used sparingly.

2013-05-14coreboot: add thread cooperative multitaskingAaron Durbin
The cooperative multitasking support allows the boot state machine to be ran cooperatively with other threads of work. The main thread still continues to run the boot state machine (src/lib/hardwaremain.c). All callbacks from the state machine are still ran synchronously from within the main thread's context. Without any other code added the only change to the boot sequence when cooperative multitasking is enabled is the queueing of an idlle thread. The idle thread is responsible for ensuring progress is made by calling timer callbacks. The main thread can yield to any other threads in the system. That means that anyone that spins up a thread must ensure no shared resources are used from 2 or more execution contexts. The support is originally intentioned to allow for long work itesm with busy loops to occur in parallel during a boot. Note that the intention on when to yield a thread will be on calls to udelay().

2013-05-07boot state: add ability to block state transitionsAaron Durbin
In order to properly sequence the boot state machine it's important that outside code can block the transition from one state to the next. When timers are not involved there's no reason for any of the existing code to block a state transition. However, if there is a timer callback that needs to complete by a certain point in the boot sequence it is necessary to place a block for the given state. To that end, 4 new functions are added to provide the API for blocking a state. 1. boot_state_block(boot_state_t state, boot_state_sequence_t seq); 2. boot_state_unblock(boot_state_t state, boot_state_sequence_t seq); 3. boot_state_current_block(void); 4. boot_state_current_unblock(void); Change-Id: Ieb37050ff652fd85a6b1e0e2f81a1a2807bab8e0 Signed-off-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/3204 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
