by gerrit＠coreboot.org June 30, 2015

June 30, 2015

the following patch was just integrated into master: commit 04fb7a81c1a08e3f4276dcdc489ea51238d36b2b Author: Stefan Reinauer <stefan.reinauer(a)coreboot.org> Date: Mon Jun 29 16:08:39 2015 -0700 coreinfo: Use IS_ENABLED() to query Kconfig variables This will make the code work with the different styles of Kconfig (emit unset bools vs don't emit unset bools) Roughly, the patch does this, and a little bit of fixing up: perl -pi -e 's,ifdef (CONFIG_.+?)\b,if IS_ENABLED$$1$,g' `find . -name *.[ch]` perl -pi -e 's,ifndef (CONFIG_.+?)\b,if !IS_ENABLED$$1$,g' `find . -name *.[ch]` Change-Id: Ia461a33541f58ff39e984119c44ece7e6c05608a Signed-off-by: Stefan Reinauer <stefan.reinauer(a)coreboot.org> Reviewed-on: http://review.coreboot.org/10713 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <pgeorgi(a)google.com> See http://review.coreboot.org/10713 for details. -gerrit

In order to make the +timestamps persistent and accessible from the kernel, we need to ensure that all +the saved timestamps end up in cbmem area under the CBMEM_ID_TIMESTAMP +tag. However, until the cbmem area is available, the timestamps can be saved to +board/SOC-defined _timestamp region or in a local stage-specific stash. The work +of identifying the right location for storing timestamps is done by the library +and is not exposed to the user. + + Working of timestamp library from a user perspective can be outlined in +the following steps: +1. Initialize the _timestamp cache (if any used) +2. Initialize the base time and reset cbmem timestamp area +3. Start adding timestamps + + Steps 1) and 2) above can be performed in a single API call as explained +in later sections. Behind the scenes, the timestamp library takes care of: +1. Identifying the correct location for storing timestamps (cbmem or _timestamp +region or local stash). +2. Once cbmem is up, ensure that all timestamps are synced from _timestamp +region or local stash into the cbmem area. +3. Add a new cbmem timestamp area based on whether a reset of cbmem timestamp +region is required / not. + +========================== Data structures used ================================ + + The main structure that maintains information about the timestamp cache +is: +struct __attribute__((__packed__)) timestamp_cache { + uint16_t cache_state; + uint16_t cbmem_state; + struct timestamp_table table; + struct timestamp_entry entries[MAX_TIMESTAMP_CACHE]; +}; + +1. cache_state + The state of the cache is maintained by cache_state attribute which can +be any one of the following: + +enum { + TIMESTAMP_CACHE_UNINITIALIZED = 0, + TIMESTAMP_CACHE_INITIALIZED, + TIMESTAMP_CACHE_NOT_NEEDED, +}; + + By default, if the cache is stored in local stash (bss area), then it +will be reset to uninitialized state. However, if the cache is stored in +_timestamp region, then it might have garbage in any of the attributes. Thus, if +_timestamp region is being used by any board, it is important to call +timestamp_early_init which provides the initialization of timestamp cache. + + Once the cache is initialized, its state is set to +cache_initialized. Henceforth, the calls to cache i.e. timestamp_add know that +the state reflected is valid and timestamps can be directly saved in the cache. + + When cbmem area is up (i.e. call to cbmem_initialize), we do not need to +store the timestamps in local stash / _timestamp area anymore. Thus, the cache +state is set to cache_not_needed, which allows timestamp_add to store all +timestamps directly into cbmem area. + + +2. cbmem_state + This attribute indicates if we need to reset the timestamp area in +cbmem. This needs to be done for fresh boot (when there is no timestamp area +allocated in cbmem) or during resume (to clean out timestamps from earlier +boot). This can be set to any one of the following values: + +enum { + TIMESTAMP_CBMEM_RESET_NOT_REQD = 0, + TIMESTAMP_CBMEM_RESET_REQD, +}; + + If _timestamp region is being used, the call to timestamp_early_init +sets this field to reset_reqd. If this region is not being used, then instead +the call to timestamp_init sets this field to reset_reqd. Thus, when cbmem +initialization is complete, the timestamp library ensures that the cbmem +timestamp area is properly set as per the value of this attribute and resets +this field to reset_not_reqd. In case of resume path, this field would be set +accordingly by timestamp_early_init / timestamp_init thus ensuring that +timestamps from earlier boot dont float around into current boot logs. Also, +during early ramstage, when cbmem is not yet up, local stash would be used which +is in the bss area and thus this field is set to reset_not_reqd (unless +timestamp_init is called before or after cbmem_intiialize). Hence, when ramstage +brings up cbmem and syncs timestamps, the cbmem timestamp area is not reset. If +ramstage is the first stage where timestamp_init is called, then the cbmem area +is accordingly reset in timestamp_sync or timestamp_init based on the order in +which calls are made. Details are explained in the use cases towards the end. + + +3. table + This field is represented by a structure which provides overall +information about the entries in the timestamp area: + +struct timestamp_table { + uint64_t base_time; + uint32_t max_entries; + uint32_t num_entries; + struct timestamp_entry entries[0]; /* Variable number of entries */ +} __attribute__((packed)); + + It indicates the base time for all timestamp entries, maximum number of +entries that can be stored, total number of entries that currently exist and an +entry structure to hold variable number of entries. + + +4. entries + This field holds the details of each timestamp entry, upto a maximum of +MAX_TIMESTAMP_CACHE which is defined as 16 entries. Each entry is defined by: + +struct timestamp_entry { + uint32_t entry_id; + uint64_t entry_stamp; +} __attribute__((packed)); + + entry_id holds the timestamp id corresponding to this entry and +entry_stamp holds the actual timestamp. + + + For timestamps stored in the cbmem area, a timestamp_table is allocated +with space for MAX_TIMESTAMPS equal to 30. Thus, the cbmem area holds base_time, +max_entries (which is 30), current number of entries and the actual entries +represented by timestamp_entry. + + +========================== Internal Functions ================================== + +1. timestamp_cache_init + Initializes the timestamp cache to a known state by setting num_entries +to 0, base_entries to MAX_TIMESTAMP_CACHE, base_time to caller-provided base, +cache_state to TIMESTAMP_CACHE_INITIALIZED and cbmem_state to caller-provided +state. + + +2. timestamp_cache_get + This function returns a pointer to timestamp cache. It basically +identifies what cache to use based on following parameters: +a. If __PRE_RAM__ is true i.e. we are in pre-ramstage step and _timestamp region +is provided, use _timestamp region. +b. Otherwise use local stash + + If using _timestamp region, it ensures that the size of the region is +big enough to hold all of timestamp_cache structure and MAX_TIMESTAMP_CACHE +timestamp entries. Once the location of cache is decided, it checks to see if +cache is not yet initialized, and calls timestamp_cache_init if required. + + +3. timestamp_alloc_cbmem_table + This function exists only in romstage and ramstage since only these two +stages access cbmem area. It allocates a new table for MAX_TIMESTAMPS number of +entries in the cbmem area using CBMEM_ID_TIMESTAMP tag. It also resets the +base_time and num_entries to 0. + + +4. timestamp_table_get + This function returns a pointer to the timestamp table. Based on the +value of cache_state in timestamp_cache, it provides a pointer either to the +cache (in stash or _timestamp region) or the cbmem timestamp table. If a pointer +to the cbmem timestamp table is returned, it checks to see if cbmem_state +indicates a reset of the cbmem timestamp area. If required, it makes a call to +timestamp_alloc_cbmem_table. + + +5. timestamp_add_table_entry + This function adds a new entry to the timestamp table obtained by making +a call to timestamp_table_get. It sets the id based on user-provided id and the +stamp is set to user-provided time - table base time. This is to normalize all +the timestamps. + + +============================= Function APIs ==================================== + +1. timestamp_early_init + It is essential to call this function only if _timestamp region is being +used. This should be the first call made to the timestamp library. Since +_timestamp region can contain arbitary values in the different fields of the +cache, this function initializes the fields properly by calling +timestamp_cache_init with the cache pointer, user-provided base time and +cbmem_state as TIMESTAMP_CBMEM_RESET_REQD. This will provide an indication that +cbmem timestamp area needs to be added (in case of fresh boot) or reset to 0 +entries(in case of resume). + + +2. timestamp_init + It is essential to call this function before any call to timestamp_add +is made. In case of _timestamp region being used, only a call to +timestamp_early_init is required. In all other cases, it is essential to call +timestamp_init to set the cbmem_state to TIMESTAMP_CBMEM_RESET_REQD. This will +provide an indication that cbmem timestamp area needs to be added (in case of +fresh boot) or reset to 0 entries(in case of resume). + + +3. timestamp_add + This function accepts from user a timestamp id and time to record in the +timestamp table. Based on the table provided by timestamp_table_get, it stores +the entry in the appropriate table in cbmem or _timestamp region or local +stash. + + +4. timestamp_add_now + This function calls timestamp_add with user-provided id and current +time. + + +5. timestamp_sync + This is one of the most important functions required to ensure the +proper functioning of the timestamp library across cbmem, _timestamp region and +local stash with minimal interference for the user. It is important to note that +this function is called only by cbmem_initialize to ensure that once the cbmem +area is ready, we automatically sync all the timestamps saved in the cache to +cbmem area. Thus, the user never has to call the timestamp_sync function. + + This function checks to see if the cache state indicates that a cbmem +reset of timestamp area is required or no timestamp area exists in cbmem at +all. In that case, it allocates a new cbmem area by calling +timestamp_alloc_cbmem_table. + + Otherwise, it uses cbmem_find to use the timestamp area in cbmem. It +then uses timestamp_add_table_entry to move all the entries from cache to cbmem +area. Here, two cases can occur with respect to the base time subtraction: + +a. Newly added cbmem table will have a base time of 0. Thus, no adjustments are +required for the timestamps being added from cache to cbmem table. + +b. Timestamps added to cache before ramstage: In this case, the base time in +cache table will be 0 and timestamp_add_table_entry will take care of +subtracting the correct base_time. Finally, it resets the timestamp cache to: + + cache_state: TIMESTAMP_CACHE_NOT_NEEDED + cbmem_state: TIMESTAMP_CBMEM_RESET_NOT_REQD + num_entries: 0 + + Also, the base_time in cbmem table is update if it is currently zero +indicating that it needs to inherit base time from cache table since +cbmem table might be newly allocated. + + +============================= Use / Test Cases ================================= + + The following cases have been considered while designing the timestamp +library. It is important to ensure that any changes made to this library satisfy +each of the following use cases: + +Case 1: Timestamp Region Exists (Fresh Boot / Resume) + + +1. timestamp_early_init is called to setup the cache state and cbmem_state is +set to reset_reqd. These properties are set in the timestamp cache which is part +of _timestamp region. + +2. <Any number of timestamp_add / timestamp_add_now> : All saved in _timestamp +region + +3. Once cbmem_initiliaze is complete, it calls timestamp_sync, which checks the +_timestamp region to check the cbmem_state field. Since it says reset_reqd, a +new area for timestamp is setup in cbmem by calling cbmem_add. The value of +cbmem_state is set to reset_not_reqd in _timestamp region cache. + +4. After entering ramstage, the local stash acts as the timestamp cache. Since +it is in BSS area, the cache_state field is set to uninitialized and cbmem_state +field is set to reset_not_reqd. + +5. On any call to timestamp_add / timestamp_add_now, it initializes the cache +and sets cache_state field to initialized whereas cbmem_state is still set to +reset_not_reqd. + +6. Once cbmem_initiliaze is complete, it calls timestamp_sync, which checks the +local stash to check the cbmem_state field. Since it says reset_not_reqd, it +uses cbmem_find to find already allocated timestamp area in cbmem. If none is +found, it allocates a new one. + +7. <Any number of calls to timestamp_add / timestamp_add_now> : All saved in +cbmem + + +Case 2: No timestamp region, fresh boot, cbmem_initialize called after +timestamp_init + +1. Since timestamp_init is called before cbmem_initialize, it will set the cache +field attributes to: cache_state as initialized and cbmem_state as +reset_reqd. This ensures that timestamp_sync sets up a new cbmem area for +timestamps. + +2. < Any number of calls to timestamp_add / timestamp_add_now> : All saved in +stash + +3. Once cbmem_initiliaze is complete, it calls timestamp_sync, which checks the +stash cache to check the cbmem_state field. Since it says reset_reqd, a new area +for timestamp is setup in cbmem by calling cbmem_add. The value of cbmem_state +is set to reset_not_reqd in stash cache. + +4. After entering ramstage, a new local stash acts as the timestamp cache. Since +it is in BSS area, the cache_state field is set to uninitialized and cbmem_state +field is set to reset_not_reqd. + +5. On any call to timestamp_add / timestamp_add_now, it initializes the cache +and sets cache_state field to initialized whereas cbmem_state is still set to +reset_not_reqd. + +6. Once cbmem_initiliaze is complete, it calls timestamp_sync, which checks the +local stash to check the cbmem_state field. Since it says reset_not_reqd, it +uses cbmem_find to find already allocated timestamp area in cbmem. If none is +found, it allocates a new one. + +7. <Any number of calls to timestamp_add / timestamp_add_now> : All saved in +cbmem + + +Case 3: No timestamp region, fresh boot, cbmem_initialize called before +timestamp_init + +1. Since cbmem_initialize is called before timestamp_init, it will call +timestamp_sync which checks local stash to check for cbmem_state field. Since, +cbmem_state says no_reset_reqd, it uses cbmem_find to look for a timestamp area +in cbmem. Since, it is a fresh boot, none will be found and it uses cbmem_add to +create a new area on cbmem. + +2. timestamp_init is called, which sets local cache state to reset required. It +then calls timestamp_table_get which sees that cache_state is cache_not_needed +and cbmem_state is reset_reqd. Thus, it calls timestamp_alloc_cbmem_table to +reset the cbmem area which is as good as no change in the state of cbmem +area. Then, the cbmem_state is set to reset_not_reqd. + +3. <Any number of calls to timestamp_add / timestamp_add_now> : All saved in +cbmem + +4. After entering ramstage, a new local stash acts as the timestamp cache. Since +it is in BSS area, the cache_state field is set to uninitialized and cbmem_state +field is set to reset_not_reqd. + +5. On any call to timestamp_add / timestamp_add_now, it initializes the cache +and sets cache_state field to initialized whereas cbmem_state is still set to +reset_not_reqd. + +6. Once cbmem_initiliaze is complete, it calls timestamp_sync, which checks the +local stash to check the cbmem_state field. Since it says reset_not_reqd, it +uses cbmem_find to find already allocated timestamp area in cbmem. If none is +found, it allocates a new one. + +7. <Any number of calls to timestamp_add / timestamp_add_now> : All saved in +cbmem + + +Case 4: No timestamp region, resume, cbmem_initialize called after +timestamp_init + +1. Since timestamp_init is called before cbmem_initialize, it will set the cache +field attributes to: cache_state as initialized and cbmem_state as reset_reqd. + +2. < Any number of calls to timestamp_add / timestamp_add_now> : All saved in +stash + +3. Once cbmem_initiliaze is complete, it calls timestamp_sync, which checks the +stash cache to check the cbmem_state field. Since it says reset_reqd, +timestamp_sync resets cbmem area to num_entries=0, thus flushing timestamps from +earlier boot. The value of cbmem_state is set to reset_not_reqd in stash cache. + +4. After entering ramstage, a new local stash acts as the timestamp cache. Since +it is in BSS area, the cache_state field is set to uninitialized and cbmem_state +field is set to reset_not_reqd. + +5. On any call to timestamp_add / timestamp_add_now, it initializes the cache +and sets cache_state field to initialized whereas cbmem_state is still set to +reset_not_reqd. + +6.

Since cbmem_initialize is called before timestamp_init, it will call +timestamp_sync which checks local stash to check for cbmem_state field. Since, +cbmem_state says no_reset_reqd, it uses cbmem_find to look for a timestamp area +in cbmem. Since, it is resume, it will find the older cbmem timestamp area from +earlier boot. However, nothing is added to cbmem area since timestamp_add / +timestamp_add_now is expected to be used only after call to timestamp_init. + +2. timestamp_init is called, which sets local cache state to reset required. It +then calls timestamp_table_get which sees that cache_state is cache_not_needed +and cbmem_state is reset_reqd. Thus, it calls timestamp_alloc_cbmem_table to +reset the cbmem area which sets num_entries to 0. Thus, flushing timestamps from +earlier boot.
