2013-05-25Intel GM45, 945, SNB: Move `multiply_to_tsc()` to `tsc.h`Ronald G. Minnich
multiply_to_tsc was being copied everywhere, which is bad practice. Put it in the tsc.h include file where it belongs. Delete the copies of it. Per secunet, no copyright notice is needed. This might be a good time to get a copyright notice into tsc.h anyway. Change-Id: Ied0013ad4b1a9e5e2b330614bb867fd806f9a407 Signed-off-by: Ronald G.

2013-05-16x86: add cache-as-ram migration optionAaron Durbin
There are some boards that do a significant amount of work after cache-as-ram is torn down but before ramstage is loaded. For example, using vboot to verify the ramstage is one such operation. However, there are pieces of code that are executed that reference global variables that are linked in the cache-as-ram region. If those variables are referenced after cache-as-ram is torn down then the values observed will most likely be incorrect. Therefore provide a Kconfig option to select cache-as-ram migration to memory using cbmem. This option is named CAR_MIGRATION. When enabled, the address of cache-as-ram variables may be obtained dynamically. Additionally, when cache-as-ram migration occurs the cache-as-ram data region for global variables is copied into cbmem. There are also automatic callbacks for other modules to perform their own migration, if necessary.

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().

2013-05-10Get rid of MAXIMUM_CONSOLE_LOGLEVEL; compile all messages into the coreboot ↵Ronald G. Minnich
binary This option has never had much if any use. It solved a problem over 10 years ago that resulted from an argument over the value or lack thereof of including all the debug strings in a coreboot image. The answer is in: it's a good idea to maintain the capability to print all messages, for many reasons. This option is also misleading people, as in a recent discussion, to believe that log messges are controlled at build time in a way they are not. For the record, from this day forward, we can print messages at all log levels and the default log level is set at boot time, as directed by DEFAULT_CONSOLE_LOGLEVEL. You can set the default to 0 at build time and if you are having trouble override it in CMOS and get more messages. Besides, a quick glance shows it's always set to max (9 in this case) in the very few cases (1) in which it is set. Change-Id: I60c4cdaf4dcd318b841a6d6c70546417c5626f21 Signed-off-by: Ronald G.

Since the TSC udelay() function can be used in SMM that means the TSC can count up to whatever value. The current loop was not handling TSC rollover properly.

However, it is my understanding that this behavior is not guaranteed. Theoretically the TSC could start or be be written to with a large value that would cause the rollover.
