| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Differentiate AM33_2 and AM33_3 CPU cores in configuration. The MN103E010 processor contains an AM33_2 core. Whilst we're at it, prepare for AM34-based stuff by declaring AM34_2 too.

| * | MN10300: Provide the functions to fully disable maskable interruptsAkira Takeuchi2010-10-271-0/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The local_irq_disable() function and co. merely raise the interrupt mask on the MN10300 arch to exclude normal interrupts. This still lets other, higher priority maskable interrupts through, such as are used to service gdbstub's serial port and the MN10300 on-chip serial port virtual FIFOs. Provide functions to allow the maskable interrupts to be fully disabled, which will exclude those interrupts.

| * | MN10300: Prevent cnt32_to_63() from being preempted in sched_clock()David Howells2010-10-271-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prevent cnt32_to_63() from being preempted in sched_clock() because it may read its internal counter, get preempted, get delayed for more than the half period of the 'TSC' and then write the internal counter, thus corrupting it. Whilst some callers of sched_clock() have interrupts disabled or hold spinlocks, not all do, and so preemption must be held here. Note that sched_clock() is called from lockdep, but that shouldn't be a problem because although preempt_disable() calls into lockdep, lockdep has a recursion counter to deal with this.

A new MSR (MSRC001_103B IBS Branch Target Address) has been added that provides the logical address in canonical form for the branch target. The size of the IBS sample that is transferred to the userland has been increased. For backward compatibility, the userland daemon must explicit enable the feature by writing to the oprofilefs file ibs_op/branch_target After enabling branch target address reporting, the userland daemon must handle the extended size of the IBS sample.

The result of this bug can be a debug printk with a bogus value. Also fix a few more small details that made this function hard to read and which probably contributed to the bug being introduced to begin with: - Use more symmetric error conditions - Remove the !0 obfuscation - Add newlines to the printk output - Remove bogus linebreaks in printk strings and elsewhere Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Cc: Robert Richter <robert.richter@amd.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> LKML-Reference: <20101025115736.41d51abe.sfr@canb.auug.org.au> Signed-off-by: Ingo Molnar <mingo@elte.hu>

This is a problem because esp. BTS tries to allocate a rather large buffer (64K), which can easily fail. This patch changes the logic such that when either buffer allocation fails, we simply don't allow events that would use these facilities, but continue functioning for all other events.

Changes to the enumeration/discovery logic: 1. Use Master Enable bit to signal end of the enumeration - agents may start their discovery process as soon as they see this bit set (Component Tag register was used before for this purpose). 2. Enumerator sets Component Tag (!= 0) immediately during device setup. This allows to identify the device if the redundant route exists in a RIO system.
