* [POWERPC] Merge iSeries i/o operations with the restStephen Rothwell2006-09-22
| | | | | | | | | This patch changes the io operations so that they are out of line if CONFIG_PPC_ISERIES is set and includes a firmware feature check in that case. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] Define of_read_ulong helperPaul Mackerras2006-09-20
| | | | | | | | | | There are various places where we want to extract an unsigned long value from a device-tree property that can be 1 or 2 cells in length. This replaces some open-coded calculations, and one place where we assumed without checking that properties were the length we wanted, with a little of_read_ulong() helper.

To preserve ordering between writeX and readX, and to preserve ordering between preceding stores and the readX, the readX family of functions have had an sync added before the load. Although writeX followed by spin_unlock is not officially guaranteed to keep the writeX inside the spin-locked region unless an mmiowb() is used, there are currently drivers that depend on the previous behaviour on powerpc, which was that the mmiowb wasn't actually required. Therefore we have a per-cpu flag that is set by writeX, cleared by __raw_spin_lock and mmiowb, and tested by __raw_spin_unlock. If it is set, __raw_spin_unlock does a sync and clears it. This changes both 32-bit and 64-bit readX/writeX. 32-bit already has a sync in __raw_spin_unlock (since lwsync doesn't exist on 32-bit), and thus doesn't need the per-cpu flag. Tested on G5 (PPC970) and POWER5. Signed-off-by: Paul Mackerras <paulus@samba.org>

| | * [POWERPC] Fix irq enable/disable in smp_generic_take_timebasePaul Mackerras2006-08-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eran Ben-Avi <eranpublic@yahoo.com> pointed out that the arch/ppc version of smp_generic_take_timebase disables interrupts on entry but exits without restoring them. However, both it and the arch/powerpc version have another problem, which is that they use local_irq_disable/enable rather than local_irq_save/restore, and they are called with interrupts disabled. This fixes both problems; it changes a return to a break in the arch/ppc version, and changes both versions to use local_irq_save/restore. Signed-off-by: Paul Mackerras <paulus@samba.org>
| | * [POWERPC] Fix problem with time not advancing on 32-bit platformsPaul Mackerras2006-08-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a problem introduced in 5db9fa9593e2ff69f2b95f9d59229dc4faaa564d. The last_jiffy per-cpu variable is only 32 bits on 32-bit machines, but it was being compared with a 64-bit quantity (tb_next_jiffy), which resulted in time not advancing. This fixes it by changing last_jiffy to be 64 bits on all platforms. With this, we no longer need tb_last_stamp as a 32-bit version of tb_last_jiffy, so this gets rid of tb_last_stamp and we just use tb_last_jiffy instead. This also fixes a bug when the boot cpu is not online, because using tb_last_stamp could have caused the wrong timebase origin value to be used when calculating the time of day.

| | * [POWERPC] Make OF irq map code detect more error casesBenjamin Herrenschmidt2006-08-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Device-tree bugs on js20 with some versions of SLOF were causing the interrupt for IDE to not be parsed correctly and fail to boot. This patch adds a bit more sanity checking to the parser to detect some of those errors and fail instead of returning bogus information.

| | * [POWERPC] Fix performance regression in IRQ radix tree lockingBenjamin Herrenschmidt2006-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When reworking the powerpc irq code, I figured out that we were using the radix tree in a racy way. As a temporary fix, I put a spinlock in there. However, this can have a significant impact on performances. This patch reworks that to use a smarter technique based on the fact that what we need is in fact a rwlock with extremely rare writers (thus optimized for the read path).

| * | [PATCH] ppc32: fix last_jiffy time comparisonPaul Mackerras2006-08-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a hang on ppc32. The problem was that I was comparing a 32-bit quantity with a 64-bit quantity, and consequently time wasn't advancing. This makes us use a 64-bit quantity on all platforms, which ends up simplifying the code since we can now get rid of the tb_last_stamp variable (which actually fixes another bug that Ben H and I noticed while going carefully through the code). This works fine on my G4 tibook. Let me know how it goes on your machines.

Some of the masks we use in checking whether the offending instruction is one we care about didn't have the top bit set, which is the MSB of the major opcode.

The first is that there is a race between do_gettimeofday and the timer interrupt: 1. do_gettimeofday does get_tb() 2. decrementer exception on boot cpu which runs timer_recalc_offset, which also samples the timebase and updates the do_gtod structure with a greater timebase value. 3. do_gettimeofday calls __do_gettimeofday, which leads to the negative result from tb_val - temp_varp->tb_orig_stamp. The second is caused by taking the boot cpu offline, which can cause the value of tb_last_jiffy to be increased past the currently available timebase, causing the same underflow as above.

This second processor could have fetched the stream of text from the out-of-line single-stepping area *before* the probe registration completed, possibly due to an earlier (and a different) kprobe hit and hence would see stale data at the slot. Executing such an arbitrary instruction lead to a problem as reported in LTC bugzilla 23555. The correct solution is to call flush_icache_range() as soon as the instruction is copied for out-of-line single-stepping, so the correct instruction is seen on all processors.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the case of a system hang, the user will invoke soft-reset to initiate the kdump boot. If xmon is enabled, the CPU(s) enter into the xmon debugger. Unfortunately, the secondary CPU(s) will return to the hung state when they exit from the debugger (returned from die() -> system_reset_exception()). This causes a problem in kdump since the hung CPU(s) will not respond to the IPI sent from kdump. This patch fixes the issue by calling crash_kexec_secondary() directly from system_reset_exception() without returning to the previous state. These secondary CPUs wait 5ms until the kdump boot is started by the primary CPU. In the case we exited from the debugger to "recover" (command 'x' in xmon) the primary and the secondary CPUs will all return from die() -> system_reset_exception() ->crash_kexec_secondary() wait 5ms, then return to the previous state. A kdump boot is not started in this case. Signed-off-by: Haren Myneni <haren@us.ibm.com> Signed-off-by: David Wilder <dwilder@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
