We use clock cycle counter, adjusted to HZ. This can be extended to sun4v based processors as well, as they also have a proper overflow interrupt facility for the performance counters. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

In these instructions we load the new thread register, switch the register window, and setup the new frame pointer. All of these must appear atomic, and things will explode if we take a PIL=15 NMI interrupt in the middle of this sequence. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

So that we can profile code even in a local_irq_disable() section, only write 14 (instead of 15) into the %pil register to disable IRQs. This allows PIL level 15 to serve as a pseudo NMI. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Stephen Rothwell pointed out that pcmcia can't be enabled on sparc64. There is an empty non-prompt PCMCIA explicit entry in arch/sparc/Kconfig but that doesn't do anything. 32-bit sparc needs a small hack to make this work, since it doesn't use the generic IRQ layer yes. We have to provide a dummy definition of probe_irq_mask(), since this is used by the yenta socket driver. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Add a sysctl to tweak the RSS limit used to decide when to grow the TSB for an address space. In order to avoid expensive divides and multiplies only simply positive and negative powers of two are supported. The function computed takes the number of TSB translations that will fit at one time in the TSB of a given size, and either adds or subtracts a percentage of entries. This final value is the RSS limit. See tsb_size_to_rss_limit(). Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Merge all of sparc64 Kconfig to sparc Kconfig. The merge was checked by: - visual inspection in menuconfig - result of allnoconfig, allmodconfig, allyesconfig was checked before and after - result of a number of randconfig was checked before and after scripts/diffconfig was used to check if the config differed before and after The validity of the test was checked by on purpose introducing a few bugs - and they were all caught by first run.

The fact of the matter is, all UltraSPARC-III and later chips only implement TSO. They don't implement PSO and RMO memory models at all. Only the Ultra-I and Ultra-II family chips implement RMO and they are only helped marginally by using this setting when executing kernel code. The big plus to doing this is that we can eliminate all of the non-Sync memory barriers in the kernel except for the ones used in the optimized memcpy/memset code (these use block load and store operations which have their own memory ordering rules).

This patch fixes some bugs in VIS emulation that cause the GCC test failure FAIL: gcc.target/sparc/pdist-3.c execution test for both 32-bit and 64-bit testing on hardware lacking these instructions. The emulation code for the pdist instruction uses RS1(insn) for both source registers rs1 and rs2, which is obviously wrong and leads to the instruction doing nothing (the observed problem), and further inspection of the code shows that RS1 uses a shift of 24 and RD a shift of 25, which clearly cannot both be right; examining SPARC documentation indicates the correct shift for RS1 is 14. This patch fixes the bug if single-stepping over the affected instruction in the debugger, but not if the testcase is run standalone. For that, Wind River has another patch I hope they will send as a followup to this patch submission. Signed-off-by: NJoseph Myers <joseph@codesourcery.com> Signed-off-by: NDavid S.

The code used '&= 0x00002000' when it tried to set the TCO_EN bit, which obviously didn't set that bit at all, but instead just reset all the other bits in the SMI_EN register. This bug seemingly caused various random behavior, with Frans Pop reporting that X.org just silently hung at startup and Rafael Wysocki reports the fan spinning with full speed. See http://lkml.org/lkml/2008/12/3/178 http://bugzilla.kernel.org/show_bug.cgi?id=12162 The problem seems to have been triggered by "[WATCHDOG] iTCO_wdt : problem with rebooting on new ICH9 based motherboards" (commit 7cd5b08b), but the bogus code existed before that too (in the "supermicro_old_pre_stop()" function), it just apparently never showed up due to different logic. In that commit the broken code got moved around and now gets executed much more. Reported-by: NRafael J.
