| * [SPARC64]: SUN4U PCI-E controller support.David S. Miller2007-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some minor refactoring in the generic code was necessary for this: 1) This controller requires 8-byte access to the interrupt map and clear register. They are 64-bits on all the other SBUS and PCI controllers anyways, so this was easy to cure. 2) The IMAP register has a different layout and some bits that we need to preserve, so use a read/modify/write when making changes to the IMAP register in generic code. 3) Flushing the entire IOMMU TLB is best done with a single write to a register on this PCI controller, add a iommu->iommu_flushinv for this. Still lacks MSI support, that will come later. Signed-off-by: David S. Miller <davem@davemloft.net>

| * [PATCH] x86: PARAVIRT: add hooks to intercept mm creation and destructionJeremy Fitzhardinge2007-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add hooks to allow a paravirt implementation to track the lifetime of an mm. Paravirtualization requires three hooks, but only two are needed in common code. They are: arch_dup_mmap, which is called when a new mmap is created at fork arch_exit_mmap, which is called when the last process reference to an mm is dropped, which typically happens on exit and exec. The third hook is activate_mm, which is called from the arch-specific activate_mm() macro/function, and so doesn't need stub versions for other architectures. It's called when an mm is first used.

| * [SPARC64]: Add clocksource/clockevents support.David S. Miller2007-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'd like to thank John Stul and others for helping me along the way. A lot of cleanups fell out of this. For example, the get_compare() tick_op was totally unused, so was deleted. And the most often used tick_op members were grouped together for cache-friendlyness. The sparc64 TSC is given to the kernel as a one-shot timer. tick_ops->init_timer() simply turns off the privileged bit in the tick register (when possible), and disables the interrupt by setting bit 63 in the compare register. The ->disable_irq() op also sets this bit. tick_ops->add_compare() is changed to: 1) Add the given delta to "tick" not to "compare" 2) Return a boolean which, if true, means that the tick value read after writing the compare value was found to have incremented past the initial tick value. This mirrors logic used in the HPET driver's ->next_event() method. Each tick_ops implementation also now provides a name string. And we feed this into the clocksource and clockevents layers.

(nanosecond resolution instead of microsecond) Control message is labelled SCM_TIMESTAMPNS instead of SCM_TIMESTAMP A socket cannot mix SO_TIMESTAMP and SO_TIMESTAMPNS : the two modes are mutually exclusive. sock_recv_timestamp() became too big to be fully inlined so I added a __sock_recv_timestamp() helper function.

MSIs are assosciated with MSI Queues. MSI Queues generate interrupts when any MSI assosciated with it is signalled. This suggests a two-tiered IRQ dispatch scheme: MSI Queue interrupt --> queue interrupt handler MSI dispatch --> driver interrupt handler But we just get one-level under Linux currently. What I'd like to do is possibly stick the IRQ actions into a per-MSI-Queue data structure, and dispatch them form there, but the generic IRQ layer doesn't provide a way to do that right now. So, the current kludge is to "ACK" the interrupt by processing the MSI Queue data structures and ACK'ing them, then we run the actual handler like normal. We are wasting a lot of useful information, for example the MSI data and address are provided with ever MSI, as well as a system tick if available. If we could pass this into the IRQ handler it could help with certain things, in particular for PCI-Express error messages. The MSI entries on sparc64 also tell you exactly which bus/device/fn sent the MSI, which would be great for error handling when no registered IRQ handler can service the interrupt. We override the disable/enable IRQ chip methods in sun4v_msi, so we have to call {mask,unmask}_msi_irq() directly from there. This is another ugly wart. Signed-off-by: David S.

* | [PATCH] consolidate line discipline number definitionsTilman Schmidt2007-02-11
|/ | | | | | | | | | | | | | | | | | | The line discipline numbers N_* are currently defined for each architecture individually, but (except for a seeming mistake) identically, in asm/termios.h. There is no obvious reason why these numbers should be architecture specific, nor any apparent relationship with the termios structure. The total number of these, NR_LDISCS, is defined in linux/tty.h anyway. So I propose the following patch which moves the definitions of the individual line disciplines to linux/tty.h too. Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused in the current kernel, but the patch still keeps the complete set in case there are plans to use them yet.
