The following patch defines sigcontext ABI of ColdFire. Due to ISA restrictions ColdFire needs different rt_sigreturn trampoline. And due to ColdFire FP registers being 8-bytes instead of 12-bytes on m68k, sigcontext and fpregset structures should be updated. Regarding the sc_fpstate[16+6*8] field, it would've been enough 16 bytes to store ColdFire's FP state. To accomodate GLIBC's libSegFault it would'be been enough 6*8 bytes (room for the 6 non-call-clobbered FP registers). I set it to 16+6*8 to provide some extra space for any future changes in the ColdFire FPU. Signed-off-by:

Maxim Kuvyrkov authored
This patch adds several syscalls, that provide necessary functionality to support NPTL on m68k/ColdFire. The syscalls are get_thread_area, set_thread_area, atomic_cmpxchg_32 and atomic_barrier. The cmpxchg syscall is required for ColdFire as it doesn't support 'cas' instruction. Also a ptrace call PTRACE_GET_THREAD_AREA is added to allow debugger to inspect the TLS storage. Signed-off-by:

This patch switches m68k to generic siginfo layout. The custom layout of m68k's `struct siginfo' had several issues due to not considering aliasing of members in the union, e.g., _uid32 was at different offsets in ._kill, ._rt and ._sigchld. Signed-off-by:

Lots of changes. Remove volatile keywords. Take the advice in the comments and change video_slot to slot_addr. Factor out fifteen or so "channel >> 8" shifts into three shifts higher up the call graph. Make csc_setpalette() atomic, pass the correct color values. Check for ioremap() failure. Add missing break statement, thus fixing 24 bit console visual (blue background bug). Remove some uninformative printk() noise. Add a description for powerbook 140/170 graphics. Signed-off-by:

Valkyriefb and macfb will adopt the same card if they get the chance, so remove valkyrie support from macfb. Also fix the "valkyriefb: can't do 832x624x8" problem reported by Raylynn Knight some time ago, by adding vmode 13 support for CONFIG_MAC. Also add vmode 11 since that works too. Make use of the monitor sense lines on 68k Macs too. Also some cleanups. Signed-off-by:

Finn Thain authored
The valkyriefb driver assumes that this logic holds: mac_vmode_to_var(X, cmode, &var); mac_var_to_vmode(&var, &vmode, &cmode); assert(vmode == X); But it doesn't hold because mac_var_to_vmode() can return a mode with a slower pixel clock, even when a match is available. So we end up with this failure: using video mode 11 and color mode 0. valkyriefb: vmode 12 not valid. valkyriefb: can't set default video mode valkyriefb: vmode 12 not valid. Rather than have mac_var_to_mode() return the first reasonable mode it finds, have it return the mode that is closest to the requested one (or the mode with the closest longer pixel clock period if there is no exact match).

The GT-64111 PCI host bridge has no address translation mechanism, so it can't generate legacy port accesses. This quirk fixes legacy device port resources to contain the bus addresses actually generated by the GT-64111. I think this is the approach Ben Herrenschmidt suggested long ago: http://marc.info/?l=linux-kernel&m=119733290624544&w=2 This allows us to remove the IORESOURCE_PCI_FIXED hack from pcibios_fixup_device_resources(), which converts bus addresses to CPU addresses. IORESOURCE_PCI_FIXED denotes resources that can't be moved; it has nothing to do with converting bus to CPU addresses.

On Alchemy the PCMCIA area lies at the end of the chips 36bit system bus area. Currently, addresses at the far end of the 32bit area are assumed to belong to the PCMCIA area and fixed up to the real 36bit address before being passed to ioremap(). A previous commit enabled 64 bit physical size for the resource datatype on Alchemy and this allows to use the correct 36bit addresses when registering the PCMCIA sockets. This patch removes the 32-to-36bit address fixup and registers the Alchemy demo board pcmcia socket with the correct 36bit physical addresses. Tested on DB1200, with a CF card (ide-cs driver) and a 3c589 PCMCIA ethernet card. Signed-off-by:

Because the VIA SuperIO chip only decodes 24 bits of address space but port address space currently being configured as 32MB there is the theoretical possibility of aliases within the I/O port address range. The complicated solution is to reserve all address range that potencially could cause such aliases. But with the PCI spec limiting port allocations for devices to a maximum of 256 bytes 16MB of port address space already is way more than one would ever expect to be used so we just reduce the port space to 16MB.

This is just a test program for raw_spinlocks. The main reason I wrote it is to validate my spinlock changes that I sent in a previous patch. To use it enable CONFIG_DEBUG_FS and CONFIG_SPINLOCK_TEST then at run time do: # mount -t debugfs none /sys/kernel/debug/ # cat /sys/kernel/debug/mips/spin_single # cat /sys/kernel/debug/mips/spin_multi On my 600MHz octeon cn5860 (16 CPUs) I get spin_single spin_multi base 106885 247941 spinlock_patch 75194 219465 This shows that for uncontended locks the spinlock patch gives 41% improvement and for contended locks 12% improvement (1/time).

The current locking mechanism uses a ll/sc sequence to release a spinlock. This is slower than a wmb() followed by a store to unlock. The branching forward to .subsection 2 on sc failure slows down the contended case. So we get rid of that part too. Since we are now working on naturally aligned u16 values, we can get rid of a masking operation as the LHU already does the right thing. The ANDI are reversed for better scheduling on multi-issue CPUs On a 12 CPU 750MHz Octeon cn5750 this patch improves ipv4 UDP packet forwarding rates from 3.58*10^6 PPS to 3.99*10^6 PPS, or about 11%.
