A lot of the options in arch/powerpc/Kconfig deal with the CPU menu, and my next patches add more to them. Moving them to a new arch/powerpc/platforms/Kconfig.cputype file makes it easier to follow. There are no functional changes in here. Signed-off-by: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NPaul Mackerras <paulus@samba.org>

We have had complaints where a threaded application is left in a bad state after one of it's threads is killed when we hit a VM: out_of_memory condition. Killing just one of the process threads can leave the application in a bad state, whereas killing the entire process group would allow for the application to restart, or be otherwise handled, and makes it very obvious that something has gone wrong. This change allows the entire process group to be taken down, rather than just the one thread. lightly tested on powerpc Signed-off-by: NWill <will_schmidt@vnet.ibm.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

A Power6 can give up CPU cycles on a dedicated CPU (as opposed to a shared CPU) to other shared processors if the administrator asks for it (via the HMC). This enables that to work properly on P6. This just involves setting a bit in the CAS structure as well as the VPA. To donate cycles, a CPU has to have all SMT threads idle and have the donate bit set in the VPA. Then call H_CEDE. The reason why shared processors just aren't used is because dedicated CPUs are guaranteed an actual processor, yet the system is still able to increase the capacity of the shared CPU pool. Also rename the VPA's cpuctls_task_attrs field to a more accurate name. Signed-off-by: NJake Moilanen <moilanen@austin.ibm.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

The code for creating signal frames was still duplicated and split in strange ways between 32 and 64 bits, including the SA_ONSTACK handling being in do_signal on 32 bits but inside handle_rt_signal on 64 bits etc... This moves the 64 bits get_sigframe() to the generic signal.c, cleans it a bit, moves the access_ok() call done by all callers to it as well, and adapts/cleanups the 3 different signal handling cases to use that common function.

do_signal has exactly the same behaviour on 32bit and 64bit and 32bit compat on 64bit for handling 32bit signals. Consolidate all these into one common function in signal.c. The only odd left over is the try_to_free in the 32bit version that no other architecture has in mainline (only in i386 for some odd SuSE release). We should probably get rid of it in a separate patch.

sys_sigaltstack is the same on 32bit and 64 and we can consolidate it to signal.c. The only difference is that the 32bit code uses ints for the unused register paramaters and 64bit unsigned long. I've changed it to unsigned long because it's the same width on 32bit.

This patch moves the code in signal_32.c and signal_64.c for handling syscall restart into a common signal.c file and converge around a single implementation that is based on the 32 bits one, using trap, ccr and r3 rather than the special "result" field for deciding what to do. The "result" field is now pretty much deprecated. We still set it for the sake of whatever might rely on it in userland but we no longer use it's content. This, along with a previous patch that enables ptracers to write to "trap" and "orig_r3" should allow gdb to properly handle syscall restarting.

This patch removes the #ifdef CONFIG_PPC64 around setting the DABR. The actual setting of the SPR inside of the set_dabr() function is dependent on CONFIG_PPC64 || CONFIG_6xx but you can always provide a ppc_md hook to override that. We should improve support for different HW breakpoints facilities but this is a first step.

One of the gratuitous difference between 32 and 64-bit ptrace is whether you can whack the MSR:FE0 and FE1 bits from ptrace. This patch forbids it unconditionally. In addition, the 64-bit kernels used to return the exception mode in the MSR on reads, but 32-bit kernels didn't. This patch makes it return those bits on both. Finally, since ptrace-ppc32.h and ptrace-ppc64.h are mostly empty now, and since the previous patch made ptrace32.c no longer need the MSR_DEBUGCHANGE definition, we just remove those 2 files and move back the remaining bits to ptrace.c (they were short lived heh ?).

This patch allows a ptracer to write to the "trap" and "orig_r3" words of the pt_regs. This, along with a subsequent patch to the signal restart code, should enable gdb to properly handle syscall restarting after executing a separate function (at least when there's no restart block). This patch also removes ptrace32.c code toying directly with the registers and makes it use the ptrace_get/put_reg() accessors for everything so that the logic for checking what is permitted is in only one place.

The powerpc ptrace interface is dodgy at best. We have defined our "own" versions of GETREGS/SETREGS/GETFPREGS/SETFPREGS that strangely take arguments in reverse order from other archs (in addition to having different request numbers) and have subtle issue, like not accessing all of the registers in their respective categories. This patch moves the implementation of those to a separate function in order to facilitate their deprecation in the future, and provides new ptrace requests that mirror the x86 and sparc ones and use the same numbers: PTRACE_GETREGS : returns an entire pt_regs (the whole thing, not only the 32 GPRs, though that doesn't include the FPRs etc... There's a compat version for 32 bits that returns a 32 bits compatible pt_regs (44 uints) PTRACE_SETREGS : sets an entire pt_regs (the whole thing, not only the 32 GPRs, though that doesn't include the FPRs etc... Some registers cannot be written to and will just be dropped, this is the same as with POKEUSR, that is anything above MQ on 32 bits and CCR on 64 bits. There is a compat version as well. PTRACE_GETFPREGS : returns all the FP registers -including- the FPSCR that is 33 doubles (regardless of 32/64 bits) PTRACE_SETFPREGS : sets all the FP registers -including- the FPSCR that is 33 doubles (regardless of 32/64 bits) And two that only exist on 64 bits kernels: PTRACE_GETREGS64 : Same as PTRACE_GETREGS, except there is no compat function, a 32 bits process will obtain the full 64 bits registers PTRACE_SETREGS64 : Same as PTRACE_SETREGS, except there is no compat function, a 32 bits process will set the full 64 bits registers The two later ones makes things easier to have a 32 bits debugger on a 64 bits program (or on a 32 bits program that uses the full 64 bits of the GPRs, which is possible though has issues that will be fixed in a later patch). Finally, while at it, the patch removes a whole bunch of code duplication between ptrace32.c and ptrace.c, in large part by having the former call into the later for all requests that don't need any special "compat" treatment.

The powerpc ptrace code has some weirdness, like a ptrace-common.h file that is actually ppc64 only and some of the 32 bits code ifdef'ed inside ptrace.c. There are also separate implementations for things like get/set_vrregs for 32 and 64 bits which is totally unnecessary. This patch cleans that up a bit by having a ptrace-common.h which contains really common code (and makes a lot more code common), and ptrace-ppc32.h and ptrace-ppc64.h files that contain the few remaining different bits.

This rewrites pretty much from scratch the handling of MMIO and PIO space allocations on powerpc64. The main goals are: - Get rid of imalloc and use more common code where possible - Simplify the current mess so that PIO space is allocated and mapped in a single place for PCI bridges - Handle allocation constraints of PIO for all bridges including hot plugged ones within the 2GB space reserved for IO ports, so that devices on hotplugged busses will now work with drivers that assume IO ports fit in an int. - Cleanup and separate tracking of the ISA space in the reserved low 64K of IO space. No ISA -> Nothing mapped there. I booted a cell blade with IDE on PIO and MMIO and a dual G5 so far, that's it :-) With this patch, all allocations are done using the code in mm/vmalloc.c, though we use the low level __get_vm_area with explicit start/stop constraints in order to manage separate areas for vmalloc/vmap, ioremap, and PCI IOs. This greatly simplifies a lot of things, as you can see in the diffstat of that patch :-) A new pair of functions pcibios_map/unmap_io_space() now replace all of the previous code that used to manipulate PCI IOs space. The allocation is done at mapping time, which is now called from scan_phb's, just before the devices are probed (instead of after, which is by itself a bug fix). The only other caller is the PCI hotplug code for hot adding PCI-PCI bridges (slots). imalloc is gone, as is the "sub-allocation" thing, but I do beleive that hotplug should still work in the sense that the space allocation is always done by the PHB, but if you unmap a child bus of this PHB (which seems to be possible), then the code should properly tear down all the HPTE mappings for that area of the PHB allocated IO space. I now always reserve the first 64K of IO space for the bridge with the ISA bus on it. I have moved the code for tracking ISA in a separate file which should also make it smarter if we ever are capable of hot unplugging or re-plugging an ISA bridge. This should have a side effect on platforms like powermac where VGA IOs will no longer work. This is done on purpose though as they would have worked semi-randomly before. The idea at this point is to isolate drivers that might need to access those and fix them by providing a proper function to obtain an offset to the legacy IOs of a given bus.

This makes unmap_vm_area static and a wrapper around a new exported unmap_kernel_range that takes an explicit range instead of a vm_area struct. This makes it more versatile for code that wants to play with kernel page tables outside of the standard vmalloc area. (One example is some rework of the PowerPC PCI IO space mapping code that depends on that patch and removes some code duplication and horrible abuse of forged struct vm_struct).

Previously, registering this early console would just result in dropping early buffered printk output until a udbg_putc was registered. However, commit 69331af7 clears the CON_PRINTBUFFER flag on the main console when a CON_BOOT (early) console has been registered, resulting in the buffered messages never being displayed to the user.
