| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a problem discovered in recent versions of ATI Mach64 driver in X.org on sparc64 architecture. In short, the driver fails to mmap MMIO aperture (PCI resource #2). I've found that kernel's __pci_mmap_make_offset() returns EINVAL. It checks whether user attempts to mmap more than the resource length, which is 0x1000 bytes in our case. But PAGE_SIZE on SPARC64 is 0x2000 and this is what actually is being mmaped. So __pci_mmap_make_offset() failed for this PCI resource. Signed-off-by: Max Dmitrichenko <dmitrmax@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* | | ftrace: disable dynamic ftrace for all archs that use daemonSteven Rostedt2008-10-231-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ftrace daemon is complex and can cause nasty races if something goes wrong. Since it affects all of the kernel, this patch disables dynamic ftrace from any arch that depends on the daemon. Until the archs are ported over to the new MCOUNT_RECORD method, I am disabling dynamic ftrace from them. Note: I am leaving in the arch/<arch>/kernel/ftrace.c code alone since that can be used when the arch is ported to MCOUNT_RECORD. To port the arch to MCOUNT_RECORD, the scripts/recordmcount.pl needs to be updated. I will make that easier to do for 2.6.29. For 28, we will keep the archs disabled.

* | | container freezer: implement freezer cgroup subsystemMatt Helsley2008-10-201-0/+1
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements a new freezer subsystem in the control groups framework. It provides a way to stop and resume execution of all tasks in a cgroup by writing in the cgroup filesystem. The freezer subsystem in the container filesystem defines a file named freezer.state. Writing "FROZEN" to the state file will freeze all tasks in the cgroup. Subsequently writing "RUNNING" will unfreeze the tasks in the cgroup. Reading will return the current state. * Examples of usage : # mkdir /containers/freezer # mount -t cgroup -ofreezer freezer /containers # mkdir /containers/0 # echo $some_pid > /containers/0/tasks to get status of the freezer subsystem : # cat /containers/0/freezer.state RUNNING to freeze all tasks in the container : # echo FROZEN > /containers/0/freezer.state # cat /containers/0/freezer.state FREEZING # cat /containers/0/freezer.state FROZEN to unfreeze all tasks in the container : # echo RUNNING > /containers/0/freezer.state # cat /containers/0/freezer.state RUNNING This is the basic mechanism which should do the right thing for user space task in a simple scenario. It's important to note that freezing can be incomplete. In that case we return EBUSY. This means that some tasks in the cgroup are busy doing something that prevents us from completely freezing the cgroup at this time. After EBUSY, the cgroup will remain partially frozen -- reflected by freezer.state reporting "FREEZING" when read. The state will remain "FREEZING" until one of these things happens: 1) Userspace cancels the freezing operation by writing "RUNNING" to the freezer.state file 2) Userspace retries the freezing operation by writing "FROZEN" to the freezer.state file (writing "FREEZING" is not legal and returns EIO) 3) The tasks that blocked the cgroup from entering the "FROZEN" state disappear from the cgroup's set of tasks.

| * sparc64: Fix disappearing PCI devices on e3500.David S. Miller2008-09-211-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based upon a bug report by Meelis Roos. The OF device layer builds properties by matching bus types and applying 'range' properties as appropriate, up to the root. The match for "PCI" busses is looking at the 'device_type' property, and this does work %99 of the time. But on an E3500 system with a PCI QFE card, the DEC 21153 bridge sitting above the QFE network interface devices has a 'name' of "pci", but it completely lacks a 'device_type' property. So we don't match it as a PCI bus, and subsequently we end up with no resource values at all for the devices sitting under that DEC bridge. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based upon a report by Meelis Roos. Any function call can try to access the current thread register via the _mcount hooks when the kernel is built with -pg (via ftrace or STACK_DEBUG). That can't be setup properly very early on during the bootup of other cpus for sun4u and some early sun4v systems. So add notrace markers to these specific functions, so that _mcount doesn't get invoked too early. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | 1) Testing null with '0' 2) returning void-valued expression Signed-off-by: David S. Miller <davem@davemloft.net>
* | sparc64: Fix sparse warnings in visemul.cDavid S. Miller2008-09-122-7/+6
| | | | | | | | | | | | | | 1) edge8 tables should be static 2) add vis_emul() extern decl. to asm/visasm.h Signed-off-by: David S. Miller <davem@davemloft.net>
* | sparc64: Fix sparse warnings in kernel/time.cDavid S. Miller2008-09-121-11/+11
| | | | | | | | | | | | | | | | | | 1) Using "clock" as a local variable shadows a global variable of the same name declared in linux/clocksource.h 2) rtc_cmos_resource should be static Signed-off-by: David S. Miller <davem@davemloft.net>
* | sysctl: Use header file for sysctl knob declarations on sparc.David S. Miller2008-09-121-0/+1
| | | | | | | | | | | | | | This also takes care of a sparse warning as scons_pwroff's definition point. Signed-off-by: David S. Miller <davem@davemloft.net>
* | sparc64: Fix sparse warnings in global reg snapshotting.David S. Miller2008-09-121-2/+0
| | | | | | | | | | | | | | Lots of shadowed local variables and global_reg_snapshot[] needs an extern declaration in asm/ptrace_64.h. Signed-off-by: David S. Miller <davem@davemloft.net>
* | sparc64: Add __arch64__ to CHECKFLAGSDavid S. Miller2008-09-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | Otherwise sparse doesn't work. The 32 vs. 64 header ifdef used under arch/sparc/include/asm/ is: #if defined(__sparc__) && defined(__arch64__) And that doesn't work for sparse unless we give it __arch64__ Signed-off-by: David S.
