2007-03-05[PATCH] vmi: cpu cycles fixZachary Amsden3-0/+5
In order to share the common code in tsc.c which does CPU Khz calibration, we need to make an accurate value of CPU speed available to the tsc.c code. This value loses a lot of precision in a VM because of the timing differences with real hardware, but we need it to be as precise as possible so the guest can make accurate time calculations with the cycle counters.

2007-03-05[PATCH] vmi: sched clock paravirt op fixZachary Amsden4-3/+11
The custom_sched_clock hook is broken. The result from sched_clock needs to be in nanoseconds, not in CPU cycles. The TSC is insufficient for this purpose, because TSC is poorly defined in a virtual environment, and mostly represents real world time instead of scheduled process time (which can be interrupted without notice when a virtual machine is descheduled). To make the scheduler consistent, we must expose a different nature of time, that is scheduled time. So deprecate this custom_sched_clock hack and turn it into a paravirt-op, as it should have been all along. This allows the tsc.c code which converts cycles to nanoseconds to be shared by all paravirt-ops backends. It is unfortunate to add a new paravirt-op, but this is a very distinct abstraction which is clearly different for all virtual machine implementations, and it gets rid of an ugly indirect function which I ashamedly admit I hacked in to try to get this to work earlier, and then even got in the wrong units.

2007-03-05[PATCH] Page migration: Fix vma flag checkingChristoph Lameter1-0/+8
Currently we do not check for vma flags if sys_move_pages is called to move individual pages. If sys_migrate_pages is called to move pages then we check for vm_flags that indicate a non migratable vma but that still includes VM_LOCKED and we can migrate mlocked pages. Extract the vma_migratable check from mm/mempolicy.c, fix it and put it into migrate.h so that is can be used from both locations.

2007-03-05[PATCH] sched: remove SMT niceCon Kolivas7-11/+0
Remove the SMT-nice feature which idles sibling cpus on SMT cpus to facilitiate nice working properly where cpu power is shared. The idling of cpus in the presence of runnable tasks is considered too fragile, easy to break with outside code, and the complexity of managing this system if an architecture comes along with many logical cores sharing cpu power will be unworkable. Remove the associated per_cpu_gain variable in sched_domains used only by this code. Also: The reason is that with dynticks enabled, this code breaks without yet further tweaks so dynticks brought on the rapid demise of this code. So either we tweak this code or kill it off entirely. It was Ingo's preference to kill it off. Either way this needs to happen for 2.6.21 since dynticks has gone in.

2007-03-05[PATCH] msi: sanely support hardware level msi disablingEric W. Biederman2-3/+5
In some cases when we are not using msi we need a way to ensure that the hardware does not have an msi capability enabled. Currently the code has been calling disable_msi_mode to try and achieve that. However disable_msi_mode has several other side effects and is only available when msi support is compiled in so it isn't really appropriate. Instead this patch implements pci_msi_off which disables all msi and msix capabilities unconditionally with no additional side effects. pci_disable_device was redundantly clearing the bus master enable flag and clearing the msi enable bit. A device that is not allowed to perform bus mastering operations cannot generate intx or msi interrupt messages as those are essentially a special case of dma, and require bus mastering. So the call in pci_disable_device to disable msi capabilities was redundant. quirk_pcie_pxh also called disable_msi_mode and is updated to use pci_msi_off. Signed-off-by: Eric W.

2007-03-04KVM: Per-vcpu inodesAvi Kivity1-21/+17
Allocate a distinct inode for every vcpu in a VM. This has the following benefits: - the filp cachelines are no longer bounced when f_count is incremented on every ioctl() - the API and internal code are distinctly clearer; for example, on the KVM_GET_REGS ioctl, there is no need to copy the vcpu number from userspace and then copy the registers back; the vcpu identity is derived from the fd used to make the call Right now the performance benefits are completely theoretical since (a) we don't support more than one vcpu per VM and (b) virtualization hardware inefficiencies completely everwhelm any cacheline bouncing effects. But both of these will change, and we need to prepare the API today. Signed-off-by: Avi Kivity <avi@qumranet.com>
2007-03-04KVM: Create an inode per virtual machineAvi Kivity1-1/+9

2007-03-02[NET]: Fix bugs in "Whether sock accept queue is full" checkingWei Dong1-1/+1
when I use linux TCP socket, and find there is a bug in function sk_acceptq_is_full(). When a new SYN comes, TCP module first checks its validation. If valid, send SYN,ACK to the client and add the sock to the syn hash table. Next time if received the valid ACK for SYN,ACK from the client. server will accept this connection and increase the sk->sk_ack_backlog -- which is done in function tcp_check_req().We check wether acceptq is full in function tcp_v4_syn_recv_sock(). Consider an example: After listen(sockfd, 1) system call, sk->sk_max_ack_backlog is set to 1. As we know, sk->sk_ack_backlog is initialized to 0. Assuming accept() system call is not invoked now. 1. 1st connection comes. invoke sk_acceptq_is_full(). sk- >sk_ack_backlog=0 sk->sk_max_ack_backlog=1, function return 0 accept this connection. Increase the sk->sk_ack_backlog 2. 2nd connection comes. invoke sk_acceptq_is_full(). sk- >sk_ack_backlog=1 sk->sk_max_ack_backlog=1, function return 0 accept this connection. Increase the sk->sk_ack_backlog 3. 3rd connection comes. invoke sk_acceptq_is_full(). sk- >sk_ack_backlog=2 sk->sk_max_ack_backlog=1, function return 1. Refuse this connection.

This patch provides the following hugetlb-related fixes to the recent stacked shm files changes: - Update is_file_hugepages() so it will reconize hugetlb shm segments. - get_unmapped_area must be called with the nested file struct to handle the sfd->file->f_ops->get_unmapped_area == NULL case. - The fsync f_op must be wrapped since it is specified in the hugetlbfs f_ops. This is based on proposed fixes from Eric Biederman that were debugged and tested by me. Without it, attempting to use hugetlb shared memory segments on powerpc (and likely ia64) will kill your box.
