* | | KVM: Fix dirty page log bitmap size/access calculationUri Lublin2007-03-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Since dirty_bitmap is an unsigned long array, the alignment and size need to take that into account. Signed-off-by: Uri Lublin <uril@qumranet.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
* | | KVM: Add missing calls to mark_page_dirty()Uri Lublin2007-03-041-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | A few places where we modify guest memory fail to call mark_page_dirty(), causing live migration to fail. This adds the missing calls. Signed-off-by: Uri Lublin <uril@qumranet.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
* | | KVM: Per-vcpu inodesAvi Kivity2007-03-044-119/+153
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* | | KVM: Rename some kvm_dev_ioctl_*() functions to kvm_vm_ioctl_*()Avi Kivity2007-03-041-24/+24

* | | KVM: Create an inode per virtual machineAvi Kivity2007-03-041-41/+171
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This avoids having filp->f_op and the corresponding inode->i_fop different, which is a little unorthodox. The ioctl list is split into two: global kvm ioctls and per-vm ioctls. A new ioctl, KVM_CREATE_VM, is used to create VMs and return the VM fd. Signed-off-by: Avi Kivity <avi@qumranet.com>

| * | [libata] change master/slave IDENTIFY orderJeff Garzik2007-03-021-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.21-rc has horrible problems with libata and PATA cable types (and thus speeds). This occurs because Tejun fixed a pile of other bugs and we now do cable detect enforcement for drive side detection properly. Unfortunately we don't do the process around cable detection right. Tejun identified the problem and pointed to the right Annex in the spec, this patch implements the needed changes. The basic requirement is that we have to identify the slave before the master. The patch switches the identify order so that we can do the drive side detection correctly.

| * | libata-core: Fix simplex handlingAlan2007-03-021-3/+2
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The initial simplex handling code is fooled if you suspend and resume. This also causes problems with some single channel controllers which claim to be simplex. The fix is fairly simple, instead of keeping a flag to remember if we gave away the simplex channel we remember the actual owner. As the owner is always part of the host_set we don't even need a refcount. Knowing the owner also means we can reassign simplex DMA channels in future hotplug code etc if we need to Signed-off-by: Alan Cox <alan@redhat.com> (and a signed-off for the patch I sent before while I remember) Signed-off-by: Jeff Garzik <jeff@garzik.org>

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you'll recall, over a year ago, I pointed out that the current Radeon driver erroneously returns -EINVAL for valid blanking codes, here is a link to that thread: http://lkml.org/lkml/2006/1/28/6 No other driver does this, and it confuses the X server into thinking that the device does not support blanking properly. I looked again and there is simply no reason for the Radeon driver to return -EINVAL for FB_BLANK_NORMAL. It claims it wants to do this in order to convince fbcon to blank in software, right here: if (fb_blank(info, blank)) fbcon_generic_blank(vc, info, blank); to software blank the screen. But it only causes that to happen in the FB_BLANK_NORMAL case. That makes no sense because the Radeon code does this: val |= CRTC_DISPLAY_DIS; in the FB_BLANK_NORMAL case so should be blanking the hardware, and there is therefore no reason to SW blank by returning -EINVAL.
