Commit b2da15ac ("KVM: VMX: Optimize %ds, %es reload") broke i386 in the following scenario: vcpu_load ... vmx_save_host_state vmx_vcpu_run (ds.rpl, es.rpl cleared by hardware) interrupt push ds, es # pushes bad ds, es schedule vmx_vcpu_put vmx_load_host_state reload ds, es (with __USER_DS) pop ds, es # of other thread's stack iret # other thread runs interrupt push ds, es schedule # back in vcpu thread pop ds, es # now with rpl=0 iret ... vcpu_put resume_userspace iret # clears ds, es due to mismatched rpl (instead of resume_userspace, we might return with SYSEXIT and then take an exception; when the exception IRETs we end up with cleared ds, es) Fix by avoiding the optimization on i386 and reloading ds, es on the lightweight exit path.

由 Bruce Rogers 提交于
When a guest migrates to a new host, the system time difference from the previous host is used in the updates to the kvmclock system time visible to the guest, resulting in a continuation of correct kvmclock based guest timekeeping. The wall clock component of the kvmclock provided time is currently not updated with this same time offset. Since the Linux guest caches the wall clock based time, this discrepency is not noticed until the guest is rebooted. After reboot the guest's time calculations are off. This patch adjusts the wall clock by the kvmclock_offset, resulting in correct guest time after a reboot.

After commit 242ec97c PIT interrupts are no longer delivered after PIC reset. It happens because PIT injects interrupt only if previous one was acked, but since on PIC reset it is dropped from irr it will never be delivered and hence acknowledged. Fix that by calling ack notifier on PIC reset. Signed-off-by: NGleb Natapov <gleb@redhat.com> Signed-off-by: NAvi Kivity <avi@redhat.com>

Pull IOMMU updates from Joerg Roedel: "The most important part of these updates is the IOMMU groups code enhancement written by Alex Williamson. It abstracts the problem that a given hardware IOMMU can't isolate any given device from any other device (e.g. 32 bit PCI devices can't usually be isolated). Devices that can't be isolated are grouped together. This code is required for the upcoming VFIO framework. Another IOMMU-API change written by me is the introduction of domain attributes. This makes it easier to handle GART-like IOMMUs with the IOMMU-API because now the start-address and the size of the domain address space can be queried. Besides that there are a few cleanups and fixes for the NVidia Tegra IOMMU drivers and the reworked init-code for the AMD IOMMU. The latter is from my patch-set to support interrupt remapping. The rest of this patch-set requires x86 changes which are not mergabe yet.

Pull networking changes from David S Miller: 1) Remove the ipv4 routing cache. Now lookups go directly into the FIB trie and use prebuilt routes cached there. No more garbage collection, no more rDOS attacks on the routing cache. Instead we now get predictable and consistent performance, no matter what the pattern of traffic we service. This has been almost 2 years in the making. Special thanks to Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who have helped along the way. I'm sure that with a change of this magnitude there will be some kind of fallout, but such things ought the be simple to fix at this point. Luckily I'm not European so I'll be around all of August to fix things :-) The major stages of this work here are each fronted by a forced merge commit whose commit message contains a top-level description of the motivations and implementation issues. 2) Pre-demux of established ipv4 TCP sockets, saves a route demux on input. 3) TCP SYN/ACK performance tweaks from Eric Dumazet. 4) Add namespace support for netfilter L4 conntrack helpers, from Gao Feng. 5) Add config mechanism for Energy Efficient Ethernet to ethtool, from Yuval Mintz. 6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet. 7) Support for connection tracker helpers in userspace, from Pablo Neira Ayuso. 8) Allow userspace driven TX load balancing functions in TEAM driver, from Jiri Pirko. 9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with embedded gotos. 10) TCP Small Queues, essentially minimize the amount of TCP data queued up in the packet scheduler layer. Whereas the existing BQL (Byte Queue Limits) limits the pkt_sched --> netdevice queuing levels, this controls the TCP --> pkt_sched queueing levels. From Eric Dumazet. 11) Reduce the number of get_page/put_page ops done on SKB fragments, from Alexander Duyck. 12) Implement protection against blind resets in TCP (RFC 5961), from Eric Dumazet. 13) Support the client side of TCP Fast Open, basically the ability to send data in the SYN exchange, from Yuchung Cheng. Basically, the sender queues up data with a sendmsg() call using MSG_FASTOPEN, then they do the connect() which emits the queued up fastopen data. 14) Avoid all the problems we get into in TCP when timers or PMTU events hit a locked socket. The TCP Small Queues changes added a tcp_release_cb() that allows us to queue work up to the release_sock() caller, and that's what we use here too. From Eric Dumazet. 15) Zero copy on TX support for TUN driver, from Michael S.

Byte-by-byte transactions are used primarily for accessing I2C devices with an SMBus controller. For these transactions, for each byte that is read or written, the SMBus controller generates a BYTE_DONE IRQ. The isr reads/writes the next byte, and clears the IRQ flag to start the next byte. On the penultimate IRQ, the isr also sets the LAST_BYTE flag. There is no locking around the cmd/len/count/data variables, since the I2C adapter lock ensures there is never multiple simultaneous transactions for the same device, and the driver thread never accesses these variables while interrupts might be occurring. The end result is faster I2C block read and write transactions. Note: This patch has only been tested and verified by doing I2C read and write block transfers on Cougar Point 6 Series PCH, as well as I2C read block transfers on ICH5.

Enable interrupts on more devices. ICH5, ICH7(-M) and ICH10 have been tested to work OK. ICH8 and ICH9 are expected to work just fine as they are very close to ICH7 and ICH10. Ultimately we want to enable this feature on at least every device since the ICH5, but for now we limit the exposure. We'll enable it for other devices if we don't get negative feedback. As a bonus, let the user know when interrupts are used. Signed-off-by: NJean Delvare <khali@linux-fr.org> Cc: Daniel Kurtz <djkurtz@chromium.org>

Add a new 'feature' to i2c-i801 to enable using PCI interrupts. When the feature is enabled, then an isr is installed for the device's PCI IRQ. An I2C/SMBus transaction is always terminated by one of the following interrupt sources: FAILED, BUS_ERR, DEV_ERR, or on success: INTR. When the isr fires for one of these cases, it sets the ->status variable and wakes up the waitq. The waitq then saves off the status code, and clears ->status (in preparation for some future transaction). The SMBus controller generates an INTR irq at the end of each transaction where INTREN was set in the HST_CNT register. No locking is needed around accesses to priv->status since all writes to it are serialized: it is only ever set once in the isr at the end of a transaction, and cleared while no interrupts can occur. In addition, the I2C adapter lock guarantees that entire I2C transactions for a single adapter are always serialized. For this patch, the INTREN bit is set only for SMBus block, byte and word transactions, but not for I2C reads or writes. The use of the DS (BYTE_DONE) interrupt with byte-by-byte I2C transactions is implemented in a subsequent patch. The interrupt feature has only been enabled for COUGARPOINT hardware. In addition, it is disabled if SMBus is using the SMI# interrupt. Signed-off-by: NDaniel Kurtz <djkurtz@chromium.org> Signed-off-by: NJean Delvare <khali@linux-fr.org>

(Based on earlier work by Daniel Kurtz.) Come up with a consistent, driver-wide strategy for event polling. For intermediate steps of byte-by-byte block transactions, check for BYTE_DONE or any error flag being set. At the end of every transaction (regardless of PEC being used), check for both BUSY being cleared and INTR or any error flag being set. This ensures proper action for all transaction types.

If an error is detected in the polling loop, abort the transaction and return an error code. * DEV_ERR is set if the device does not respond with an acknowledge, and the SMBus controller times out (minimum 25ms). * BUS_ERR is set if a bus arbitration collision is detected. In other words, when the SMBus controller tries to generate a START condition, but detects that the SMBDATA is being held low, usually by another SMBus/I2C master. * FAILED is only set if a transaction is stopped by software (using the SMBHSTCNT KILL bit).
