2018-01-30target/hppa: Implement tlb_fillRichard Henderson3-10/+197
However since HPPA has a software-managed TLB, and the relevant TLB manipulation instructions are not implemented, this does not actually do anything. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2018-01-30target/hppa: Split address size from register sizeRichard Henderson6-414/+683
For system mode, we will need 64-bit virtual addresses even when we have 32-bit register sizes.

2018-01-29tpm: add CRB deviceMarc-André Lureau10-10/+666
tpm_crb is a device for TPM 2.0 Command Response Buffer (CRB) Interface as defined in TCG PC Client Platform TPM Profile (PTP) Specification Family “2.0” Level 00 Revision 01.03 v22. The PTP allows device implementation to switch between TIS and CRB model at run time, but given that CRB is a simpler device to implement, I chose to implement it as a different device. The device doesn't implement other locality than 0 for now (my laptop TPM doesn't either, so I assume this isn't so bad) Tested with some success with Linux upstream and Windows 10, seabios & modified ovmf. The device is recognized and correctly transmit command/response with passthrough & emu. However, we are missing PPI ACPI part atm.

2018-01-29tpm: replace GThreadPool with AIO threadpoolMarc-André Lureau2-27/+37
The TPM backend uses a GThreadPool to handle IO in a seperate thread. However, GThreadPool isn't integrated with Qemu main loops, making it unnecessarily complicated to deal with. Qemu has a AIO threadpool, that is better integrated with loops and various IO functions, provides completion BH by default etc. Remove the only user of GThreadPool from qemu, use AIO threadpool. Note that the backend: - no longer accepts queing multiple requests (unneeded so far) - increase ref to itself when handling a command, for extra safety - tpm_backend_thread_end() is renamed tpm_backend_finish_sync() and will wait for completion of BH (request_completed), which will help migration handling.

Thus by adding these extra key mappings we are technically changing the host<->guest ABI. This would also happen any time we defined new mappings for QEMU keycodes in future. When a keycode is removed from the list of possible keycodes that host can send to the guest, it means that the guest OS will think it is possible to receive a key that in pratice can never be generated, which is harmless. When a keycode is added to the list of possible keycodes that the host can send to the guest, it means that the guest OS can see an unexpected event. The Linux virtio_input.c driver code simply forwards this event to the input_event() method in the Linux input subsystem. This in turn calls input_handle_event(), which then calls input_get_disposition(). This method checks if the input event is present in the permitted keys bitmap, and if not returns INPUT_IGNORE_EVENT. Thus the unexpected event will get dropped, which is harmless. If the guest OS reboots, or otherwise re-initializes the virt-input device, it will read the new keycode bitmap. No matter how many keys are defined, the config space has a fixed 128 byte bitmap. There is, however, a size field defiend which says how many bytes in the bitmap are used. So the guest OS reads the size of the bitmap, and then it reads the data from bitmap upto the designated size. So if the guest OS re-initializes at precisely the time that QEMU is migrated across versions, in the worst case, it could conceivably read the old size field, but then get the newly updated bitmap. If a key were added this is harmless, since it simply means it may not process the newly added key. If a key were removed, then it could be readnig a byte from the bitmap that was not initialized. Fortunately QEMU always memsets() the entire bitmap to 0, prior to setting keybits. Thus the guest OS will simply read zeros, which is again harmless. Based on this analysis, it is believed that there is no need to preserve the virtio-input-hid keymaps across migration, as the host<->guest ABI change is harmless and self-resolving at time of guest reboot. NB, this behaviour should perhaps be formalized in the virtio-input spec to declare how guest OS drivers should be written to be robust in their handling of the potentially changable key bitmaps.

2018-01-29input: virtio: don't send mouse wheel event twiceMiika S1-2/+4
On Linux, a mouse event is generated for both down and up when mouse wheel is used. This caused virtio_input_send() to be called twice each time the wheel was used. This commit adds a check for the button down state and only calls virtio_input_send() when it is true.

2018-01-29net: Allow netdevs to be used with 'hostfwd_add' and 'hostfwd_remove'Thomas Huth2-12/+25
It does not make much sense to limit these commands to the legacy 'vlan' concept only, they should work with the modern netdevs, too. So now it is possible to use this command with one, two or three parameters. With one parameter, the command installs a hostfwd rule on the default "user" network: hostfwd_add tcp:... With two parameters, the command installs a hostfwd rule on a netdev (that's the new way of using this command): hostfwd_add netdev_id tcp:... With three parameters, the command installs a rule on a 'vlan' (aka hub): hostfwd_add hub_id name tcp:... Same applies to the hostfwd_remove command now.

2018-01-29net: Allow hubports to connect to other netdevsThomas Huth5-12/+32
QEMU can emulate hubs to connect NICs and netdevs. This is currently primarily used for the mis-named 'vlan' feature of the networking subsystem. Now the 'vlan' feature has been marked as deprecated, since its name is rather confusing and the users often rather mis-configure their network when trying to use it. But while the 'vlan' parameter should be removed at one point in time, the basic idea of emulating a hub in QEMU is still good: It's useful for bundling up the output of multiple NICs into one single l2tp netdev for example. Now to be able to use the hubport feature without 'vlan's, there is one missing piece: The possibility to connect a hubport to a netdev, too. This patch adds this possibility by introducing a new "netdev=..." parameter to the hubports. To bundle up the output of multiple NICs into one socket netdev, you can now run QEMU with these parameters for example: qemu-system-ppc64 ... -netdev socket,id=s1,connect=:11122 \ -netdev hubport,hubid=1,id=h1,netdev=s1 \ -netdev hubport,hubid=1,id=h2 -device e1000,netdev=h2 \ -netdev hubport,hubid=1,id=h3 -device virtio-net-pci,netdev=h3 For using the socket netdev, you have got to start another QEMU as the receiving side first, for example with network dumping enabled: qemu-system-x86_64 -M isapc -netdev socket,id=s0,listen=:11122 \ -device ne2k_isa,netdev=s0 \ -object filter-dump,id=f1,netdev=s0,file=/tmp/dump.dat After the ppc64 guest tried to boot from both NICs, you can see in the dump file (using Wireshark, for example), that the output of both NICs (the e1000 and the virtio-net-pci) has been successfully transfered via the socket netdev in this case.

2018-01-29colo: compare the packet based on the tcp sequence numberMao Zhongyi4-119/+250
Packet size some time different or when network is busy. Based on same payload size, but TCP protocol can not guarantee send the same one packet in the same way, like that: We send this payload: ------------------------------ | header |1|2|3|4|5|6|7|8|9|0| ------------------------------ primary: ppkt1: ---------------- | header |1|2|3| ---------------- ppkt2: ------------------------ | header |4|5|6|7|8|9|0| ------------------------ secondary: spkt1: ------------------------------ | header |1|2|3|4|5|6|7|8|9|0| ------------------------------ In the original method, ppkt1 and ppkt2 are different in size and spkt1, so they can't compare and trigger the checkpoint. I have tested FTP get 200M and 1G file many times, I found that the performance was less than 1% of the native. Now I reconstructed the comparison of TCP packets based on the TCP sequence number. first of all, ppkt1 and spkt1 have the same starting sequence number, so they can compare, even though their length is different. And then ppkt1 with a smaller payload length is used as the comparison length, if the payload is same, send out the ppkt1 and record the offset(the length of ppkt1 payload) in spkt1. The next comparison, ppkt2 and spkt1 can be compared from the recorded position of spkt1. like that: ---------------- | header |1|2|3| ppkt1 ---------|-----| | | ---------v-----v-------------- | header |1|2|3|4|5|6|7|8|9|0| spkt1 ---------------|\------------| | \offset | ---------v-------------v | header |4|5|6|7|8|9|0| ppkt2 ------------------------ In this way, the performance can reach native 20% in my multiple tests.
