2013-09-02pseries: Fix stalls on hypervisor virtual consoleAnton Blanchard1-0/+2
A number of users are reporting stalls when using the pseries hypervisor virtual console. A simple test case is to paste 15 or 17 characters at a time into the console. Pasting 15 characters at a time works fine but pasting 17 characters hangs for a random amount of time. Other activity (network, qemu monitor etc) unblocks it. If qemu-char tries to send more than 16 characters at once, vty_can_receive returns false. At this point we have to wait for the guest to consume that output. Everything is good so far. The problem occurs when the the guest does consume the output. We need to signal back to the qemu-char layer that we are ready for more input. Without this we block until something else kicks us (eg network activity). Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2013-09-02PPC: E500: Generate device tree on resetAlexander Graf1-9/+43
Today we generate the device tree once on machine initialization and then store the finalized blob in memory to reload it on reset. This is bad for 2 reasons. First we potentially waste a bunch of RAM for no good reason, as we have all information required to regenerate the device tree available anyways. The second reason is even more important. On machine init when we generate the device tree for the first time, we don't have all of the devices fully initialized yet. But the device tree needs to potentially walk devices to put information about them into the device tree. Move the generation into a reset function. That way we just generate it new every time we reset, solving both of the above issues. Signed-off-by: Alexander Graf <agraf@suse.de>

2013-08-30Merge remote-tracking branch 'borntraeger/tags/kdump' into stagingAnthony Liguori9-19/+204
This is a set of patches dealing with kdump support for s390x/kvm. kdump on s390x uses subcode 1 of diagnose 0x308 to put the hardware in a defined state. This is different from a full reset, since it does not touch all CPU registers. These patches define the cpu resets, the subsystem reset a load function and also wires up the "nmi" command to issue a RESTART interrupt as defined in the z/Architecture principles of operation. This allows recent guest kernels with properly setup userspace to trigger kdump: - via guest crash - via nmi from the host # gpg: Signature made Fri 30 Aug 2013 07:19:18 AM CDT using RSA key ID B5A61C7C # gpg: Can't check signature: public key not found # By Christian Borntraeger (5) and Eugene (jno) Dvurechenski (2) # Via Christian Borntraeger * borntraeger/tags/kdump: s390: wire up nmi command to raise a RESTART interrupt on S390 s390: Implement load normal reset s390/cpu: split CPU reset into architectured functions s390: provide a cpu load normal function s390: provide I/O subsystem reset s390/kvm: basic implementation of diagnose 308 subcode 6 s390x/kvm: Fix switch/case indentation for handle_diag Message-id: 1377810649-47484-1-git-send-email-borntraeger@de.ibm.com
2013-08-30s390: wire up nmi command to raise a RESTART interrupt on S390Eugene (jno) Dvurechenski5-6/+33
There is the 'nmi' command that is used to trigger a guest dump via kdump feature on x86. s390 uses RESTART interrupt to trigger kdump. So, this patch provides a mean to use 'nmi' command on s390 to raise RESTART interrupt. The CPU to receive the RESTART interrupt is the "default" one. There is an infrastructure to select the "default" CPU using 'cpu' command. The 'info cpus' command can be used to see which one is the "default". In order to wire up the RESTART to 'nmi' command we had to: 1. implement the kvm_s390_cpu_restart function by exporting the existing code 2. implement s390_cpu_restart function as kvm-aware wrapper 3. modify the qmp_inject_nmi function to enable (for s390) the scan for "default" CPU and call s390_cpu_restart for it; 3. fix some messages.

2013-08-30s390: Implement load normal resetChristian Borntraeger1-0/+30
kdump on s390 uses a load normal reset to bring the system in a defined state by doing a subsystem reset. The issuing CPUs will have an initial CPU reset, all other CPUs will have a CPU reset as defined in POP (no register content will change). Implement this as architectured.

2013-08-30s390/cpu: split CPU reset into architectured functionsChristian Borntraeger2-3/+39
s390 provides several CPU resets: - CPU reset, clears interrupts, stop processing, clears TLB, but does not touch registers - initial CPU reset, like CPU reset, but also clears PSW, prefix, FPC, timer and control registers. It does not touch gprs, fprs and acrs (!) - Power on reset: the full monty wire up CPUClass reset to the full monty, but provide the lesser resets as part of S390CPUClass.

This patch allows auto completion work normal for sub command case, "info block [DEVICE]" can auto complete now, by re-enter the completion function. In original code "info" is treated as a special case, now it is treated as a sub command group, global variable info_cmds is not used any more. "help" command is still treated as a special case, since it is not a sub command group but want to auto complete command in root command table.

2013-08-30monitor: refine monitor_find_completion()Wenchao Xia1-26/+39
In order to support sub command in auto completion, a reentrant function is needed, so monitor_find_completion() is split into two parts. The first part does parsing of user input which need to be done only once, the second part does the auto completion job according to the parsing result, which contains the necessary code to support sub command and works as the reentrant function. The global "info_cmds" is still used in second part, which will be replaced by sub command code later.

2013-08-30monitor: support sub command in helpWenchao Xia1-10/+52
The old code in help_cmd() uses global 'info_cmds' and treats it as a special case. Actually 'info_cmds' is a sub command group of 'mon_cmds', in order to avoid direct use of it, help_cmd() needs to change its work mechanism to support sub command and not treat it as a special case any more. To support sub command, help_cmd() will first parse the input and then call help_cmd_dump(), which works as a reentrant function. When it meets a sub command, it simply enters the function again. Since help dumping needs to know whole input to printf full help message include prefix, for example, "help info block" need to printf prefix "info", so help_cmd_dump() takes all args from input and extra parameter arg_index to identify the progress. Another function help_cmd_dump_one() is introduced to printf the prefix and command's help message. Now help supports sub command, so later if another sub command group is added in any depth, help will automatically work for it. Still "help info block" will show error since command parser reject additional parameter, which can be improved later. "log" is still treated as a special case.

2013-08-30monitor: refine parse_cmdline()Wenchao Xia1-11/+40
Since this function will be used by help_cmd() later, so improve it to make it more generic and easier to use. free_cmdline_args() is added too as paired function to free the result. One change of this function is that, when the valid args in input exceed the limit of MAX_ARGS, it fails now, instead of return with MAX_ARGS of parsed args in old code. This should not impact much since it is rare that user input many args in monitor's "help" and auto complete scenario.
