2016-07-12linux-user: Clean up target_cpu.h header guardsMarkus Armbruster
These headers all use TARGET_CPU_H as header guard symbol. Reuse of the same guard symbol in multiple headers is okay as long as they cannot be included together. Since we can avoid guard symbol reuse easily, do so: use guard symbol $target_TARGET_CPU_H for linux-user/$target/target_cpu.h.

2016-07-12linux-user: Clean up target_syscall.h header guardsMarkus Armbruster
Some of them use guard symbol TARGET_SYSCALL_H, but we also have CRIS_SYSCALL_H, MICROBLAZE_SYSCALLS_H, TILEGX_SYSCALLS_H and __UC32_SYSCALL_H__. They all upset scripts/clean-header-guards.pl. Reuse of the same guard symbol TARGET_SYSCALL_H in multiple headers is okay as long as they cannot be included together. The script can't tell, so it warns. The script dislikes the other guard symbols, too. They don't match their file name (they should, to make guard collisions less likely), and __UC32_SYSCALL_H__ is a reserved identifier. Clean them all up: use guard symbol $target_TARGET_SYSCALL_H for linux-user/$target/target_sycall.h.

2016-07-12scripts: New clean-header-guards.plMarkus Armbruster
The conventional way to ensure a header can be included multiple times is to bracket it like this: #ifndef HEADER_NAME_H #define HEADER_NAME_H ... #endif where HEADER_NAME_H is a symbol unique to this header. The endif may be optionally decorated like this: #endif /* HEADER_NAME_H */ Unconventional ways present in our code: * Identifiers reserved for any use: #define _FILEOP_H * Lowercase (bad idea for object-like macros): #define __linux_video_vga_h__ * Roundabout ways to say the same thing (and hide from grep): #if !defined(__PPC_MAC_H__) #endif /* !defined(__PPC_MAC_H__) */ * Redundant values: #define HW_ALPHA_H 1 * Funny redundant values: # define PXA_H "pxa.h" * Decorations with bangs: #endif /* !QEMU_ARM_GIC_INTERNAL_H */ The negation actually makes sense, but almost all our header guard #endif decorations don't negate. * Useless decorations: #endif /* audio.h */ Header guards are not the place to show off creativity. This script normalizes them to the conventional way, and cleans up whitespace while there. It warns when it renames guard symbols, and explains how to find occurences of these symbols that may have to be updated manually. Another issue is use of the same guard symbol in multiple headers. That's okay only for headers that cannot be used together, such as the *-user/*/target_syscall.h. This script can't tell, so it warns when it sees a reuse. The script also warns when preprocessing a header with its guard symbol defined produces anything but whitespace. The next commits will put the script to use.

2016-07-12hw/mips: implement Global Interrupt ControllerYongbok Kim
The Global Interrupt Controller (GIC) is responsible for mapping each internal and external interrupt to the correct location for servicing. The internal representation of registers is different from the specification in order to consolidate information for each GIC Interrupt Sources and Virtual Processors with same functionalities. For example SH_MAP00_VP00 registers are defined like each bit represents a VP but in this implementation the equivalent map_vp contains VP number in integer form for ease accesses. When it is being accessed via read write functions an internal data is converted back into the original format as the specification.

2016-07-12hw/mips: implement GIC Interval TimerYongbok Kim
The interval timer is similar to the CP0 Count/Compare timer within each processor. The difference is the GIC_SH_COUNTER register is global to the system so that all processors have the same time reference. To ease implementation, all VPs are having its own QEMU timer but sharing global settings and registers such as GIC_SH_CONFIG.COUTNSTOP and GIC_SH_COUNTER. MIPS GIC Interval Timer does support upto 64 bits of Count register but in this implementation it is limited to 32 bits only.

2016-07-12msmouse: fix buffer handlingGerd Hoffmann
The msmouse chardev backend writes data without checking whenever there is enough space. That happens to work with linux guests, probably by pure luck because the linux driver enables the fifo and the serial port emulation accepts more data than announced via qemu_chr_be_can_write() in that case. Handle this properly by adding a buffer to MouseState. Hook up a CharDriverState->accept_input() handler which feeds the buffer to the serial port. msmouse_event() only fills the buffer now, and calls the accept_input handler too to kick off the transmission.

2016-07-12ui: avoid crash if vnc client disconnects with writes pendingDaniel P. Berrange
The vnc_client_read() function is called from the vnc_client_io() event handler callback when there is incoming data to process. If it detects that the client has disconnected, then it will trigger cleanup and free'ing of the VncState client struct at a safe time. Unfortunately, the vnc_client_io() event handler will also call vnc_client_write() to handle any outgoing data writes. So if vnc_client_io() was invoked with both G_IO_IN and G_IO_OUT events set, and the client disconnects, we may try to write to a client which has just been freed. https://bugs.launchpad.net/qemu/+bug/1594861 Signed-off-by: Daniel P.

2016-07-11s390x/pci: make hot-unplug handler smootherYi Min Zhao
The current implementation of hot-unplug handler is abrupt. Any pci operation will be just rejected if pci device is unconfigured. Thus a pci device can not be reset or destroyed in a right, smooth and safe way. Improve this as follows: - Notify the guest via a HP_EVENT_DECONFIGURE_REQUEST(0x303) event in the unplug handler, giving it a chance to deconfigure the device via sclp and allowing us to continue hot-unplug afterwards. - Set up a timer that will generate the HP_EVENT_CONFIGURE_TO_STBRES (0x304) event as before if the guest did not react after an adequate time.

2016-07-11s390x/pci: replace fid with idx in msg data of msixYi Min Zhao
Present code uses fid as the part of message data of msix for looking up the specific zpci device. However it limits the usable range of fid, and the code looking up the zpci device may fail due to truncation of the fid. In addition, fh is composed of enabled bit, FH_VIRT and the array index. So we can use the array index as the identifier to store in msg data.

2016-07-11s390x/pci: fix stpcifc_service_callYi Min Zhao
Firstly the function misses dmaas checking. This patch adds it. Secondly the function uses s390_pci_find_dev_by_fh() to look up the zpci device. This may fail if the guest provides a valid and disabled fh but fh of the associated zpci device is enabled. Thus we use s390_pci_find_dev_by_idx() instead.

Because of the refactor of s390_pci_find_dev_by_idx(), list_pci() should be updated. We introduce a new function to get the next available zpci device. It simplifies the code of looking up zpci devices.

2016-07-11s390x/pci: refactor s390_pci_find_dev_by_idxYi Min Zhao
s390_find_dev_by_idx() only indexes usable zpci devices. It implies that the index value of each zpci device is dynamic and may change if a new zpci device is plugged. So we have to use a constant index to look up the device.

2016-07-11s390x/pci: introduce S390PCIBusDevice qdevYi Min Zhao
To support definitions of s390 pci attributes in Qemu cmdline, we have to make current S390PCIBusDevice struct inherit DeviceState and add three properties for it. Currently we only support definitions of uid and fid. 'uid' is optionally defined by users, identifies a zpci device and must be defined with a 16-bit and non-zero unique value. 'fid' ranges from 0x0 to 0xFFFFFFFF. For fid property, we introduce a new PropertyInfo by the name of s390_pci_fid_propinfo with our special setter and getter. As 'fid' is optional, introduce 'fid_defined' to track whether the user specified a fid. 'target' field is to direct qemu to find the corresponding generic PCI device. It is equal to the 'id' value of one of generic pci devices. If the user doesn't specify 'id' parameter for a generic pci device, its 'id' value will be generated automatically and use this value as 'target' to create an associated zpci device. If the user did not specify 'uid' or 'fid', values are generated automatically. 'target' is required. In addition, if a pci device has no associated zpci device, the code will generate a zpci device automatically for it.

2016-07-11s390x/pci: introduce S390PCIIOMMUYi Min Zhao
Currently each zpci device holds its own DMA address space and memory region. At the same time, all instances of zpci device are stored in S390pciState. So duirng the initialization of S390pciState, all zpci devices are created and then all DMA address spaces are created. Thus, when initializing pci devices, their corresponding DMA address spaces could be found. But zpci qdev will be introduced later. Zpci device may be initialized and plugged afterwards generic pci device. So we should initialize all DMA address spaces and memory regions before initializing zpci devices. We introduce a new struct named S390PCIIOMMU. And a new field of S390pciState, which is an array to store all instances of S390PCIIOMMU, is added so that qemu pci code could find the corresponding DMA address space when initializing a generic pci device. And this should be done before the connection of a zpci device and a generic pci device is built.
