2012-03-05cc32rs512: add simulation of the built-in flash controllerHEADmasterHarald Welte1-5/+215
2012-03-05Initial support for the ChipCity CC32RS512 smart cardHarald Welte2-0/+528
The CC32RS512 is a Smart Card SoC, based on an SC100 ARM core, 18kByte RAM and 512kByte FLASH. It contains a number of integrated peripherals such as the ISO7816 Slave Controller, AES,DES, etc. This emulator is just emulating very basic behavior at this point.

2012-03-02hw/arm11mpcore: Fix broken realview_mpcore/arm11mpcore_priv propertiesPeter Maydell1-10/+10
Fix confusion in the Property arrays for the "arm11mpcore_priv" (per-CPU devices for the ARM11MPcore CPU) and "realview_mpcore" (realview-eb board specific device encapsulating CPU and some extra interrupt controllers) -- the num-irq property was defined on the wrong device and the mpcore_rirq_properties were defined as offsets in the wrong structure. The effect was that the realview-eb-mpcore machine would abort on startup trying to allocate an insane amount of memory. (This bug was introduced in the QOM conversion in commit 999e12bb.)

2012-02-29fdc: take side count into accountHervé Poussineau1-6/+11
Floppies can be simple or double-sided. However, current code was only taking the common case into account (ie 2 sides). This repairs single-sided floppies, which where totally broken before this patch : for track > 0, wrong sector number was calculated, and data was read/written at wrong place on underlying device. Fortunately, only some 360 kB floppies are single-sided, so this bug was probably not seen much. Signed-off-by: Hervé Poussineau <hpoussin@reactos.org> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2012-02-29memory: support stateless memory listenersAvi Kivity1-0/+16
Current memory listeners are incremental; that is, they are expected to maintain their own state, and receive callbacks for changes to that state. This patch adds support for stateless listeners; these work by receiving a ->begin() callback (which tells them that new state is coming), a sequence of ->region_add() and ->region_nop() callbacks, and then a ->commit() callback which signifies the end of the new state. They should ignore ->region_del() callbacks. Signed-off-by: Avi Kivity <avi@redhat.com>

2012-02-28qxl: add optinal 64bit vram barGerd Hoffmann2-7/+51
This patch adds an 64bit pci bar for vram. It is turned off by default. It can be enabled by setting the size of the 64bit bar to be larger than the 32bit bar. Both 32bit and 64bit bar refer to the same memory. Only the first part of the memory is available via 32bit bar. The intention is to allow large vram sizes for 64bit guests, by allowing the vram bar being mapped above 4G, so we don't have to squeeze it into the pci I/O window below 4G. With vram_size_mb=16 and vram64_size_mb=256 it looks like this: 00:02.0 VGA compatible controller: Red Hat, Inc.

2012-02-27usb: Resolve warnings about unassigned bus on usb device creationJan Kiszka6-27/+18
When creating an USB device the old way, there is no way to specify the target bus. Thus the warning issued by usb_create makes no sense and rather confuses our users. Resolve this by passing a bus reference to the usbdevice_init handler and letting those handlers forward it to usb_create.

2012-02-27usb-ehci: Handle ISO packets failing with an error other then NAKHans de Goede1-3/+19
Before this patch the ehci code was not checking for any other errors other then USB_RET_NAK. This causes 2 problems: 1) Other errors are not reported to the guest. 2) When transactions with the ITD_XACT_IOC bit set completing with another error would not result in USBSTS_INT getting set. I hit this problem when unplugging devices while iso data was streaming from the device to the guest. When this happens it takes a while for the guest to process the unplugging and remove ISO transactions from the ehci schedule, in the mean time these transactions would complete with a result of USB_RET_NODEV, which was not handled. This lead to the Linux guest's usb subsystem "hanging", that is it would no longer see new usb devices getting plugged in and running for example lsusb would lead to a stuck (D state) lsusb process. This patch fixes this. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-02-27usb-desc: fix user trigerrable segfaults (!config)Alon Levy1-3/+17
Check for dev->config being NULL in two places: USB_REQ_GET_CONFIGURATION and USB_REQ_GET_STATUS. The behavior of USB_REQ_GET_STATUS is unspecified in the Default state, that corresponds to dev->config being NULL (it defaults to NULL and is reset whenever a SET_CONFIGURATION with value 0, or attachment). I implemented it to correspond with the state before ed5a83ddd8c1d8ec7b1015315530cf29949e7c48, the commit moving SET_STATUS to usb-desc; if dev->config is not set we return whatever is in the first configuration. The behavior of USB_REQ_GET_CONFIGURATION is also undefined before any SET_CONFIGURATION, but here we just return 0 (same as specified for the Address state). A win7 guest failed to initialize the device before this patch, segfaulting when GET_STATUS was called with dev->config == NULL. With this patch the passthrough device still doesn't work but the failure is unrelated. Signed-off-by: Alon Levy <alevy@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-02-27qxl: make qxl_render_update asyncAlon Levy3-31/+144
RHBZ# 747011 Removes the last user of QXL_SYNC when using update drivers that use the _ASYNC io ports. The last user is qxl_render_update, it is called both by qxl_hw_update which is the vga_hw_update_ptr passed to graphic_console_init, and by qxl_hw_screen_dump. At the same time the QXLRect area being passed to the red_worker thread is passed as a copy, as part of the QXLCookie. The implementation uses interface_update_area_complete with a bh to make sure dpy_update and qxl_flip are called from the io thread, otherwise the vga->ds->surface.data can change under our feet. With this patch sdl+spice works fine. But spice by itself doesn't produce the expected screendumps unless repeated a few times, due to ppm_save being called before update_area (rendering done in spice server thread) having a chance to complete. Fixed by next patch, but see commit message for problem introduced by it. Signed-off-by: Alon Levy <alevy@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
