In the case where the console does not have gl capability, and if blob is set to true, make sure that the display updates still work. Commit e86a93f55463 accidentally broke this by misplacing the return statement (in resource_flush) causing the updates to be silently ignored.

2023-01-18bulk: Rename TARGET_FMT_plx -> HWADDR_FMT_plxPhilippe Mathieu-Daudé
The 'hwaddr' type is defined in "exec/hwaddr.h" as: hwaddr is the type of a physical address (its size can be different from 'target_ulong'). All definitions use the 'HWADDR_' prefix, except TARGET_FMT_plx: $ fgrep define include/exec/hwaddr.h #define HWADDR_H #define HWADDR_BITS 64 #define HWADDR_MAX UINT64_MAX #define TARGET_FMT_plx "%016" PRIx64 ^^^^^^ #define HWADDR_PRId PRId64 #define HWADDR_PRIi PRIi64 #define HWADDR_PRIo PRIo64 #define HWADDR_PRIu PRIu64 #define HWADDR_PRIx PRIx64 #define HWADDR_PRIX PRIX64 Since hwaddr's size can be *different* from target_ulong, it is very confusing to read one of its format using the 'TARGET_FMT_' prefix, normally used for the target_long / target_ulong types: $ fgrep TARGET_FMT_ include/exec/cpu-defs.h #define TARGET_FMT_lx "%08x" #define TARGET_FMT_ld "%d" #define TARGET_FMT_lu "%u" #define TARGET_FMT_lx "%016" PRIx64 #define TARGET_FMT_ld "%" PRId64 #define TARGET_FMT_lu "%" PRIu64 Apparently this format was missed during commit a8170e5e97 ("Rename target_phys_addr_t to hwaddr"), so complete it by doing a bulk-rename with: $ sed -i -e s/TARGET_FMT_plx/HWADDR_FMT_plx/g $(git grep -l TARGET_FMT_plx) Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Message-Id: <20230110212947.34557-1-philmd@linaro.org> [thuth: Fix some warnings from checkpatch.pl along the way] Signed-off-by: Thomas Huth <thuth@redhat.com>

2023-01-11hw/display: avoid creating empty loadable modulesDaniel P. Berrangé
When using --disable-virglrenderer, QEMU still creates hw-display-virtio-gpu-gl.so hw-display-virtio-vga-gl.so hw-display-virtio-gpu-pci-gl.so but when these are loaded, they provide no functionality as the code which registers types is not compiled in. Funtionally this is relatively harmless, because QEMU is fine loading a module with no types. This is rather confusing for users and OS distro maintainers though, as they think they have the GL functionality built, but in fact the module they are looking at provides nothing of value. The root cause is the use of 'when/if_true' rules when adding sources to the module source set. If all the rules evaluate to false, then we have declared the module, but not added anything to it. We need to put declaration of the entire module inside a condition based on existance of the 3rd party library deps that are mandatory.

2023-01-08include/hw/pci: Split pci_device.h off pci.hMarkus Armbruster
PCIDeviceClass and PCIDevice are defined in pci.h. Many users of the header don't actually need them. Similar structs live in their own headers: PCIBusClass and PCIBus in pci_bus.h, PCIBridge in pci_bridge.h, PCIHostBridgeClass and PCIHostState in pci_host.h, PCIExpressHost in pcie_host.h, and PCIERootPortClass, PCIEPort, and PCIESlot in pcie_port.h. Move PCIDeviceClass and PCIDeviceClass to new pci_device.h, along with the code that needs them. Adjust include directives. This also enables the next commit.

It seems a little bit weird that the para-virtualized x86 VMWare devices "vmware-svga" and "vmxnet3" also show up in non-x86 targets. They are likely pretty useless there (since the guest OSes likely do not have any drivers for those enabled), so let's change this and only enable those devices by default for the classical x86 targets.

2022-11-07acpi: pc: vga: use AcpiDevAmlIf interface to build VGA device descriptorsIgor Mammedov
NB: We do not expect any functional change in any ACPI tables with this change. It's only a refactoring. NB2: Some targets (or1k) do not support acpi and CONFIG_ACPI is off for them. However, modules are reused between all architectures so CONFIG_ACPI is on. For those architectures, dummy stub function definitions help to resolve symbols. This change uses more of these and so it adds a couple of dummy stub definitions so that symbols for those can be resolved.

In the case that exec' function get invoked, such as the live-update feature which is been developing, it will cause fd leaks.

2022-07-28vga: fix incorrect line height in 640x200x2 modePaolo Bonzini
When in CGA modes, QEMU wants to ignore the maximum scan field (bits 0..4) of the maximum scan length register in the CRTC. It is not clear why this is needed---for example, Bochs ignores bit 7 instead. The issue is that the CGA modes are not detected correctly, and in particular mode 6 results in multi_scan==3 according to how SeaBIOS programs it. The right way to check for CGA graphics modes is to check whether bit 13 of the address is special cased by the CRT controller to achieve line interleaving, i.e. whether bit 0 of the CRTC mode control register is clear.

This patch fixes the dedicated framebuffer mailbox interface by removing an unneeded offset. This means that we pick the framebuffer address in the same way that we do if the guest code uses the buffer allocate mechanism of the bcm2835_property interface (case 0x00040001: /* Allocate buffer */ in bcm2835_property.c). The documentation of this mailbox interface doesn't say anything about using parts of the request buffer address to affect the chosen framebuffer address: https://github.com/raspberrypi/firmware/wiki/Mailbox-framebuffer-interface Some baremetal applications like the Screen01/Screen02 examples from Baking Pi tutorial[1] didn't work before this patch.

2022-06-30hw/i2c: add asynchronous sendKlaus Jensen
Add an asynchronous version of i2c_send() that requires the slave to explicitly acknowledge on the bus with i2c_ack(). The current master must use the new i2c_start_send_async() to indicate that it wants to do an asynchronous transfer. This allows the i2c core to check if the target slave supports this or not. This approach relies on adding a new enum i2c_event member, which is why a bunch of other devices needs changes in their event handling switches.
