* [MIPS] Add Goldfish target supportBhanu Chetlapalli2012-06-073-0/+324
| | | | | | | | | | | | | | | | | | | | | | Basic Goldfish support for MIPS. Also, Fix host CPU consumption when guest is idle When the CPU is in wait state, do not wake-up if an interrupt can't be taken. This avoid host CPU running at 100% if a device (e.g. timer) has an interrupt line left enabled. Also factorize code to check if interrupts are enabled in cpu_mips_hw_interrupts_pending(). CPU consumption based on a patch from Edgar E.

| * Add qemu pipe access with parameterJiang, Yunhong2012-04-072-2/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following changes are crucial for GPU H/W acceleration because some graphics applications like games perform very frequent QEMU pipe operations to send GLES commands to the host translator. For each read/write buffer operation, currently QEMU pipe requires five MMIO operations. This causes significant overhead when running with hardware virtualization enabled (e.g. HAXM) because each MMIO causes expensive transition from the guest kernel to the kernel driver, and to the QEMU user space in the end. Among such five MMIO accesses, four of them are required to just set up the parameters for the access, like the buffer address, length etc. By passing a buffer containing such parameters, we need only one MMIO operation to send a GLES command to the host translator. Update the qemu_pipe save version for pipe struct changes.

* Fix emulator crash restoring pipes from snapshotJesse Hall2012-01-091-1/+1

| | | | | | | | | | | | | | | - Add snapshot load/save support to QEMU Pipes This adds the ability to save and load QEMU Pipe connections with snapshots.

* Scrap IRQs for x86 system image.Vladimir Chtchetkine2011-10-241-0/+14
| | | | | | | | | | | | This is a temporary fix that enables GoogleTV emulation on tools R15+ The permanent solution would be to increase number of available IRQs from 16 to something more appropriate. For now just: 1. Use IRQ3 for the events device. 2. Decrease number of TTY ports from 4 to 2. These two measures would free up 3 IRQs, so the chances of running out of available IRQs are significantly decreased. Change-Id: Ie788880935d6e15f1f02f61e862c8727c8690b4a

* Fix QEMU pipe on KVMVladimir Chtchetkine2011-09-271-2/+17
| | | | | | | | | The issue was that CPU registers (CR3 in particular) in QEMU were out of sync with KVM at the time when virtual address to physical address translation was performed. This caused translation failure, and the subsequent crash. The fix was to explicitly sync QEMU registers with KVM registers just before calling VA->PA translation.

* Accelerate nand device in virtualization environmentJiang Yunhong2011-09-132-2/+50
| | | | | | | | | | | | | | | | | | | | | Currently NAND device driver need 8 MMIO access for goldfish nand device access. MMIO access is expensive in virtualization environment because each MMIO access will cause a context switch from in-kernel module to qemu user space process. Through introducing a new batch command, these multiple MMIO access can be combined into one, thus improve virtualization perofrmance. The booting time in KVM environment is reduced from 25~26 seconds to 20~21 seconds. A kernel patch is required to utilize this new batch command. The patched kernel will detect the batch support through a new flags in goldfish nand device, while current kernel is not impacted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The name of the emulated charmap must be passed to the guest kernel because it is used by the guest input handling code to load the proper charmap files from the system partition.

The only reason to change the default value would be if emulating a guest system image that depends on a different charmap during emulation. Change-Id: If571684000b159ae9e9849661c9ff18e19b4cc75

* target-arm: integrate upstream ARM translator.David 'Digit' Turner2011-06-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new translator has the following benefits: - faster emulation of ARMv5TE code (through improved JIT) - proper support for ARMv7 and NEON - rebuilding the full-eng platform images for ARMv7-A results in additionnal speed increases (a.k.a. Thumb-2 rocks!). Note that, as an interesting side effect, NEON machine code is generally slower than the equivalent C code it is supposed to replace when run inside the emulator. This can be explained by the fact that for now the translator simply translates each NEON instruction into a series of sequential host instructions (and also requires over-head for packing/unpacking/saturation/ etc...). This change has been tested by running the "full-eng" platform image rebuilt for ARMv7-A and Neon and using an appropriate kernel image (prebuilt/android-arm/kernel/kernel-qemu-armv7). The system could boot and seems to work perfectly. Not a single issue has been experienced during testing. On a 2.4 GHz Xeon CPU, the image boots in about 25 seconds (compared to 40 seconds for a vanilla one without this emulator patch). Thanks to Peter Maydell at Linaro and ARM with his hard work to make this happen (first in upstream, and now on Android). This integration is based on the Meego git repository (git://gitorious.org/qemu-maemo/qemu.git) using the following hash: 7e2d65b0c95c865b1fa6d3d4948e8e822b9ac2fd On top of which, the following upstream patch has been applied (with recommendation from Peter): b7fa9214d8d4f57992c9acd0ccb125c54a095f00 (We chose this repository because it was the closest to the previous integrate. We will probably use the Linaro ones for future work on this part of the emulator). Change-Id: I54837e3d2e908b2380d158411d7a9813630e7e4e

* New goldfish_pipe virtual device.David 'Digit' Turner2011-04-284-614/+996
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new virtual hardware device named "goldfish_pipe" used to implement a very fast communication channel between the guest system and the emulator. IMPORTANT: This depends on a special kernel driver, see: https://review.source.android.com/#change,22496 Usage from the guest is simply the following: fd = open("/dev/qemu_pipe", O_RDWR); const char* pipename = "pipe:<name>"; ret = write(fd, pipename, strlen(pipename)+1); if (ret < 0) { /* could not connect to service named <name> */ } /* now you can read()/write()/close() as a normal * file descriptor to exchange data with the service. */ In addition, this implements the following pipe services in the emulator: tcp:<port> tcp:<hostname>:<port> unix:<path> opengles The 'tcp:' and 'unix:' services simply redirect to a TCP or Unix socket on the host with minimal The 'opengles' service simply connects to tcp:locahost:22468 for now. We may change this to be more configurable in the future, but that's the port number used by the current experimental OpenGL ES hardware emulation host libraries / programs. Benchmarking with a simple ping-pong program shows that the guest <-> emulator can achieve a roundtrip bandwidth of 192 MB/s (on a 2.7 Ghz Xeon PC). Using the tcp: service to talk to a ping-pong server listening on localhost reaches 102 MB/s on the same machine, using a Unix socket reaches 140 MB/s. By contrast, using standard sockets in the guest reaches only 3.8 MB/s on the same machine (and requires special privileges from the application anyway).
