| * Fix SDCard speed issues too.David 'Digit' Turner2011-05-121-4/+8
|/ | | | | | | | | It looks like we also need to set the 'cache' property to 'unsafe' when initializing the SDCard block device. Otherwise it will be mounted as O_DIRECT, making all i/o operations on the SD Card extremely slow. Change-Id: Id1a72f926c73dc6981a568f005f19cfc50f724d5

| * console: Fix 'event send' handling.David 'Digit' Turner2011-05-092-4/+10
|/ | | | | | | | | | | | | | | This patch fixes two bugs in the implementation of the 'event send' command: 1/ It prevents a crash when using the '0:0:0' event triple (note that the equivalent EV_SYNC:0:0 used in testing didn't crash) 2/ If fixes the parser to correctly handle several event triples on the same line, as in: event send <type1>:<code1>:<value1> <type2>:<code2>:<value2> ...

| * Fix -snapshot-list option.David 'Digit' Turner2011-05-052-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes -snapshot-list work properly. More specifically: - If the AVD has snapshotting enabled, the emulator will find the appropriate file if you don't use -snapstorage. - If the AVD has no snapshot support, the emulator will print a user-friendly message to explain that. - If you're in the Android build, the emulator indicates that -snapstorage <file> is mandatory.

|/ | | | | | | | | | | | | | The console's 'avd name' command returned "unknown" incorrectly. This was due to a missing option when invoking the core, even in the standalone case.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QEMU is a weird animal. The "snapshot" property speeds-up snapshot saving but also redirect all stores to a temporary file which is deleted when the emulator exit. Use a different property to get the desired speed-up. Note that using "writeback" instead of "unsafe" forces the use of fdatasync() which will still be horribly slow. + Argument checking in avd snapshot commands in the console. (trying to load a name-less snapshot actually crashes the emulator). Change-Id: Ie61f110f037bbb3539c7f9892cb03bee8bfec6bd

| * | Fix snapshot save pathetic speed.David 'Digit' Turner2011-05-041-1/+6
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that the 'snapshot' property must be turned on on the block device corresponding to the snapshot storage file. Otherwise, the file is mounted O_DIRECT, which on my speedy machine limits the operation to a max of about 2.5 MB/s. This explains why saving snapshots was so pathetic. With this change, the save throughput is up to 278 MB/s on the same machine! Change-Id: I77c792114171a4ecaf3e3f08f64d8b3a30709f23

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NOTE: This integrates https://review.source.android.com/#change,21995 into the tools_r11 branch. This patch renames the current ARM-specific emulator binary to 'emulator-arm' and introduces a new tiny (less than 20KB) 'emulator' launcher program. The role of 'emulator' is to launch either 'emulator-arm' or 'emulator-x86' based on the target AVD or platform build being used. This program will be replaced in the future by what is currently known as 'emulator-ui', but is a good placeholder until this work is completed. + Move some utility functions from android/avd/info.[hc] to android/avd/util.[hc] so that 'emulator' can use them directly. IMPORTANT: For platform builds, the target architecture is detected automatically by parsing the build.prop file. For SDK AVDs however, there is no easy way to determine the target architecture, so the patch adds a new hw.cpu.arch property which can have value 'arm' or 'x86' Change-Id: Id883b67c0255b6deeae393443a1732e10ab223cb

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).

|/ | | | | | | | | | | | Starting the emulator with something like "-qemu -vnc :1" didn't result in a valid boot sequence, due to the way our "hw-control" service is initialized. This patch fixes the issue. Note however that since a VNC client cannot send proper touch events, it can only be used as a viewer at the moment. Change-Id: Ib9b60ff7028892368547bff89b84f580344c2edd

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a bug in the previous commit because the values of the android_display_width and android_display_height variables are not properly initialized when events_dev_init() is called. The variables contain their default values (640 and 480) instead of anything specific to the device's skin/emulated LCD. The result is that touch emulation doesn't work well if the screen is not exactly 640x80, because reported touch events are then incorrectly scaled. NOTE: The problem doesn't exist in the master branch, which fixed the issue with a different patch, which takes care of the core/ui separation work to do stuff the right way(TM). This adds a tools_r10-specific patch to fix the issue. Change-Id: Idc1902db5d1b2c596aadc352e62c6523922d7a20
