The SDL_SetVideoMode() error condition is easily triggered by a user by simply configure a guest with a host unsupported display resolution and attempting to enable fullscreen. Since the error is fatal, adding a bit of debugging help can't harm. Sample output with this change: (qemu) Could not open SDL display (1280x1024x32): No video mode large enough for 1280x1024 The width x height might seem redundant as SDL also provides it in SDL_GetError(), but I believe there are situations where it is useful. I.e. if there is some other SDL error. Anyway, redundant information in fatal error messages has never harmed a single gerbil.

QEMU uses a fixed page size for the CPU TLB. If the guest uses large pages then we effectively split these into multiple smaller pages, and populate the corresponding TLB entries on demand. When the guest invalidates the TLB by virtual address we must invalidate all entries covered by the large page. However the address used to invalidate the entry may not be present in the QEMU TLB, so we do not know which regions to clear. Implementing a full vaiable size TLB is hard and slow, so just keep a simple address/mask pair to record which addresses may have been mapped by large pages. If the guest invalidates this region then flush the whole TLB. Signed-off-by: NPaul Brook <paul@codesourcery.com>

While there, improve the params help text.

In the human monitor, it declares a single optional argument to be parsed according to the QemuOptsList given by its name. In QMP, it declares an optional argument for each member of the QemuOptsList. Restriction: only lists with empty desc are supported for now. Good enough for the job at hand. We'll lift the restriction when we need that.

Next commit wants to use it.

We sometimes permit omitting the first option name, for example -device foo is short for -device driver=foo. The name to use ("driver" in the example) is passed as argument to qemu_opts_parse(). For each QemuOptsList, we use at most one such name. Move the name into QemuOptsList, and pass whether to permit the abbreviation. This ensures continued consistency, and simplifies the commit after next in this series.

The functions are somewhat restricted. Good enough for the job at hand. We'll extend them when we need more.

Conversion to QObject is still missing.

This reverts commit 3ced9f7a. The next commit will convert all of qdev_device_add() to QError, and it'll be clearer with this partial conversion reverted.

Treat multiple successive slashes as a one slash. Ignore trailing slashes. This is how POSIX pathnames work.

While fully converted handlers are not supposed to print anything when running in a QMP monitor, they are free to print in a human monitor. For instance, device_add (not yet converted) prints help, and will continue to do so after conversion. Moreover, utility functions converted to QError should remain usable from unconverted handlers. Two problems: * handler_audit() complains when a converted handler prints. Limit that to QMP monitors. * With QMP, handlers need to pass the error object by way of monitor_set_error(). However, we do that both for QMP and for the human monitor. The human monitor prints the error object after the handler returns. If the handler prints anything else, that output "overtakes" the error message. Limit use of monitor_set_error() to QMP monitors. Update handler_audit() accordingly.

Users can't set them, so qdev_device_help() shouldn't list them. Fix that. Also make qdev_prop_parse() hide them instead of printing a meaningless "has no parser" error message. Their value means nothing to users, so qdev_print_props() shouldn't print it. Fix by removing their print method. Their only use is dirty hacks. Document that.

Users can't create them, so qdev_device_help() shouldn't list them. Fix that. Also make qdev_device_add() pretend they don't exist. Before, it rejected them with a "can't be added via command line" message, which wasn't quite right for monitor command device_add.

To make it obvious that -device and device_add can't die in hw_error().

"device_add isa-serial,bus=pci.0" kills QEMU. Not good.

New LOC_CMDLINE. Use it for tracking option with argument in lookup_opt(). We now report errors like this qemu: -device smbus-eeprom: Did not find I2C bus for smbus-eeprom

New LOC_FILE. Use it for tracking file name and line number in qemu_config_parse(). We now report errors like qemu:foo.conf:42: Did not find I2C bus for smbus-eeprom In particular, gems like this message: -device: no driver specified become almost nice now: qemu:foo.conf:44: -device: no driver specified (A later commit will get rid of the bogus -device:)
