2012-10-20hw/pl041: Use LOG_UNIMPPeter Maydell1-2/+3
Use the new LOG_UNIMP tracing to report unimplemented features. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20hw/pl181: Use LOG_UNIMP and LOG_GUEST_ERRORPeter Maydell1-8/+10
Rather than a mix of direct printing to stderr and aborting via hw_error(), use LOG_UNIMP and LOG_GUEST_ERROR. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20hw/hw.h: Add include of qemu-log.hPeter Maydell1-0/+1
Add an include of qemu-log.h to hw.h, so that device model code has access to these logging functions without the need to directly include qemu-log.h. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20qemu-log: Add new log category for guest bugsPeter Maydell2-0/+4
Add a new category for device models to log guest behaviour which is likely to be a guest bug of some kind (accessing nonexistent registers, reading 32 bit wide registers with a byte access, etc). Making this its own log category allows those who care (mostly guest OS authors) to see the complaints without bothering most users.

2012-10-20target-sparc: Remove cpu_tmp0 as a globalRichard Henderson1-85/+118
Subroutines do their own local temporary management. Within disas_sparc_insn we limit the existance of the variable to OP=2 insns, and delay initialization as late as is reasonable for the specific XOP.

2012-10-20target-sparc: Cleanup cpu_src[12] allocationRichard Henderson1-9/+7
Now that get_temp_tl is used for get_src[12], we don't need to pre-allocate these temporaries. Fallout from this is moving some assignments around cas/casx to avoid uninitialized variable warnings. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-10-20exec: Make MIN_CODE_GEN_BUFFER_SIZE private to exec.cRichard Henderson2-2/+4
It is used nowhere else, and the corresponding MAX_CODE_GEN_BUFFER_SIZE also lives there. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20exec: Allocate code_gen_prologue from code_gen_bufferRichard Henderson2-20/+12
We had a hack for arm and sparc, allocating code_gen_prologue to a special section. Which, honestly does no good under certain cases. We've already got limits on code_gen_buffer_size to ensure that all TBs can use direct branches between themselves; reuse this limit to ensure the prologue is also reachable. As a bonus, we get to avoid marking a page of the main executable's data segment as executable. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20exec: Do not use absolute address hints for code_gen_buffer with -fpieRichard Henderson1-1/+6
The hard-coded addresses inside alloc_code_gen_buffer only make sense if we're building an executable that will actually run at the address we've put into the linker scripts. When we're building with -fpie, the executable will run at some random location chosen by the kernel. We get better placement for the code_gen_buffer if we allow the kernel to place the memory, as it will tend to to place it near the executable, based on the PROT_EXEC bit. Since code_gen_prologue is always inside the executable, this effect is easily seen at the end of most TB, with the exit_tb opcode, and with any calls to helper functions.

2012-10-20exec: Don't make DEFAULT_CODE_GEN_BUFFER_SIZE too largeRichard Henderson1-1/+5
For ARM we cap the buffer size to 16MB. Do not allocate 32MB in that case. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20exec: Split up and tidy code_gen_bufferRichard Henderson1-92/+103
It now consists of: A macro definition of MAX_CODE_GEN_BUFFER_SIZE with host-specific values, A function size_code_gen_buffer that applies most of the reasoning for choosing a buffer size, Three variations of a function alloc_code_gen_buffer that contain all of the logic for allocating executable memory via a given allocation mechanism.

2012-10-20create struct for machine initialization argumentsEduardo Habkost57-414/+518
This should help us to: - More easily add or remove machine initialization arguments without having to change every single machine init function; - More easily make mechanical changes involving the machine init functions in the future; - Let machine initialization forward the init arguments to other functions more easily. This change was half-mechanical process: first the struct was added with the local ram_size, boot_device, kernel_*, initrd_*, and cpu_model local variable initialization to all functions. Then the compiler helped me locate the local variables that are unused, so they could be removed. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-10-19qemu-options.hx: Change from recommending '?' to 'help'Peter Maydell1-21/+17
Update the -help output and documentation so that it recommends 'help' rather than '?' for the various "list valid values for this option" cases. '?' is deprecated (as it can fail confusingly if not quoted), so it's better to steer users towards 'help'. ('?' still works, for backwards compatibility.) This is the -help option part of the change otherwise done in commit c8057f9, since we are now past release 1.2 and free to change our help text without worrying about breaking libvirt.

Also, since TIGHT_PNG is the same as the TIGHT encoding but with the filter/copy replaced with PNG data, adding it to the supported encodings list when it is disabled will cause the TIGHT encoding to be used even though the client requested TIGHT_PNG.
