2011-07-30Add TCG optimizations stubKirill Batuzov
Added file tcg/optimize.c to hold TCG optimizations. Function tcg_optimize is called from tcg_gen_code_common. It calls other functions performing specific optimizations.

2011-07-30exec.h cleanupBlue Swirl
Move softmmu_exec.h include directives from target-*/exec.h to target-*/op_helper.c. Move also various other stuff only used in op_helper.c there. Define global env in dyngen-exec.h. For i386, move wrappers for segment and FPU helpers from user-exec.c to op_helper.c. Implement raise_exception_err_env() to handle dynamic CPUState. Move the function declarations to cpu.h since they can be used outside of op_helper.c context. LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and env_to_regs(). ARM: make raise_exception() static. Convert #include "exec.h" to #include "cpu.h" #include "dyngen-exec.h" and remove now unused target-*/exec.h. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-07-30revamp acpitable parsing and allow to specify complete (headerful) tableMichael Tokarev
This patch almost rewrites acpi_table_add() function (but still leaves it using old get_param_value() interface). The result is that it's now possible to specify whole table (together with a header) in an external file, instead of just data portion, with a new file= parameter, but at the same time it's still possible to specify header fields as before. Now with the checkpatch.pl formatting fixes, thanks to Stefan Hajnoczi for suggestions, with changes from Isaku Yamahata, and with my further refinements.

2011-07-30sd: do not add one sector to the disk sizeVincent Palatin
This leads to random off-by-one error. When the size of the SD is exactly 1GB, the emulation was returning a wrong SDHC CSD descriptor. Signed-off-by: Vincent Palatin <vpalatin@chromium.org> Signed-off-by: Andrzej Zaborowski <andrew.zaborowski@intel.com>
2011-07-30user: Restore debug usage message for '-d ?' in user mode emulationPeter Maydell
The code which prints the debug usage message on '-d ?' for *-user has to come before the check for "not enough arguments", so that "qemu-foo -d ?" prints the list of possible debug log items rather than the generic usage message.

2011-07-30hw/onenand: program actions can only clear bitsJuha Riihimäki
The program actions onenand_prog_main() and onenand_prog_spare() can only set bits. This implies a rewrite of onenand_erase() to not use the program functions, since erase does need to set bits.

2011-07-30onenand: Handle various ID fields separatelyJuha Riihimäki
Handle the manufacturer, device and version IDs separately rather than smooshing them all together into a single uint32_t. Note that the ID registers are actually 16 bit, even though typically the top bits are 0 and the Read Identification Data command only returns the bottom 8 bits.

2011-07-30lm832x: Take DeviceState pointer in lm832x_key_event()Peter Maydell
Since lm832x has been qdev'ified, its users will generally have a DeviceState pointer rather than an i2c_slave pointer, so adjust lm832x_key_event's prototype to suit. This allows the n810 (its only user) to actually pass a correct pointer to it rather than NULL. The effect is that we no longer segfault when a key is pressed.

It's already allowed by the example; there are about 1800 instances in the tree; and disallowing it would lead to if (a) { ... } else { if (b) { ... } else { if (c) { ... } else { if (d) { ... } else { ... } } } } instead of if (a) { ... } else if (b) { ... } else if (c) { ... } else if (d) { ... } else { ... } which is more readable.

2011-07-29multiboot: Fix bss segment supportGöran Weinholt
Multiboot images can specify a bss segment. The boot loader must clear the memory of the bss and ensure that no modules or structures are allocated inside it. Several fields are provided in the Multiboot header that were previously not used properly. The header is now used to determine how much data should be read from the image and how much memory should be reserved to the bss segment.

Most definitions in softfloat.h are really target-independent, but the file is not because it includes definitions of the default NaN values.

2011-07-29showing a splash picture when startwayne
Added options to let qemu transfer two configuration files to bios: "bootsplash.bmp" and "etc/boot-menu-wait", which could be specified by command -boot splash=P,splash-time=T P is jpg/bmp file name or an absolute path, T have a max value of 0xffff, unit is ms. With these two options, if user invoke qemu with menu=on option, then a splash picture would be showed in a given time. For example: qemu -boot menu=on,splash=/root/boot.bmp,splash-time=5000 would make boot.bmp shown as a brand with 5 seconds in the booting up process.
