2013-07-29target-xtensa: avoid double-stopping at breakpointsMax Filippov
env->exception_taken is set every time an exception is taken. It is used to allow single-stepping to stop at the first exception handler instruction. This however must exclude debug exceptions, as otherwise first step from the instruction where breakpoint was hit stops at that same instruction. Also don't check env->exception_taken directly from the gen_intermediate_code_internal, instead allocate and use TB flag XTENSA_TBFLAG_EXCEPTION. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

2013-07-29xen_disk: support "direct-io-safe" backend optionStefano Stabellini
Support backend option "direct-io-safe". This is documented as follows in the Xen backend specification: * direct-io-safe * Values: 0/1 (boolean) * Default Value: 0 * * The underlying storage is not affected by the direct IO memory * lifetime bug. See: * http://lists.xen.org/archives/html/xen-devel/2012-12/msg01154.html * * Therefore this option gives the backend permission to use * O_DIRECT, notwithstanding that bug. * * That is, if this option is enabled, use of O_DIRECT is safe, * in circumstances where we would normally have avoided it as a * workaround for that bug. This option is not relevant for all * backends, and even not necessarily supported for those for * which it is relevant. A backend which knows that it is not * affected by the bug can ignore this option. * * This option doesn't require a backend to use O_DIRECT, so it * should not be used to try to control the caching behaviour. Also, BDRV_O_NATIVE_AIO is ignored if BDRV_O_NOCACHE, so clarify the default flags passed to the qemu block layer. The original proposal for a "cache" backend option has been dropped because it was believed too wide, especially considering that at the moment the backend doesn't have a way to tell the toolstack that it is capable of supporting it.

2013-07-28pflash_cfi01: duplicate status byte from bits 23:16 for 32bit readsPaul Burton
The firmware commonly used with MIPS Malta boards (YAMON) reads the status of the pflash with a 32bit memory access. On real hardware this results in the status byte being mirrored in the upper 16 bits of the read value. For example if the status byte is represented by SS then the hardware reads 0x00SS00SS. The YAMON firmware compares the status against 32bit values expecting the mirrored value and fails without it.

2013-07-28mips_malta: generate SMBUS EEPROM dataPaul Burton
The malta contains 2 EEPROMs, one containing SPD data for the SDRAM and another containing board information such as serial number and MAC address. These are both exposed via the PIIX4 SMBUS. Generating this data and providing it to smbus_eeprom_init will allow YAMON to read a serial number for the board and prevent it from warning that the EEPROM data is invalid. We already have the contents of the SPD EEPROM which are exposed via FPGA I2C accesses, this is provided as part of the SMBUS EEPROM data too for consistency.

2013-07-28mips_malta: generate SPD EEPROM data at runtimePaul Burton
The SPD EEPROM specifies the amount of memory present in the system and thus its correct contents can only be known at runtime. Calculating parts of the data on init allows the data to accurately reflect the amount of target memory present and allow YAMON to boot with an arbitrary amount of SDRAM. Where possible the SPD data will favor indicating 2 banks of SDRAM rather than 1. For example the default 128MB of target memory will be represented as 2x64MB banks rather than 1x128MB bank. This allows versions of MIPS BIOS code (such as YAMON 2.22 and older) to boot despite a bug preventing them from handling a single bank of SDRAM with the Galileo GT64120 system controller emulated by QEMU.

2013-07-28mips_malta: correct reading MIPS revision at 0x1fc00010Paul Burton
Rather than modifying the BIOS code at its original location, copy it for the 0x1fc00000 region & modify the copy. This means the original ROM code is correctly readable at 0x1e000010 whilst the MIPS revision is readable at 0x1fc00010. Additionally the code previously operated on target memory which would later be overwritten by the BIOS image upon CPU reset if the -bios argument was used to specify the BIOS image. This led to the written MIPS revision being lost. Copying using rom_copy when -bios is used fixes this issue.

2013-07-28mips_malta: fix BIOS endianness swappingPaul Burton
If the target is little endian (mipsel) then the BIOS image endianness is swapped so that the big endian BIOS binaries commonly produced can be loaded correctly. When using the -bios argument the BIOS is loaded using load_image_targphys, however this doesn't perform the load to target memory immediately. Instead it loads the BIOS file into a struct Rom which will later be written to target memory upon reset. However the endianness conversion was being performed before this, on init, and operating on the target memory which at this point is blank & will later be overwritten by the (big endian) BIOS image. Correct this by operating on the data referenced by struct Rom rather than the target memory when the -bios argument is used.

2013-07-28target-mips: fix branch in likely delay slot tcg assertJames Hogan
When a branch delay slot contains another branch instruction, the code generated raises an exception, however since is_branch==1, handle_delay_slot() doesn't get called immediately. This means ctx->bstate isn't set to BS_BRANCH, and the decoder continues decoding until a non-branch instruction is found. If the first branch was a branch likely instruction then each instruction after it generates code for the unlikely case, to go to the next tb starting after the delay slot. This results in multiple goto_tb tcg ops being generated with the same exit number. When debug is enabled this hits: tcg-op.h:2589: tcg_gen_goto_tb: Assertion `(tcg_ctx.goto_tb_issue_mask & (1 << idx)) == 0' failed. This is fixed by removing is_branch entirely, and calling handle_delay_slot() if (ctx.hflags & MIPS_HFLAG_BMASK) was set prior to the current instruction being decoded. This still prevents handle_delay_slot() being called immediately after a branch but allows it to still be called after a branch within a delay slot.
