This is setting the stage for a cleanup of FPREM and FPREM1 helpers while being sure that they behave same as bare metal. The test constructs operands using combinations of corner cases for the floating-point bitfields and prints operands, result and FPU status word for FPREM and FPREM1. The outputs can then be compared between bare metal and QEMU. The 'run-test-i386-fprem' make target does just that.

Keep saving display surface parameters at init and using these cached values instead of getting them when needed. Not sure why this is needed (maybe due to the interaction with the vga device) but not doing this broke the Xorg vmware driver at least.

Since 0b57e287, cpu_memory_rw_debug already triggers a TB invalidation. As it doesn't (and cannot) set is_cpu_write_access=1 but "consumes" the currently executed TB, the tb_invalidate_phys_page_range call from patch_instruction didn't work anymore. Fix this by open-coding the required bits to restore the CPU state from the current TB position before patching and resume execution on the patched instruction afterward.

mmu access looks something like: <check tlb> if miss goto slow_path <fast path> done: ... ; end of the TB slow_path: <pre process> mr r3, r27 ; move areg0 to r3 ; (r3 holds the first argument for all the PPC32 ABIs) <call mmu_helper> b $+8 .long done <post process> b done On ppc32 <call mmu_helper> is: (SysV and Darwin) mmu_helper is most likely not within direct branching distance from the call site, necessitating a. moving 32 bit offset of mmu_helper into a GPR ; 8 bytes b. moving GPR to CTR/LR ; 4 bytes c. (finally) branching to CTR/LR ; 4 bytes r3 setting - 4 bytes call - 16 bytes dummy jump over retaddr - 4 bytes embedded retaddr - 4 bytes Total overhead - 28 bytes (PowerOpen (AIX)) a. moving 32 bit offset of mmu_helper's TOC into a GPR1 ; 8 bytes b. loading 32 bit function pointer into GPR2 ; 4 bytes c. moving GPR2 to CTR/LR ; 4 bytes d. loading 32 bit small area pointer into R2 ; 4 bytes e. (finally) branching to CTR/LR ; 4 bytes r3 setting - 4 bytes call - 24 bytes dummy jump over retaddr - 4 bytes embedded retaddr - 4 bytes Total overhead - 36 bytes Following is done to trim the code size of slow path sections: In tcg_target_qemu_prologue trampolines are emitted that look like this: trampoline: mfspr r3, LR addi r3, 4 mtspr LR, r3 ; fixup LR to point over embedded retaddr mr r3, r27 <jump mmu_helper> ; tail call of sorts And slow path becomes: slow_path: <pre process> <call trampoline> .long done <post process> b done call - 4 bytes (trampoline is within code gen buffer and most likely accessible via direct branch) embedded retaddr - 4 bytes Total overhead - 8 bytes In the end the icache pressure is decreased by 20/28 bytes at the cost of an extra jump to trampoline and adjusting LR (to skip over embedded retaddr) once inside.

According to the documentation drivers using this device should read FB_SIZE before enabling the device to know what memory to map. This would not work if we return 0 before enabled. The docs also mention reading SVGA_REG_DEPTH but not writing it. (Only SVGA_REG_BITS_PER_PIXEL can be written but we don't really support that either.)

Commit ac4119c0 (chardev: Use timer instead of bottom-half to postpone open event, 2012-10-12) moved the alarm timer initialization to an earlier point but failed to consider that it depends on qemu_init_main_loop. Later, commit 1c53786f (vl: init main loop earlier, 2012-10-30) fixed this, but left -daemonize in two different ways. First, timers need to be reinitialized after forking. Second, the global mutex was being held by the parent, and thus dropped after forking. The first is now fixed using pthread_atfork. For the second part, make sure that the global mutex is not taken before daemonization, and similarly delay qemu_thread_self.

This will never happen right now (the assertion would fail). The next patch will set the socket or pipe in non-blocking mode, thus enabling this part of the code. Coroutines can just stop whenever they want with qemu_coroutine_yield. As soon as select tells the main loop that the migration stream is readable, the coroutine is re-entered directly in qemu_get_buffer, where it will read more data and pass it to the loading routines.
