tb_invalidate_page_range() was intended to be used to invalidate an area of a TB which the guest explicitly flushes from i-cache. However, QEMU detects writes to code areas where TBs have been generated, so his has never been useful. Delete the function, adjust callers.

The previous patch removed the need for parameter puc. Is is now unused, so remove it. Cc: Aurelien Jarno <aurelien@aurel32.net> Reviewed-by: NPeter Maydell <peter.maydell@linaro.org> Signed-off-by: NStefan Weil <weil@mail.berlios.de>

Function gen_pc_load was introduced in commit d2856f1a. The only reason for parameter searched_pc was a debug statement in target-i386/translate.c. Parameter puc was needed by target-sparc until commit d7da2a10. Remove searched_pc from the debug statement and remove both parameters from the parameter list of gen_pc_load. As the function name gen_pc_load was also misleading, it is now called restore_state_to_opc. This new name was suggested by Peter Maydell, thanks. v2: Remove last parameter, too, and rename the function. v3: Fix [] typo in target-arm/translate.c. Fix wrong SHA1 object name in commit message (copy+paste error).

Most of emulated CPU have instructions aligned on 16 or 32 bits, while on others GCC tries to align the target jump location. This means that 1/2 or 3/4 of tb_phys_hash entries are never used. Update the hash function tb_phys_hash_func() to ignore the two lowest bits of the address. This brings a 6% speed-up when booting a MIPS image. Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>

MAX_OPC_PARAM is intended to refer to the maximum number of entries used in gen_opparam_buf[] for any single helper call. It is currently defined as 10, but for 32-bit archs, the correct value (with a maximum for four helper arguments) is 14, and for 64-bit archs, only 9 entries are needed. tcg_gen_callN() fills four entries with the function address, flags, number of args, etc. and on 32-bit archs uses a further two entries per argument (with a maximum of four helper arguments), plus two more for the return value. On 64-bit archs, only half as many entries are used for the args and the return value. In reality, TBs tend not to consist purely of helper calls exceeding the stated 10 gen_opparam_buf[] entries, so this would never actually be a problem on 32-bit archs, but the definition is still rather confusing.

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>

kqemu introduces a number of restrictions on the i386 target. The worst is that it prevents large memory from working in the default build. Furthermore, kqemu is fundamentally flawed in a number of ways. It relies on the TSC as a time source which will not be reliable on a multiple processor system in userspace. Since most modern processors are multicore, this severely limits the utility of kqemu. kvm is a viable alternative for people looking to accelerate qemu and has the benefit of being supported by the upstream Linux kernel. If someone can implement work arounds to remove the restrictions introduced by kqemu, I'm happy to avoid and/or revert this patch. N.B. kqemu will still function in the 0.11 series but this patch removes it from the 0.12 series. Paul, please Ack or Nack this patch. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>
