2010-03-14Fix corner case in chardev udp: parameterJan Kiszka1-1/+1

2010-03-14tcg: add div/rem 32-bit helpersAurelien Jarno7-2/+89
Some targets like ARM would benefit to use 32-bit helpers for div/rem/divu/remu. Create a #define for div2 so that targets can select between div, div2 and helper implementation. Use the helper version if none of the #define are present. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-03-13x86/cpuid: Enable all features of real CPUAurelien Jarno1-30/+26
Enable all features of real CPU, unsupported features will be trimmed depending on TCG or KVM capabilities. Move the list of unsupported TCG features near the TCG capabilities masks. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-03-13x86/cpuid: fix CPUID levelsAndre Przywara1-2/+2
Bump up the xlevel number for qemu32 to allow parsing of the processor name string for this model. Similiarly the 486 processor should have at least the feature bit leaf enabled. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-03-13x86/cpuid: Always expose 32 and 64-bit CPUsAndre Przywara1-2/+0
Since 64-bit capability is just another CPUID bit we now properly mask, there is no reason anymore to hide the 64-bit capable CPU models from a 32-bit only QEMU. All 64-bit CPUs can be used perfectly in 32-bit legacy mode anyway, so these models also make sense for 32-bit.

2010-03-13x86/cpuid: add TCG feature bit trimmingAndre Przywara1-0/+24
In KVM we trim the user provided CPUID bits to match the host CPU's one. Introduce a similar feature to QEMU/TCG. Create a mask of TCG's capabilities and apply it to the user bits. This allows to let the CPU models reflect their native archetypes. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-03-13x86/cpuid: remove unnecessary kvm_trim functionAndre Przywara1-21/+6
Correct me if I am wrong, but kvm_trim looks like a really bloated implementation of a bitwise AND. So remove this function and replace it with the real stuff(TM). Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-03-13x86/cpuid: add missing CPUID feature flag namesAndre Przywara1-8/+8
Some CPUID feature flags had no string value, so they could not be switched on or off from the command line. Add names for the missing ones mentioned in the current public CPUID specification from both Intel and AMD. Those only mentioned in the Linux kernel source I put as comments.

2010-03-13x86/cpuid: moved host_cpuid function and remove prototypeAndre Przywara1-37/+34
the host_cpuid function was located at the end of the file and had a prototype before it's first use. Move it up and remove the prototype. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-03-13x86/cpuid: replace magic number with named constantAndre Przywara1-5/+6
CPUID leaf Fn8000_0001.EDX contains a copy of many Fn0000_0001.EDX bits. Define a name for this mask to improve readability and avoid typos. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-03-13x86/cpuid: move CPUID functions into separate fileAndre Przywara4-1115/+1146
about half of target-i386/helper.c consist of CPUID related functions. Only one of them is a real TCG helper function. So move the whole CPUID stuff out of this into a separate file to get better maintainable parts. This is only code reordering and should not affect QEMU's functionality.

2010-03-13tcg/arm: correctly save/restore registers in prologue/epilogueAurelien Jarno1-4/+7
Since commit 6113d6d3169393c323ac4c82d756a850145a5e7a QEMU crashes on ARM hosts. This is not a bug of this commit, but a latent bug revealed by this commit. The TCG code is called through a procedure call using the prologue and epilogue code. This code does not save and restore enough registers. The "Procedure Call Standard for the ARM Architecture" says: A subroutine must preserve the contents of the registers r4-r8, r10,  r11 and SP (and r9 in PCS variants that designate r9 as v6). The current code only saves and restores r9 to r11, and misses r4 to r8. The patch fixes that by saving r4 to r12. Theoretically there is no need to save and restore r12, but an even number of registers have to be saved as per EABI. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-03-12Add tb_page_addr_tPaul Brook3-37/+52
The page tracking code in exec.c is used by both userspace and system emulation. Userspace emulation uses it to track virtual pages, and system emulation to track ram pages. Introduce a new type to hold this kind of address. Signed-off-by: Paul Brook <paul@codesourcery.com>
2010-03-12Fix last page errors in page_check_range and page_set_flags.Richard Henderson1-18/+36
The addr < end comparison prevents iterating over the last page in the guest address space; an iteration based on length avoids this problem. At the same time, assert that the given address is in the guest address space. Signed-off-by: Richard Henderson <rth@twiddle.net>
2010-03-12Implement multi-level page tables.Richard Henderson2-177/+275
Define L1_MAP_ADDR_SPACE_BITS to be either the virtual address size (in user mode) or physical address size (in system mode), and use that to size l1_map. This rewrites page_find_alloc, page_flush_tb, and walk_memory_regions. Use TARGET_PHYS_ADDR_SPACE_BITS for the physical memory map based off of l1_phys_map. This rewrites page_phys_find_alloc and phys_page_for_each. Signed-off-by: Richard Henderson <rth@twiddle.net>
2010-03-12linux-user: Fix mmap_find_vma returning invalid addresses.Richard Henderson3-33/+82
Don't return addresses that aren't properly aligned for the guest, e.g. when the guest has a larger page size than the host. Don't return addresses that are outside the virtual address space for the target, by paying proper attention to the h2g/g2h macros. At the same time, place the default mapping base for 64-bit guests (on 64-bit hosts) outside the low 4G. Consistently interpret mmap_next_start in the guest address space.

Previously, only 32-bit guests had a proper check for the validity of the virtual address. Extend that check to 64-bit guests with a restricted virtual address space. Signed-off-by: Richard Henderson <rth@twiddle.net>
2010-03-12Move TARGET_PHYS_ADDR_SPACE_BITS to target-*/cpu.h.Richard Henderson12-18/+63
Removes a set of ifdefs from exec.c. Introduce TARGET_VIRT_ADDR_SPACE_BITS for all targets other than Alpha. This will be used for page_find_alloc, which is supposed to be using virtual addresses in the first place. Signed-off-by: Richard Henderson <rth@twiddle.net>
