From 83377113bfe7791483a1b67e06dd0f51620c04ec Mon Sep 17 00:00:00 2001 From: Lioncash Date: Mon, 24 Sep 2018 20:01:45 -0400 Subject: memory: Dehardcode the use of fixed memory range constants The locations of these can actually vary depending on the address space layout, so we shouldn't be using these when determining where to map memory or be using them as offsets for calculations. This keeps all the memory ranges flexible and malleable based off of the virtual memory manager instance state. --- src/core/gdbstub/gdbstub.cpp | 15 ++++++++++----- 1 file changed, 10 insertions(+), 5 deletions(-) (limited to 'src/core/gdbstub/gdbstub.cpp') diff --git a/src/core/gdbstub/gdbstub.cpp b/src/core/gdbstub/gdbstub.cpp index 0ecdd9f82..d8c7b3492 100644 --- a/src/core/gdbstub/gdbstub.cpp +++ b/src/core/gdbstub/gdbstub.cpp @@ -37,7 +37,9 @@ #include "core/core.h" #include "core/core_cpu.h" #include "core/gdbstub/gdbstub.h" +#include "core/hle/kernel/process.h" #include "core/hle/kernel/scheduler.h" +#include "core/hle/kernel/vm_manager.h" #include "core/loader/loader.h" #include "core/memory.h" @@ -585,7 +587,8 @@ static void HandleQuery() { strlen("Xfer:features:read:target.xml:")) == 0) { SendReply(target_xml); } else if (strncmp(query, "Offsets", strlen("Offsets")) == 0) { - std::string buffer = fmt::format("TextSeg={:0x}", Memory::PROCESS_IMAGE_VADDR); + const VAddr base_address = Core::CurrentProcess()->vm_manager.GetCodeRegionBaseAddress(); + std::string buffer = fmt::format("TextSeg={:0x}", base_address); SendReply(buffer.c_str()); } else if (strncmp(query, "fThreadInfo", strlen("fThreadInfo")) == 0) { std::string val = "m"; @@ -893,11 +896,11 @@ static void ReadMemory() { static u8 reply[GDB_BUFFER_SIZE - 4]; auto start_offset = command_buffer + 1; - auto addr_pos = std::find(start_offset, command_buffer + command_length, ','); - VAddr addr = HexToLong(start_offset, static_cast(addr_pos - start_offset)); + const auto addr_pos = std::find(start_offset, command_buffer + command_length, ','); + const VAddr addr = HexToLong(start_offset, static_cast(addr_pos - start_offset)); start_offset = addr_pos + 1; - u64 len = + const u64 len = HexToLong(start_offset, static_cast((command_buffer + command_length) - start_offset)); LOG_DEBUG(Debug_GDBStub, "gdb: addr: {:016X} len: {:016X}", addr, len); @@ -906,7 +909,9 @@ static void ReadMemory() { SendReply("E01"); } - if (addr < Memory::PROCESS_IMAGE_VADDR || addr >= Memory::MAP_REGION_VADDR_END) { + const auto& vm_manager = Core::CurrentProcess()->vm_manager; + if (addr < vm_manager.GetCodeRegionBaseAddress() || + addr >= vm_manager.GetMapRegionEndAddress()) { return SendReply("E00"); } -- cgit v1.2.3
