| 156 | fix parameter-passing corruption on x86_64 for >= 5 args |
|---|
| 157 | |
|---|
| 158 | On x86_64 without HAVE_USE_MS_ABI support, uefi_call_wrapper() is a |
|---|
| 159 | variadic function. Parameters >=5 are copied to the stack and, when |
|---|
| 160 | passed small immediate values (and possibly other parameters), gcc |
|---|
| 161 | would emit a movl instruction before calling uefi_call_wrapper(). As a |
|---|
| 162 | result, only the lower 32b of these stack values are significant, the |
|---|
| 163 | upper 32b potentially contain garbage. Considering that |
|---|
| 164 | uefi_call_wrapper() assumes these arguments are clean 64b values |
|---|
| 165 | before calling the efi_callX() trampolines, the latter may be passed |
|---|
| 166 | garbage. This makes calling functions like |
|---|
| 167 | EFI_PCI_IO_PROTOCOL.Mem.Read()/Write() or BS->OpenProtocol() quite |
|---|
| 168 | unreliable. |
|---|
| 169 | |
|---|
| 170 | This patch fixes this by turning uefi_call_wrapper() into a macro that |
|---|
| 171 | allows to expose the efi_callX() trampoline signatures to the callers, |
|---|
| 172 | so that gcc can know upfront that it has to pass all arguments to |
|---|
| 173 | efi_callX() as clean 64b values (eg. movq for immediates). The |
|---|
| 174 | _cast64_efi_callX macros are just here to avoid a gcc warning, they do |
|---|
| 175 | nothing otherwise. |

|---|
| 181 | |
|---|
| 182 | - Removes the ElfW() macro usage from reloc_ia32.c and reloc_x86_64.c. These |
|---|
| 183 | macros only exist in link.h on Linux. On FreeBSD, the equivalent macro is |
|---|
| 184 | __ElfN(). But the macro usage is redundant. You're only going to compile the |
|---|
| 185 | ia32 file for IA32 binaries and the x86_64 file for X64 binaries. If you had |
|---|
| 186 | just one file built for both cases, then using the macro might make more |
|---|
| 187 | sense. |
|---|
| 188 | |
|---|
| 189 | - Removes the "#define foo_t efi_foo_t" macros from reloc_ia32.c and |
|---|
| 190 | reloc_x86_64.c. |
|---|
| 191 | |
|---|
| 192 | - Modifies inc/x86_64/efibind.h and inc/ia32/efibind.h to use the new |
|---|
| 193 | definitions for uint64_t, int64_t and int8_t. The 64-bit types are now defined |
|---|
| 194 | as: |
|---|
| 195 | |
|---|
| 196 | typedef int __attribute__((__mode__(__DI__))) int64_t; |
|---|
| 197 | typedef unsigned int __attribute__((__mode__(__DI__))) uint64_t; |
|---|
| 198 | |
|---|
| 199 | This removes the conflict between the host types dragged in by elf.h and the |
|---|
| 200 | type definitions in efibind.h that made the #define foo_t efi_foo_t" hack |
|---|
| 201 | necessary. Also, int8_t is now defined as signed char instead of just char |
|---|
| 202 | (assuming char == signed char is apparently not good enough). |
|---|
| 203 | |
|---|
| 204 | - Also modifies these files to use stdint.h instead of stdint-gcc.h. It's |
|---|
| 205 | unclear if this is completely correct, but stdint-gcc.h is not present with |
|---|
| 206 | all GCC installs, and if you use -std=c99 or later you will force this case to |
|---|
| 207 | be hit. This also can break clang, which doesn't have a stdint-gcc.h at all. |
|---|
| 208 | |
|---|
| 209 | - Removes the #include of <link.h> from reloc_ia32.c and reloc_x86_64.c (since |
|---|
| 210 | with the previous changes it's not needed anymore). |
|---|
| 211 | |
|---|
| 212 | - Places the #include of <elf.h> after #include <efi>/#include <efilib.h> so |
|---|
| 213 | that we know the types will always be defined properly, in case you build on a |
|---|
| 214 | system where <elf.h> doesn't automatically pull in the right header files to |
|---|
| 215 | define all the needed types. (This actually happens on VxWorks. It's harmless |
|---|
| 216 | elsewhere. If you don't care about VxWorks, you can leave this out.) |
|---|
| 217 | |
|---|
| 218 | - Modifies setjmp_ia32.S and setjmp_x86_64.S so to change "function" to |
|---|
| 219 | @function. The clang compiler doesn't like the former. Clang and GCC both like |
|---|
| 220 | the latter. |
|---|
| 221 | |
|---|
| 222 | - Modifles Make.defaults so that if ARCH is detected as "amd64," it's changed |
|---|
| 223 | to "x86_64." It happens that uname -m on 64-bit FreeBSD reports the former |
|---|
| 224 | rather than the latter, which breaks the build. This may also be the case on |
|---|
| 225 | some other OSes. There's a way to force uname(1) to return x86_64 as the |
|---|
| 226 | machine type, but this way is a little friendlier. |
|---|
| 227 | |
|---|
| 228 | - Creates gnuefi/elf_ia32_fbsd_efi.lds which specifies the object file type as |
|---|
| 229 | elf-ia32-freebsd. This is required for building on FreeBSD/i386, not just |
|---|
| 230 | FreeBSD/amd64. |
|---|
| 231 | |
|---|
| 232 | - Modifies apps/Makefile to always use |
|---|
| 233 | $(TOPDIR)/gnuefi/elf_$(ARCH)_fbsd_efi.lds when building on either 32-bit or |
|---|
| 234 | 64-bit FreeBSD instead of just for the x86_64 case. |
|---|
| 235 | |
|---|
| 236 | - Changed LDFLAGS in Make.defaults to include --no-undefined. This will cause |
|---|
| 237 | linking to fail if there are any unsatisfied symbols when creating foo.so |
|---|
| 238 | during any of the app builds, as opposed to just silently succeeding and |
|---|
| 239 | producing an unusable binary. |
|---|
| 240 | |
|---|
| 241 | - Changed CFLAGS to include -ffreestanding -fno-stack-protector -fno-stack- |
|---|
| 242 | check. This prevents clang from inserting a call to memset() when compiling |
|---|
| 243 | the RtZeroMem() and RtSetMem() routines in lib/runtime/efirtlib.c and guards |
|---|
| 244 | against the native compiler in some Linux distros from adding in stack |
|---|
| 245 | checking code which relies on libc help that isn't present in the EFI runtime |
|---|
| 246 | environment. |
|---|
| 247 | |
|---|
| 248 | This does the following: |
|---|
| 249 | |
|---|
| 250 | - Cleans up the ia32 and x86-64 relocation code a bit (tries to break the |
|---|
| 251 | dependency between the host ELF headers and the EFI runtime environment) |
|---|
| 252 | - Avoids the dependency on stdint-gcc.h which may not always be available |
|---|
| 253 | - Allows GNU EFI to build out of the box on both FreeBSD/i386 and |
|---|
| 254 | FreeBSD/amd64 |
|---|
| 255 | - Allows GNU EFI to build out of the box with either GCC or clang on |
|---|
| 256 | FreeBSD/i386 and FreeBSD/amd64 9.0 and later. |
|---|
| 257 | - Makes things a little easier to port to VxWorks |
|---|
| 258 | - Avoids creating un-runable binaries with unresolved symbol definitions |
|---|
| 259 | (which can be very confusing to debug) |

|---|
| 273 | * Change from Peter Jones <pjones@redhat.com> |
|---|
| 274 | - Previously we were incorrectly passing 3 functions with |
|---|
| 275 | the System V ABI to UEFI functions as EFI ABI functions. |
|---|
| 276 | Mark them as EFIAPI so the compiler will (in our new |
|---|
| 277 | GNU_EFI_USE_MS_ABI world) use the correct ABI. |
|---|
| 278 | - These need to be EFIAPI functions because in some cases |
|---|
| 279 | they call ST->ConOut->OutputString(), which is an EFIAPI |
|---|
| 280 | function. (Which means that previously in cases that |
|---|
| 281 | needed "cdecl", these didn't work right.) |
|---|
| 282 | - If the compiler version is new enough, and GNU_EFI_USE_MS_ABI |
|---|
| 283 | is defined, use the function attribute ms_abi on everything |
|---|
| 284 | defined with "EFIAPI". Such calls will no longer go through |
|---|
| 285 | efi_call*, and as such will be properly type-checked. |
|---|
| 286 | - Honor PREFIX and LIBDIR correctly when passed in during the build. |
|---|
| 287 | - Add machine type defines for i386, arm/thumb, ia64, ebc, x86_64. |
|---|
| 288 | - __STDC_VERSION__ never actually gets defined unless there's a |
|---|
| 289 | --std=... line. So we were accidentally defining lots of c99 |
|---|
| 290 | types ourself. Since it's 2012, use --std=c11 where appropriate, |
|---|
| 291 | and if it's defined and we're using gcc, actually include gcc's |
|---|
| 292 | stdint definitions. |
|---|
| 293 | - New test application added: route80h. This is a test program |
|---|
| 294 | for PciIo. It routes ioport 80h on ICH10 to PCI. This is also |
|---|
| 295 | useful on a very limited set of hardware to enable use of |
|---|
| 296 | a port 80h debug card. |
|---|
| 297 | - New test applcation added: modelist. This lists video modes |
|---|
| 298 | the GOP driver is showing us. |

|---|
| 311 | BufferSize is a UINT64 *. The file shipped with GNU EFI is from |
|---|
| 312 | 1998 whereas the latest one is from 2004. I suspect Intel changed |
|---|

|---|
| 314 | * Change from Felipe Contreras <felipe.contreras@gmail.com> |
|---|
| 315 | - The current code seems to screw the stack at certain points. |
|---|
| 316 | Multiple people have complained that gummiboot hangs right away, |
|---|
| 317 | which is in part the fault of gummiboot, but happens only |
|---|
| 318 | because the stack gets screwed. x86_64 EFI already aligns the |
|---|
| 319 | stack, so there's no need for so much code to find a proper |
|---|
| 320 | alignment, we always need to shift by 8 anyway. |
|---|

|---|
| 449 | * split gnu-efi package in two different packages: the libary+include+crt and the bootloader. |
|---|
| 450 | * removed W2U() hack and related files to get from wide-char to unicode. |
|---|
| 451 | * Use -fshort-wchar option for unicode. |

|---|
| 453 | |
|---|
| 454 | 2001-04-06 Stephane Eranian <eranian@hpl.hp.com> |
|---|
| 455 | |
|---|
| 456 | * incorporated patches from David and Michael Johnston at Intel |
|---|
| 457 | to get the package to compile for IA-32 linux target. |
|---|
| 458 | |
|---|
| 459 | * Fixed ELILO to compile for Ia-32 (does not execute yet, though): |
|---|
| 460 | Makefile and start_kernel() function. |
|---|
| 461 | |
|---|
| 462 | 2001-04-06 Andreas Schwab <schwab@suse.de> |
|---|
| 463 | |
|---|
| 464 | * Fixed config.c to |
|---|
| 465 | get the timeout directive to do something. implemented the global |
|---|
| 466 | root= directive. |

| 468 | * Fix the efi_main() to deal with the -C option properly |
|---|
| 469 | |
|---|
| 470 | 2001-04-05 Stephane Eranian <eranian@hpl.hp.com> |
|---|
| 471 | |
|---|
| 472 | * update efi library to latest EFI toolkit 1.02 as distributed |
|---|
| 473 | by Intel. Fixed header + library files to compile with GCC |
|---|
| 474 | |
|---|
| 475 | * merged ELI and LILO (as of gnu-efi-1.1) together, mostly |
|---|
| 476 | taking the config file feature of ELI. |
|---|
| 477 | |
|---|
| 478 | * renamed LILO to ELILO to make the distinction |
|---|
| 479 | |
|---|
| 480 | * restructured code to make it easier to understand and maintain |
|---|
| 481 | |
|---|
| 482 | * fixed FPSWA driver checking and loading: we try all possible |
|---|
| 483 | files and let the driver itself figure out if it is the most |
|---|
| 484 | recent. |
|---|
| 485 | * added support for compression (gzip) but keep support for plain |
|---|
| 486 | ELF image. ELILO autodetects the format |
|---|
| 487 | |
|---|
| 488 | * change the way the kernel is invoked. Now we call it in |
|---|
| 489 | physical memory mode. This breaks the dependency between the |
|---|
| 490 | kernel code and the loader. No more lilo_start.c madness. |
|---|
| 491 | |
|---|
| 492 | * changed the way the boot_params are passed. We don't use the |
|---|
| 493 | ZERO_PAGE_ADDR trick anymore. Instead we use EFI runtime memory. |
|---|
| 494 | The address of the structure is passed to the kernel in r28 |
|---|
| 495 | by our convention. |
|---|
| 496 | |
|---|
| 497 | * released as gnu-efi-2.0 |
|---|
| 498 | |
|---|
| 499 | 2001-04-03 David Mosberger <davidm@hpl.hp.com> |
|---|
| 500 | |
|---|
| 501 | * gnuefi/reloc_ia32.c (_relocate): Change return type from "void" |
|---|
| 502 | to "int". Return error status if relocation fails for some |
|---|
| 503 | reason. |
|---|
| 504 | |
|---|
| 505 | * gnuefi/elf_ia32_efi.lds: Drop unneeded ".rel.reloc" section. |
|---|
| 506 | |
|---|
| 507 | * gnuefi/crt0-efi-ia32.S (_start): Exit if _relocate() returns with |
|---|
| 508 | non-zero exit status. |
|---|
| 509 | |
|---|
| 510 | * inc/ia32/efibind.h [__GNUC__]: Force 8-byte alignment for 64-bit |
|---|
| 511 | types as that is what EFI appears to be expecting, despite the |
|---|
| 512 | "#pragma pack()" at the beginning of the file! |
|---|
| 513 | |
|---|
| 514 | 2001-03-29 David Mosberger <davidm@hpl.hp.com> |
|---|
| 515 | |

|---|
| 517 | libc/efilib collision on uint64_t et al. |
|---|
| 518 | (_relocate): Use ELF32_R_TYPE() instead of ELFW(R_TYPE)(). |
|---|
| 519 | |
|---|
| 520 | * gnuefi/crt0-efi-ia32.S (dummy): Add a dummy relocation entry. |
|---|
| 521 | |

|---|
| 529 | |
|---|
| 530 | 2000-10-26 David Mosberger <davidm@hpl.hp.com> |
|---|
| 531 | |
|---|
| 532 | * gnuefi/elf_ia64_efi.lds: Mention .rela.sdata. |
|---|
| 533 | |
|---|
| 534 | * Make.defaults (CFLAGS): Remove -nostdinc flags so we can pick |
|---|
| 535 | up the C compiler's stdarg.h. |
|---|
| 536 | |
|---|
| 537 | * inc/stdarg.h: Remove this file. It's not correct for gcc (nor |
|---|
| 538 | most other optimizing compilers). |
|---|
| 539 | |
|---|
| 540 | 2000-10-10 Stephane Eranian <eranian@hpl.hp.com> |
|---|
| 541 | |
|---|
| 542 | * cleaned up the error message and printing of those. |
|---|
| 543 | * added support to load the FPSWA from a file in case support is not |
|---|
| 544 | present in the firmware already |
|---|
| 545 | * fixed split_args() to do the right thing when you have leading spaces |
|---|
| 546 | before kernel name |
|---|
| 547 | * changed the argify() function to rely on \0 instead of LoadOptionSize |
|---|
| 548 | as the field seems to be broken with current firmware |
|---|
| 549 | * bumped version to 1.0 |
|---|
| 550 | |
|---|
| 551 | 2000-10-04 David Mosberger <davidm@hpl.hp.com> |

|---|
| 595 | 100 hardcoded instead of using MAX_FUNCTION_DESCRIPTORS |
|---|
| 596 | macro. Duh. |
|---|
| 597 | |
