Log Message:
iWorkaround panic: fpudna from userland
i386 Xen PV domU get spurious fpudna traps from userland. Older eager FPU
contact switching code took care of ignoring them. When transitioning
from eager switching to awlays switching, this special handling was
removed, causing "fpudna from userland" panics.
This change restores the previosu behavior where fpudna traps from
userland are ignored on Xen PV domU.

We do not have any documentation specific to primary bootstrap. x86/boot(8) domuent the behavior with no detail about primary and secondary bootstrap distinct roles. The change makes primary bootstrap behavior in line with secondary bootstrap and with what is already documented in x86/boot(8). Hence there is no documentation update, we could consider it as a bug fix, since the previosu behavior did not match x86/boot(8) documentation. -- Emmanuel Dreyfus m...@netbsd.org

Module Name:src
Committed By: manu
Date: Thu Jun 29 14:18:58 UTC 2023
Modified Files:
src/sys/arch/i386/stand/bootxx: boot1.c
Log Message:
Primary bootstrap is now able to read a GPT inside RAIDframe.
Previously, primary bootstrap was able to boot on RAID-1 RAIDframe set
with the limitation that the FFS filesystem had to start at bloc 0 in the
RAID. That allowed inner RAID partitionning with a disklabel, but not with
a GPT.
When booting on a RAID-1 RAIDframe, primary bootstrap now first try a
filesystem at bloc 0 of the RAID as before. On failure, it tries to
read a GPT and load secondary bootstrap from, by priority;
1) the first partition with the bootme attribute set
2) the first partition of type FFS, LFS, CCD or CGD
3) the first partition present in the GPT

CVS commit: src/sys/dev/adb
Module Name:src
Committed By: manu
Date: Sat May 14 01:16:55 UTC 2022
Modified Files:
src/sys/dev/adb: adb_kbd.c adb_keymap.h adb_usb_map.c
Log Message:
Add ISO and JIS keyboard layouts for ADB to USB emulation
The layout is configurable using sysctl machdep.adbkbdX.emulate_usb:
0 = no emulation
1 = ANSI
2 = ISO (new with this change)
3 = JIS (new with this change)
Default value is detected using the ADB keyboard handler id. JIS
default is disabled until it is tested.

I recall it now.
In src/sys/arch/i386/stand/efiboot/devopen.c
bios2dev(boot_biosdev, boot_biossector, &devname, &unit,
&partition, NULL);
In the same file, bios2dev() passes NULL part_name to biosdisk_findpartition()
void
bios2dev(int biosdev, daddr_t sector, char **devname, int *unit,
int *partition, const char **part_name)
{
(...)
(void)biosdisk_findpartition(biosdev, sector, partition, part_name);
In src/sys/arch/i386/stand/lib/biosdisk.c
int
biosdisk_findpartition(int biosdev, daddr_t sector,
int *partition, const char **part_name)
{
(...)
/* default ot first partition */
*partition = 0;
*part_name = NULL;
part_name is NULL, *part_name crashes. How do you avoid that?

So far I privilegied working on a fix to the boot problem that was reported, rather than spending time on a revert. This was not a futile effort, since at this point we have a fix that we agree on. My idea was to commit it and then to address the other points you raised, but if you cannot stand that, feel free to do the revert on your own. There is also this problem that seems worth spending time to me: http://mail-index.netbsd.org/tech-kern/2020/01/02/msg025911.html I hit this bug 100% reliabily with qemu/EFI, even with the multiboot stuff removed, and it seems to match what Masanobu Saitoh reported.

That's supposed to be the naming convention. The idea is that one day if ld gets more reasonable, it could go in non-loading note ection at the beginning of the binary, but if you prefer .text, let us go with that. On the section name, ELF specification says "Section names with a dot (.) prefix are reserved for the system" (TIS ELF specification version 1.2), section names without a dot are allowed, and we use plenty of them in our kernels (e.g.: link_set_* sections). Our naming convention is not obvious to me, nor what the specification means by "the system" here. My hunch would be to avoid using an abitratry name inside a reserved namespace, althought we already did it. If you have a strong opinion on it, I can stand a leading dot in the multiboot section name. > I don't know if you realize, but you landed a huge pile > of crap in the middle of the amd64 locore I have been working on this, but the priority was obviously the boot problem.

Attached is an updated patch with this approach. I tested at mine and
it seems fine.
I am especially interested by feedback from msaitoh@ who reported the
crash at cpu attacch that I suspect to be the (probably unrelated)

I suspect this is a second bug that was undercovered by the multiboot
change. I get crashes like the one you report 100% reproductible with
qemu UEFI boot. I described the thing here:
http://mail-index.netbsd.org/tech-kern/2020/01/02/msg025911.html
Could you check with ddb the physical address accessed? Here is the
relevant excerpt in the message I posted:
db{0}> x/i $rip
netbsd:kmem_intr_alloc+0x64:movq%r12,0(%rax)
db{0}> print $rax
92057868
db{0}> call vtophys(92057868)
108
If you can add a #define DEBUG_MEMMAP 1 at the beginning of
src/sys/arch/x86/x86/efi.c and x86_machdep.c you will also have the
memory map provided by UEFI.

That works. We can even make the multiboot section a note, for the sake
on cleanliness. (see attached patch. MULTIBOOT is enabled for testing).

Any hints about the problems you encountered? Perhaps we can work it
around with an . = ALIGN(__LARGEE_PAGE_SIZE); before including .text.user ?

Sure, it's just next in the todo list.

FWIW, this is in line with how it was done on i386: it is just stored at the beginning of .text. Xen does the same. Of course it seems more natural to store that in a note section this is not loaded, but after experimenting a lot, I am not sure it can be done, since ld really want to push notes at the end of the file. -- Emmanuel Dreyfus m...@netbsd.org

Please try the attached patch. It adds the -n flag to ld, which disable auto-alignment of sections in the file. I undestand alignement is highly desirable for userland programs that may be mapped from file, but useless for the kernel, which is just readen once by the bootloader. Without auto-alignement, the .text segment starts right after the ELF headers. This means the multiboot header can go in .text and stay below 32k (as required by the multiboot specification). There is no need for a multiboot section for that, and therefore no need to modify the linker script. A side effect is that the kernel file shrinks of 2 MB, because there is not an alignement hole between ELF headers and the .text section anymore. My patch also enable the MULTIBOOT option so that we can check nothing gets broken with it. You can also try with the option disabled, of course. -- Emmanuel Dreyfus m...@netbsd.org ? sys/arch/amd64/compile/obj ? sys/arch/amd64/stand/prekern/obj Index: sys/arch/amd64/amd64/locore.S === RCS file: /cvsroot/src/sys/arch/amd64/amd64/locore.S,v retrieving revision 1.195 diff -U4 -r1.195 locore.S --- sys/arch/amd64/amd64/locore.S 15 Dec 2019 02:58:21 - 1.195 +++ sys/arch/amd64/amd64/locore.S 26 Dec 2019 16:44:10 - @@ -431,51 +431,8 @@ .size tmpstk, tmpstk - . .space 512 tmpstk: -.section multiboot,"a" -#if defined(MULTIBOOT) - .align 8 - .globl Multiboot2_Header -_C_LABEL(Multiboot2_Header): - .intMULTIBOOT2_HEADER_MAGIC - .intMULTIBOOT2_ARCHITECTURE_I386 - .intMultiboot2_Header_end - Multiboot2_Header - .int-(MULTIBOOT2_HEADER_MAGIC + MULTIBOOT2_ARCHITECTURE_I386 \ - + (Multiboot2_Header_end - Multiboot2_Header)) - - .int1 /* MULTIBOOT_HEADER_TAG_INFORMATION_REQUEST */ - .int12 /* sizeof(multiboot_header_tag_information_request) */ - /* + sizeof(uint32_t) * requests */ - .int4 /* MULTIBOOT_TAG_TYPE_BASIC_MEMINFO */ - .align 8 - - .int3 /* MULTIBOOT_HEADER_TAG_ENTRY_ADDRESS */ - .int16 /* sizeof(struct multiboot_tag_efi64) */ - .quad (multiboot2_entry - KERNBASE) - .align 8 - - .int9 /* MULTIBOOT_HEADER_TAG_ENTRY_ADDRESS_EFI64 */ - .int16 /* sizeof(struct multiboot_tag_efi64) */ - .quad (multiboot2_entry - KERNBASE) - .align 8 - -#if notyet - /* -* Could be used to get an early console for debug, -* but this is broken. -*/ - .int7 /* MULTIBOOT_HEADER_TAG_EFI_BS */ - .int8 /* sizeof(struct multiboot_tag) */ - .align 8 -#endif - - .int0 /* MULTIBOOT_HEADER_TAG_END */ - .int8 /* sizeof(struct multiboot_tag) */ - .align 8 - .globl Multiboot2_Header_end -_C_LABEL(Multiboot2_Header_end): -#endif /* MULTIBOOT */ /* * Some hackage to deal with 64bit symbols in 32 bit mode. * This may not be needed if things are cleaned up a little. @@ -2179,8 +2136,50 @@ SYSCALL_ENTRY syscall,is_svs=0 TEXT_USER_BEGIN +#if defined(MULTIBOOT) + .align 8 + .globl Multiboot2_Header +_C_LABEL(Multiboot2_Header): + .intMULTIBOOT2_HEADER_MAGIC + .intMULTIBOOT2_ARCHITECTURE_I386 + .intMultiboot2_Header_end - Multiboot2_Header + .int-(MULTIBOOT2_HEADER_MAGIC + MULTIBOOT2_ARCHITECTURE_I386 \ + + (Multiboot2_Header_end - Multiboot2_Header)) + + .int1 /* MULTIBOOT_HEADER_TAG_INFORMATION_REQUEST */ + .int12 /* sizeof(multiboot_header_tag_information_request) */ + /* + sizeof(uint32_t) * requests */ + .int4 /* MULTIBOOT_TAG_TYPE_BASIC_MEMINFO */ + .align 8 + + .int3 /* MULTIBOOT_HEADER_TAG_ENTRY_ADDRESS */ + .int16 /* sizeof(struct multiboot_tag_efi64) */ + .quad (multiboot2_entry - KERNBASE) + .align 8 + + .int9 /* MULTIBOOT_HEADER_TAG_ENTRY_ADDRESS_EFI64 */ + .int16 /* sizeof(struct multiboot_tag_efi64) */ + .quad (multiboot2_entry - KERNBASE) + .align 8 + +#if notyet + /* +* Could be used to get an early console for debug, +* but this is broken. +*/ + .int7 /* MULTIBOOT_HEADER_TAG_EFI_BS */ + .int8 /* sizeof(struct multiboot_tag) */ + .align 8 +#endif + + .int0 /* MULTIBOOT_HEADER_TAG_END */ + .int8 /* sizeof(struct multiboot_tag)

But in order to retreive kernel symboles, the NetBSD kernelneeds symbol
table and string table sections to be loaded in memory, and have an
address set in the section table.

src/sys/arch/x86/acpi: acpi_machdep.c
Log Message:
Attempt to obtain ACPI RSDP from the hypervisor for Xen PV
There are three possible way of obtaining the ACPI RSDP
- From Extended BIOS Data Area (EBDA) when kernel or Xen was booted from
BIOS bootstrap
- From EFI SystemTable when kernel is booted from EFI bootstrap
- When Xen is booted from EFI bootstrap, EBDA is not mapped, and EFI
SystemTable is not passed to the kernel. The only way to go is to
obtain ACPI RSDP trhough an hypercall.
Note: EFI bootstrap support for booting Xen has not yet been committed.

CVS commit: src/sys/arch/x86/acpi
Module Name:src Committed By: manu Date: Thu Sep 12 00:52:22 UTC 2019 Modified Files: src/sys/arch/x86/acpi: acpi_machdep.c Log Message: Attempt to obtain ACPI RSDP from the hypervisor for Xen PV There are three possible way of obtaining the ACPI RSDP - From Extended BIOS Data Area (EBDA) when kernel or Xen was booted from BIOS bootstrap - From EFI SystemTable when kernel is booted from EFI bootstrap - When Xen is booted from EFI bootstrap, EBDA is not mapped, and EFI SystemTable is not passed to the kernel. The only way to go is to obtain ACPI RSDP trhough an hypercall. Note: EFI bootstrap support for booting Xen has not yet been committed.
