1.605 Wed Aug 09 09:36:26 GMT 2023 andvar viadrmums(4): build legacy VIA DRM UMS driver module for amd64.

This driver is not built-in by default, thus loadable module can help (un)lucky
owners of 64-bit capable VIA (Nano/Eden) systems or early AMD/Intel systems
with some VIA chipsets, which include VIA integrated graphics.
I also boldly added product IDs for few later models from VX8xx/VX9xx chipsets
without 3D support (DX9_0) to "expand" the driver support to more systems.
Tested successfully basic functionality on VX800, and partially successfully
on VX900 (on VX900 Xorg failed to initialize due to openchrome related issues,
viadrmums attaches and it is by used the driver).
Didn't test on VX855, I don't have one.

Pull up to netbsd-10 is needed.
1.561 Sat Feb 08 07:07:06 GMT 2020 maxv Retire KLEAK.

KLEAK was a nice feature and served its purpose; it allowed us to detect
dozens of info leaks on the kernel->userland boundary, and thanks to it we
tackled a good part of the infoleak problem 1.5 years ago.

Nowadays however, we have kMSan, which can detect uninitialized memory in
the kernel. kMSan supersedes KLEAK: it can detect what KLEAK was able to
detect, but in addition, (1) it operates in all of the kernel and not just
the kernel->userland boundary, (2) it requires no user interaction, and (3)
it is deterministic and not statistical.

That makes kMSan the feature of choice to detect info leaks nowadays;
people interested in detecting info leaks should boot a kMSan kernel and
just wait for the magic to happen.

KLEAK was a good ride, and a fun project, but now is time for it to go.

Discussed with several people, including Thomas Barabosch.

1.282 Sun Jul 18 09:29:11 GMT 2010 jruoho Merge a driver for ACPI CPUs with basic support for processor power states,
also known as C-states. The code is modular and provides an easy way to add
the remaining functionality later (namely throttling and P-states).

Remarks:

1. Commented out in the GENERICs; more testing exposure is needed.

2. The C3-state is disabled for the time being because it turns off
timers, among them the local APIC timer. This may not be universally
true on all x86 processors; define ACPICPU_ENABLE_C3 to test.

3. The algorithm used to choose a power state may need tuning. When
evaluating the appropriate state, the implementation uses the
previous sleep time as an indicator. Additional hints would include
for example the system load.

Also bus master activity is evaluated when choosing a state. The
usb(4) stack is notorious for such activity even when unused.
Typically it must be disabled in order to reach the C3-state,
but it may also prevent the use of C2.

4. While no extensive empirical measurements have been carried out, the
power savings are somewhere between 1-2 W with C1 and C2, depending
on the processor, firmware, and load. With C3 even up to 4 W can be
saved. The less something ticks, the more power is saved.

'disable acpi' should be a workaround. ACPI-enabled kernels works fine
on pre-acpi hardware.
for amd64:

- get rid of the bootfloppy-big.fs boot image, and got to a 3-floppy boot
image
for i386:
- introduce INSTALL_LARGE which has ACPI and some devices with big firmware
- move some devices from INSTALL to INSTALL_LARGE
- Boot floppies still use INSTALL, and bootfloppy-big.fs is still there
(for thoses who want to build el-torito floppy emulation boot CD) and use
INSTALL.
For both, drop the 'iso-image' code in etc/ to make the iso bootable, we'll
use something else to build bootable CDs.

1.989 Sat Jul 24 00:45:54 GMT 2010 jym Welcome PAE inside i386 current.

This patch is inspired by work previously done by Jeremy Morse, ported by me
to -current, merged with the work previously done for port-xen, together with
additionals fixes and improvements.

PAE option is disabled by default in GENERIC (but will be enabled in ALL in
the next few days).

In quick, PAE switches the CPU to a mode where physical addresses become
36 bits (64 GiB). Virtual address space remains at 32 bits (4 GiB). To cope
with the increased size of the physical address, they are manipulated as
64 bits variables by kernel and MMU.

When supported by the CPU, it also allows the use of the NX/XD bit that
provides no-execution right enforcement on a per physical page basis.

Notes:

- reworked locore.S

- introduce cpu_load_pmap(), used to switch pmap for the curcpu. Due to the
different handling of pmap mappings with PAE vs !PAE, Xen vs native, details
are hidden within this function. This helps calling it from assembly,
as some features, like BIOS calls, switch to pmap_kernel before mapping
trampoline code in low memory.

- some changes in bioscall and kvm86_call, to reflect the above.

- the L3 is "pinned" per-CPU, and is only manipulated by a
reduced set of functions within pmap. To track the L3, I added two
elements to struct cpu_info, namely ci_l3_pdirpa (PA of the L3), and
ci_l3_pdir (the L3 VA). Rest of the code considers that it runs "just
like" a normal i386, except that the L2 is 4 pages long (PTP_LEVELS is
still 2).

- similar to the ci_pae_l3_pdir{,pa} variables, amd64's xen_current_user_pgd
becomes an element of cpu_info (slowly paving the way for MP world).

- bootinfo_source struct declaration is modified, to cope with paddr_t size
change with PAE (it is not correct to assume that bs_addr is a paddr_t when
compiled with PAE - it should remain 32 bits). bs_addrs is now a
void * array (in bootloader's code under i386/stand/, the bs_addrs
is a physaddr_t, which is an unsigned long).

- fixes in multiboot code (same reason as bootinfo): paddr_t size
change. I used Elf32_* types, use RELOC() where necessary, and move the
memcpy() functions out of the if/else if (I do not expect sym and str tables
to overlap with ELF).

- 64 bits atomic functions for pmap

- all pmap_pdirpa access are now done through the pmap_pdirpa macro. It
hides the L3/L2 stuff from PAE, as well as the pm_pdirpa change in
struct pmap (it now becomes a PDP_SIZE array, with or without PAE).

- manipulation of recursive mappings ( PDIR_SLOT_{,A}PTEs ) is done via
loops on PDP_SIZE.

See also http://mail-index.netbsd.org/port-i386/2010/07/17/msg002062.html

No objection raised on port-i386@ and port-xen@R for about a week.

XXX kvm(3) will be fixed in another patch to properly handle both PAE and !PAE
kernel dumps (VA => PA macros are slightly different, and need proper 64 bits
PA support in kvm_i386).

XXX Mixing PAE and !PAE modules may lead to unwanted/unexpected results. This
cannot be solved easily, and needs lots of thinking before being declared
safe (paddr_t/bus_addr_t size handling, PD/PT macros abstractions).
