Define "clock-<freq>" as the preferred node name for fixed-clock and

There isn't much of an existing pattern for names of these nodes. The
most frequent patterns are a prefix or suffix of "clk", but there's a
bunch that don't follow any sort of pattern. We could use
"clock-controller-.*", but these nodes aren't really a controller in any
way. So let's at least align with part of that and use 'clock-'.

For now this only serves as documentation as the schema still allows
anything to avoid lots of additional warnings for something low priority
to fix. Once a "no deprecated" mode is added to the tools, warnings can

clk: imx: imx8mp: Convert to platform remove callback returning void

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

clk: renesas: rzg2l: Extend power domain support

RZ/{G2L, V2L, G3S}-based CPG versions have support for saving extra
power when clocks are disabled by activating module standby.  This is
done through MSTOP-specific registers that are part of CPG.  Each
individual module has one or more bits associated with one MSTOP
register (see table "Registers for Module Standby Mode" from HW
manuals).  Hardware manual associates modules' clocks with one or more
MSTOP bits.  There are 3 mappings available (identified by researching
RZ/G2L, RZ/G3S, RZ/V2L HW manuals):

case 1: N clocks mapped to N MSTOP bits (with N={0, ..., X})
case 2: N clocks mapped to 1 MSTOP bit  (with N={0, ..., X})
case 3: N clocks mapped to M MSTOP bits (with N={0, ..., X}, M={0, ..., Y})

Case 3 has been currently identified on RZ/V2L for the VCPL4 module.

To cover all three cases, the individual platform drivers will provide
the clock driver with MSTOP register offsets and associated bits in this
register as a bitmask, and the clock driver will apply this bitmask to
the proper MSTOP register.

The MSTOP support was implemented through power domains.
Platform-specific clock drivers will register an array of type struct
rzg2l_cpg_pm_domain_init_data, which will be used to instantiate
properly the power domains.

SG2000 series SoC has the same clock as CV1810 series, but the clock
related to A53 is functional in SG2000 series. So a new compatible

Add definition for the clock controller of the SG2000 series SoC.

clk: mediatek: pllfh: Don't log error for missing fhctl node

Support for fhctl clocks in apmixedsys was introduced at a later point
and to this moment only one mt6795 based platform has a fhctl DT node
present. Therefore the fhctl support in apmixedsys should be seen as
optional and not cause an error when it is missing.

Change the message's log level to warning. The warning level is chosen
so that it will still alert the fact that fhctl support might be
unintentionally missing, but without implying that this is necessarily
an issue.

Even if the FHCTL DT nodes are added to all current platforms moving
forward, since those changes won't be backported, this ensures stable
kernel releases won't have live with this error.

clk: meson: g12a: make VCLK2 and ENCL clock path configurable by CCF

In order to setup the DSI clock, let's make the unused VCLK2 clock path
configuration via CCF.

The nocache option is removed from following clocks:
- vclk2_sel
- vclk2_input
- vclk2_div
- vclk2
- vclk_div1
- vclk2_div2_en
- vclk2_div4_en
- vclk2_div6_en
- vclk2_div12_en
- vclk2_div2
- vclk2_div4
- vclk2_div6
- vclk2_div12
- cts_encl_sel

vclk2 and vclk2_div uses the newly introduced vclk regmap driver
to handle the enable and reset bits.

In order to set a rate on cts_encl via the vclk2 clock path,
the NO_REPARENT flag is set on cts_encl_sel & vclk2_sel in order
to keep CCF from selection a parent.
The parents of cts_encl_sel & vclk2_sel are expected to be defined
in DT or manually set by the display driver at some point.

The following clock scheme is to be used for DSI:

xtal
\_ gp0_pll_dco
   \_ gp0_pll
      |- vclk2_sel
      |  \_ vclk2_input
      |     \_ vclk2_div
      |        \_ vclk2
      |           \_ vclk2_div1
      |              \_ cts_encl_sel
      |                 \_ cts_encl -> to VPU LCD Encoder
      |- mipi_dsi_pxclk_sel
      \_ mipi_dsi_pxclk_div
         \_ mipi_dsi_pxclk -> to DSI controller

The mipi_dsi_pxclk_div is set as bypass with a single /1 entry in div_table
in order to use the same GP0 for mipi_dsi_pxclk and vclk2_input.

The SET_RATE_PARENT is only set on the mipi_dsi_pxclk_sel clock so the
DSI bitclock is the reference base clock to calculate the vclk2_div value
when pixel clock is set on the cts_encl endpoint.

14 months agox86/efistub: Call mixed mode boot services on the firmware's stack
Ard Biesheuvel [Fri, 22 Mar 2024 15:03:58 +0000 (17:03 +0200)]
x86/efistub: Call mixed mode boot services on the firmware's stack

Normally, the EFI stub calls into the EFI boot services using the stack
that was live when the stub was entered. According to the UEFI spec,
this stack needs to be at least 128k in size - this might seem large but
all asynchronous processing and event handling in EFI runs from the same
stack and so quite a lot of space may be used in practice.

In mixed mode, the situation is a bit different: the bootloader calls
the 32-bit EFI stub entry point, which calls the decompressor's 32-bit
entry point, where the boot stack is set up, using a fixed allocation
of 16k. This stack is still in use when the EFI stub is started in
64-bit mode, and so all calls back into the EFI firmware will be using
the decompressor's limited boot stack.

Due to the placement of the boot stack right after the boot heap, any
stack overruns have gone unnoticed. However, commit

  5c4feadb0011983b ("x86/decompressor: Move global symbol references to C code")

moved the definition of the boot heap into C code, and now the boot
stack is placed right at the base of BSS, where any overruns will
corrupt the end of the .data section.

While it would be possible to work around this by increasing the size of
the boot stack, doing so would affect all x86 systems, and mixed mode
systems are a tiny (and shrinking) fraction of the x86 installed base.

So instead, record the firmware stack pointer value when entering from
the 32-bit firmware, and switch to this stack every time a EFI boot
service call is made.

table setup needed to encrypt the kernel (using pgd_none(), p4d_offset(),
etc.). Since the variables haven't been set, the page table manipulation
is done as if 4-level paging is active, causing the system to crash on
boot.

While only a subset of the assignments that were moved need to be set
early, move all of the assignments back into check_la57_support() so that
these assignments aren't spread between two locations. Instead of just

commit 8bf26758ca96 ("x86/fpu: Add XFD state to fpstate") introduced a
per CPU variable xfd_state to keep the MSR_IA32_XFD value cached, in
order to avoid unnecessary writes to the MSR.

On CPU hotplug MSR_IA32_XFD is reset to the init_fpstate.xfd, which
wipes out any stale state. But the per CPU cached xfd value is not
reset, which brings them out of sync.

As a consequence a subsequent xfd_update_state() might fail to update
the MSR which in turn can result in XRSTOR raising a #NM in kernel
space, which crashes the kernel.

To fix this, introduce xfd_set_state() to write xfd_state together
