Some stages are not exposed by the Linux driver (e.g. the PLL B). For
14
those, the reset values are unknown and left to 0 which implies a
15
disabled output.

Once booted in QEMU, the final clock tree is very similar to the one

visible on real hardware. The differences come from some unimplemented
19
devices for which the driver simply disable the corresponding clock.

The BCM2835 CPRMAN is the clock manager of the SoC. It is composed of a
3
gicv3_set_gicv3state() is used by arm_gicv3_common.c in
4
main oscillator, and several sub-components (PLLs, multiplexers, ...) to
4
arm_gicv3_common_realize(). Since we want to restrict
5
generate the BCM2835 clock tree.

arm_gicv3_cpuif.c to TCG, extract gicv3_set_gicv3state()
6
to a new file. Add this file to the meson 'specific'
7
source set, since it needs access to "cpu.h".

174
+ * This peripheral is roughly divided into 3 main parts:
175
+ * - the PLLs
176
+ * - the PLL channels
177
+ * - the clock muxes
178
+ *
179
+ * A main oscillator (xosc) feeds all the PLLs. Each PLLs has one or more
180
+ * channels. Those channel are then connected to the clock muxes. Each mux has
181
+ * multiples sources (usually the xosc, some of the PLL channels and some "test
182
+ * debug" clocks). A mux is configured to select a given source through its
183
+ * control register. Each mux has one output clock that also goes out of the
184
+ * CPRMAN. This output clock usually connects to another peripheral in the SoC
185
+ * (so a given mux is dedicated to a peripheral).
186
+ *
187
+ * At each level (PLL, channel and mux), the clock can be altered through
188
+ * dividers (and multipliers in case of the PLLs), and can be disabled (in this
189
+ * case, the next levels see no clock).
190
+ *
191
+ * This can be sum-up as follows (this is an example and not the actual BCM2835
192
+ * clock tree):
193
+ *

+ * /-->[PLL]-|->[PLL channel]--... [mux]--> to peripherals

the different forms produced by error_setg_file_open and

error_setg_errno isn't entirely convenient.

which means looking for PT_INTERP earlier.

Use the new generic support for NT_GNU_PROPERTY_TYPE_0.
3
Create arm_check_ss_active and arm_check_kernelpage.
4
5
Reverse the order of the tests. While it doesn't matter in practice,
6
because only user-only has a kernel page and user-only never sets
7
ss_active, ss_active has priority over execution exceptions and it
8
is best to keep them in the proper order.

From: Philippe Mathieu-Daudé <f4bug@amsat.org>
1
In the SSE decode function gen_sse(), we combine a byte
2
2
'b' and a value 'b1' which can be [0..3], and switch on them:
3
The realize() function is clearly composed of two parts,
3
b |= (b1 << 8);
4
each described by a comment:
4
switch (b) {
5
5
...
6
void realize()
6
default:
7
{
7
unknown_op:
8
/* common peripherals from bcm2835 */
8
gen_unknown_opcode(env, s);
9
...
9
return;
10
/* bcm2836 interrupt controller (and mailboxes, etc.) */
11
...
12
}
10
}
13
11
14
Split the two part, so we can reuse the common part with other
12
In three cases inside this switch, we were then also checking for
15
SoCs from this family.
13
"if (b1 >= 2) { goto unknown_op; }".
14
However, this can never happen, because the 'case' values in each place
15
are 0x0nn or 0x1nn and the switch will have directed the b1 == (2, 3)
16
cases to the default already.

21
of an sse_op_table with only 2 entries as a result of future bugs
22
in the decode logic.
23
24
Change the checks to assert() instead, and make sure they're always
25
immediately before the array access they are protecting.

Rewrite the systick timer to use a ptimer rather than

The calculation of the length of TLB range invalidate operations
2
in tlbi_aa64_range_get_length() is incorrect in two ways:
3
* the NUM field is 5 bits, but we read only 4 bits
4
* we miscalculate the page_shift value, because of an
5
off-by-one error:
6
TG 0b00 is invalid
7
TG 0b01 is 4K granule size == 4096 == 2^12
8
TG 0b10 is 16K granule size == 16384 == 2^14
9
TG 0b11 is 64K granule size == 65536 == 2^16
10
so page_shift should be (TG - 1) * 2 + 12
2
11
3
This is a bit clearer than open-coding some of this
12
Thanks to the bug report submitter Cha HyunSoo for identifying
4
with a bare c string.
13
both these errors.

Test debug 0 and 1 are actual clock muxes that can be used as sources to
15
other muxes (for debug purpose).
16
17
Sources 4 to 9 are mux specific and can be unpopulated (grounded). Those
18
sources are fed by the PLL channels outputs.

20
One corner case exists for DSI0E and DSI0P muxes. They have their source
21
number 4 connected to an intermediate multiplexer that can select
22
between PLLA-DSI0 and PLLD-DSI0 channel. This multiplexer is called
23
DSI0HSCK and is not a clock mux as such. It is really a simple mux from
24
the hardware point of view (see https://elinux.org/The_Undocumented_Pi).
25
This mux is not implemented in this commit.
26
27
Note that there is some muxes for which sources are unknown (because of
28
a lack of documentation). For those cases all the sources are connected
29
to ground in this implementation.
30
31
Each clock mux output is exported by the CPRMAN at the qdev level,
32
adding the suffix '-out' to the mux name to form the output clock name.
33
(E.g. the 'uart' mux sees its output exported as 'uart-out' at the
34
CPRMAN level.)

When compiling with -Werror=implicit-fallthrough, gcc complains about
4
missing fallthrough annotations in this file. Looking at the code,
5
the fallthrough is very likely intended here, so add some comments
6
to silence the compiler warnings.

This patch sets min_cpus field for xlnx-versal-virt platform,
4
because it always creates XLNX_VERSAL_NR_ACPUS cpus even with
5
-smp 1 command line option.

3
The NPCM730 and NPCM750 chips have a single USB host port shared between
4
a USB 2.0 EHCI host controller and a USB 1.1 OHCI host controller. This
5
adds support for both of them.
6
7
Testing notes:
8
* With -device usb-kbd, qemu will automatically insert a full-speed
9
hub, and the keyboard becomes controlled by the OHCI controller.
10
* With -device usb-kbd,bus=usb-bus.0,port=1, the keyboard is directly
11
attached to the port without any hubs, and the device becomes
12
controlled by the EHCI controller since it's high speed capable.
13
* With -device usb-kbd,bus=usb-bus.0,port=1,usb_version=1, the
14
keyboard is directly attached to the port, but it only advertises
15
itself as full-speed capable, so it becomes controlled by the OHCI
16
controller.
17
18
In all cases, the keyboard device enumerates correctly.

Similarly to the Pi A, the Pi Zero uses a BCM2835 SoC (ARMv6Z core).
4
5
The only difference between the revision 1.2 and 1.3 is the latter
6
exposes a CSI camera connector. As we do not implement the Unicam
7
peripheral, there is no point in exposing a camera connector :)
8
Therefore we choose to model the 1.2 revision.

The Pi 3A+ is a stripped down version of the 3B:
4
- 512 MiB of RAM instead of 1 GiB
5
- no on-board ethernet chipset

Add it as it is a closer match to what we model.

The nanosecond unit greatly limits the dynamic range we can display in
4
clock value traces, for values in the order of 1GHz and more. The
5
internal representation can go way beyond this value and it is quite
6
common for today's clocks to be within those ranges.
7
8
For example, a frequency between 500MHz+ and 1GHz will be displayed as
9
1ns. Beyond 1GHz, it will show up as 0ns.
10
11
Replace nanosecond periods traces with frequencies in the Hz unit
12
to have more dynamic range in the trace output.
