5 months agopwm: stm32: Fix calculation of prescaler
Uwe Kleine-König [Fri, 21 Jun 2024 14:37:13 +0000 (16:37 +0200)]
pwm: stm32: Fix calculation of prescaler

A small prescaler is beneficial, as this improves the resolution of the
duty_cycle configuration. However if the prescaler is too small, the
maximal possible period becomes considerably smaller than the requested
value.

One situation where this goes wrong is the following: With a parent
clock rate of 208877930 Hz and max_arr = 0xffff = 65535, a request for
period = 941243 ns currently results in PSC = 1. The value for ARR is
then calculated to

ARR = 941243 * 208877930 / (1000000000 * 2) - 1 = 98301

This value is bigger than 65535 however and so doesn't fit into the
respective register field. In this particular case the PWM was
configured for a period of 313733.4806027616 ns (with ARR = 98301 &
0xffff). Even if ARR was configured to its maximal value, only period =
627495.6861167669 ns would be achievable.

Fix the calculation accordingly and adapt the comment to match the new
algorithm.

With the calculation fixed the above case results in PSC = 2 and so an
actual period of 941229.1667195285 ns.

This is because older VMMs that might still call
svm_get_msr()/svm_set_msr() for SEV-ES guests after guest boot even if
those interfaces were essentially just noops because of the vCPU state

get an -EINVAL and generally crash.

Newer VMMs that are aware of KVM_SEV_INIT2 however are already aware of
the stricter limitations of what vCPU state can be sync'd during
guest run-time, so newer QEMU for instance will work both for legacy
KVM_SEV_ES_INIT interface as well as KVM_SEV_INIT2.

So when using KVM_SEV_INIT2 it's okay to assume userspace can deal with
-EINVAL, whereas for legacy KVM_SEV_ES_INIT the kernel might be dealing
with either an older VMM and so it needs to assume that returning
-EINVAL might break the VMM.

Address this by only returning -EINVAL if the guest was started with
KVM_SEV_INIT2. Otherwise, just silently return.

The first hardware watchpoint is not triggered, the root causes are:

1. In hw_breakpoint_control(), The FWPnCFG1.2.4/MWPnCFG1.2.4 register
   settings are not distinguished. They should be set based on hardware
   watchpoint functions (fetch or load/store operations).

2. In breakpoint_handler() and watchpoint_handler(), it doesn't identify
   which watchpoint is triggered. So, all watchpoint-related perf_event
   callbacks are called and siginfo is sent to the user space. This will
   cause user-space unable to determine which watchpoint is triggered.
   The kernel need to identity which watchpoint is triggered via MWPS/
   FWPS registers, and then call the corresponding perf event callbacks
   to report siginfo to the user-space.

No watchpoints were triggered, the root causes are:

1. Kernel uses perf_event and hw_breakpoint framework to control
   watchpoint, but the perf_event corresponding to watchpoint is
   not enabled. So it needs to be enabled according to MWPnCFG3
   or FWPnCFG3 PLV bit field in ptrace_hbp_set_ctrl(), and privilege
   is set according to the monitored addr in hw_breakpoint_control().
   Furthermore, add a judgment in ptrace_hbp_set_addr() to ensure
   kernel-space addr cannot be monitored in user mode.

2. The global enable control for all watchpoints is the WE bit of
   CSR.CRMD, and hardware sets the value to 0 when an exception is
   triggered. When the ERTN instruction is executed to return, the
   hardware restores the value of the PWE field of CSR.PRMD here.
   So, before a thread containing watchpoints be scheduled, the PWE
   field of CSR.PRMD needs to be set to 1. Add this modification in
   hw_breakpoint_control().

There are mainly two types of issues.

1. Some incorrect judgment condition existed in user_watch_state
   argument parsing, causing -EINVAL to be returned.

When setting up a watchpoint, gdb uses the ptrace interface,
ptrace(PTRACE_SETREGSET, tid, NT_LOONGARCH_HW_WATCH, (void *) &iov)).
Register values in user_watch_state as follows:

  addr[0] = 0x0, mask[0] = 0x0, ctrl[0] = 0x0
  addr[1] = 0x0, mask[1] = 0x0, ctrl[1] = 0x0
  addr[2] = 0x0, mask[2] = 0x0, ctrl[2] = 0x0
  addr[3] = 0x0, mask[3] = 0x0, ctrl[3] = 0x0
  addr[4] = 0x0, mask[4] = 0x0, ctrl[4] = 0x0

  addr[7] = 0x12000803c, mask[7] = 0x0, ctrl[7] = 0x610

In arch_bp_generic_fields(), return -EINVAL when ctrl.len is
LOONGARCH_BREAKPOINT_LEN_8(0b00). So delete the incorrect judgment here.

In ptrace_hbp_fill_attr_ctrl(), when note_type is NT_LOONGARCH_HW_WATCH
and ctrl[0] == 0x0, if ((type & HW_BREAKPOINT_RW) != type) will return
-EINVAL. Here ctrl.type should be set based on note_type, and unnecessary
judgments can be removed.

2. The watchpoint argument was not set correctly due to unnecessary
   offset and alignment_mask.

Modify ptrace_hbp_fill_attr_ctrl() and hw_breakpoint_arch_parse(), which
ensure the watchpont argument is set correctly.

LoongArch: Only allow OBJTOOL & ORC unwinder if toolchain supports -mthin-add-sub

GAS <= 2.41 does not support generating R_LARCH_{32,64}_PCREL for
"label - ." and it generates R_LARCH_{ADD,SUB}{32,64} pairs instead.
Objtool cannot handle R_LARCH_{ADD,SUB}{32,64} pair in __jump_table
(static key implementation) and etc. so it will produce some warnings.
This is causing the kernel CI systems to complain everywhere.

For GAS we can check if -mthin-add-sub option is available to know if
R_LARCH_{32,64}_PCREL are supported.

For Clang, we require Clang >= 18 and Clang >= 17 already supports
R_LARCH_{32,64}_PCREL. But unfortunately Clang has some other issues,
so we disable objtool for Clang at present.

Note that __jump_table here is not generated by the compiler, so
-fno-jump-table is completely irrelevant for this issue.
