Hi, Bibo,

I'm very confused with this series.
1. The cover letter doesn't appear in the maillist.
2. Patch-6 is missed in the thread.
I do not why, maybe it is because my git mail client is configured
with limited smtpbatchsize, since it fails to send in one time with many CC users. Here is git config about sendemail
sendemail.smtpbatchsize=2
sendemail.smtprelogindelay=2

However there is no such problem on lore.kernel.org and my thunderbird mail client. Here is display result of lore.kernel.org
https://lore.kernel.org/lkml/20251104113700.1561752-1-maobibo@xxxxxxxxxxx/

result shown in my thunderbird client:
patch 0: Message-Id: <20251104113700.1561752-1-maobibo@xxxxxxxxxxx>
patch 1:
Message-Id: <20251104113700.1561752-2-maobibo@xxxxxxxxxxx>
In-Reply-To: <20251104113700.1561752-1-maobibo@xxxxxxxxxxx>
patch 6:
Message-Id: <20251104113700.1561752-7-maobibo@xxxxxxxxxxx>
In-Reply-To: <20251104113700.1561752-1-maobibo@xxxxxxxxxxx>
From the In-Reply-To: information, it shows that they are in one mail thread.

3. The one-shot and periodic test splitting is a little strange,
because you put some common parts in the on-shot test, maybe you can
consider merge these two.
well, will merge one-shot and periodic test case.

This patchset adds timer test case for LoongArch system, it is based
on common arch_timer test case. And it includes one-shot and period mode
timer interrupt test, software emulated timer function and time counter
test.

v1 ... v2:
1. Restore PC and PRMD after exception handler.
2. Split patch 4 into two small patches with period timer test and
time counter test.
3. With time counter test, set time count with 0 when create VM. And
verify time count starts from 0 in guest code.
