In Background to the Daf, the Kollel writes:
>> 5 ) [line 12] LISHKAS BEIS HA'PARVAH - a room in the Beis ha'Mikdash where hides of various offerings were tanned. The Rishonim suggest various reasons for how this room received its name. According to the RASH (Midos 5:2), the word "Parvah" is related to "Parim" (cows), the hides of which were tanned there. Alternatively, a Mikvah located on the roof of this room was used by the Kohen Gadol on Yom ha'Kipurim (Yoma 34b; Parvah is related to the word "Kipur"). Another possible explanation is that a non-Jewish sorcerer named Parvah designed this room with an ingenious system for bringing water to its roof (ibid., as explained by TIFERES YISRAEL, based on Yoma 35a). Alternatively, a non-Jewish sorcerer named Parvah built a tunnel from Yerushalayim which emerged within the walls of this Lishkah for the purpose of observing the Kohen Gadol while he performed the Avodah on Yom Kipur. He was caught and put to death, and the event was memorialized through the name of the Lishkah. (RAMBAM Peirush ha'Mishnayos Midos 5:2; TOSFOS DH Parvah and RABEINU CHANANEL Yoma 35a) <<
Shas Lublin brings that the ROSH in Midos Perek 5 Mishna 3 says Parvah was Jewish. (Based on a Pasuk in Ezra Chapter 4 Posuk 3)
They also mention the Rav on the mishna says he built the Lishka through Kishuf.
(I didn t check the sources myself to verify them.)

Thank you! We have re-written the Background entry as follows:
*5*) [line 12] LISHKAS BEIS HA'PARVAH - a room in the Beis ha'Mikdash where hides of various offerings were tanned. The Rishonim suggest various reasons for how this room received its name:
1. According to the RASH (Midos 5:3), the word "Parvah" is related to "Parim" (cows), the hides of which were tanned there.
2. Alternatively, a Mikvah located on the roof of this room was used by the Kohen Gadol on Yom ha'Kipurim (as the Mishnah explains in Yoma 34b); Parvah is related to the word "Kipur" (RASH ibid.).
3. The Gemara (Yoma 35a) says that Parvah was the name of a sorcerer. Some explain this to mean that a Jewish sorcerer named Parvah built the room (ROSH Midos 5:3 based on Rashi in Yoma), or that a non-Jew by that name designed the ingenious system that was used to bring water to its roof, as if through sorcery (ibid., as explained by TIFERES YISRAEL based on the RASH ibid.).
4. Others explain the Gemara in Yoma to mean that a non-Jewish sorcerer named Parvah built a tunnel from Yerushalayim which emerged within the walls of this Lishkah, for the purpose of observing the Kohen Gadol while he performed the Avodah on Yom Kipur. He was caught and put to death on the spot, and the event was memorialized through the name of the Lishkah. (RAMBAM in Perush ha'Mishnayos and ROSH, Midos 5:3; TOSFOS DH Parvah and RABEINU CHANANEL Yoma 35a based on ARUCH)
